Logitech Unifying receiver lag - Nexus 9 Q&A, Help & Troubleshooting

I was using my wireless Logitech desktop set but I noticed some lag after not using it for some seconds. When I keep using the mouse or keyboard there is no problem and everything works fine. But when I stop typing or stop mousing for longer than three seconds, the tablet doesn't recognize any input anymore. When I move the mouse or use the keyboard, nothing happens, but after two seconds any input is recognized again.
So I have to keep typing or else I have to wait some seconds to let the tablet recognize any input. This is unworkable.
I tested it with two desktop sets with two different Unifying receivers. When I use a corded mouse or keyboard, everything's fine. It seems to me that there is some sort of logitech standby mode which the tablet can't handle or something.
What can I do abaout this?

Added logcat of connecting usb, a freeze moment, and the disconnection. But I see nothing wrong there...

I bought an other Logitech Wireless mouse (standard receiver, no Unify) and that one works perfectly. So it looks like it has something to do with Unify, not wireless in particular.
Anyone?!

The Shield tablet has the same issue:

Maybe it has something to do with the Tegra K1?

It is really annoying. My Shield Tablet is fantastic, except for this issue with the keyboard/mouse. Sad panda.

And no solutions yet. Maybe a different kernel will work, but I like to keep my N9 stock (the first months hehehe)

Any solution?
Has there been any solution to this issue yet? I too am having the same problem.

Work Around
I have a work around that seems to fix this issue. For this to work you will need to be root. Also note that this solution will cause all USB devices to remain on at all times and will not survive a reboot. My experience is mostly with linux and very little with android. I expect someone should be able to modify the following script fairly easily for a more permanent solution.
Open your favorite terminal emulator and type the following four commands pressing enter after each:
su
for i in /sys/bus/usb/devices/*/power/control;
do echo on > $i;
done
This script toggles the power control setting for all usb devices from the auto state to always on. Hope this helps!

I have a slight lag with my logitech controller through USB OTG. It's just a split second lag, but it's there right from when you plug it in. Makes it unusable for gaming. No issues whatsoever with my Logitech bluetooth keyboard however.

[Q] Bluetooth mouse

We know that the asus transformer has mouse support with the trackpad. I would prefer to have a full mouse when I I set this up to do typing and office type work.
Can any of you who already have the tablet see if it works with a bluetooth mouse?
I will test this when I get home this evening. I meant to test it last night and in the excitement of getting the transformer, I forgot.

Wow didn't even know this was supported so well. Pairing up brings up a mouse pointer until the connection is lost.
LMB obviously simulates touch.
RMB is the back hotkey
MB3 is the menu hotkey (top right icon)
Scroll up-down traverses open menus. LMB to select. Will scroll in the browser and system wide such as in polaris office.
Full movement as expected from desktop OSs.

That is great news. I want to be able to plug my tablet into my hdmi next to my tv to watch videos and sit back on my couch and navigate. That is awesome, thanks for testing it out!
What about zooming in and out? How do you do that if you can't do multi-touch pinch gesture? Perhaps some sort of combination of button press + scroll wheel?

You still get double click to zoom. Other that that you can't be more precise from just the mouse and I don't have a dock or bt keyboard to try.
Only time I see myself using a mouse is when plugged into hdmi and I feel double tap to zoom and reflow is sufficient.
I wish RMB emulated a long press. I feel that is more natural for a right click. Hopefully this can be altered once HC goes open source.
Pairs with Apple bluetooth mouse and links to input device, but nothing happens. Certainly don't get the pointer that could be seen on the screenshot in the earlier thread.

Hi mate,
I'm having trouble pairing my BF mouse with the transformer. I can see it, but when I try to pair them, the transformer asks for pin and basically that's it... nothing after that.
How did you pair yours?

Just entered the default pin 0000. Check the mouse label if it has a specific pin.

Not one of my Apple peripherals connect and work (magic mouse, magic trackpad or keyboard). My Logitech M555b mouse works correctly though.
Makes me wonder if Honeycomb is deliberately blocking Apple devices from working.

That is highly unlikely. When you go into system/usr/keylayout on the XOOM they even have a dedicated layout file for the Apple wireless keyboard. They would be stupid to fuel the flaming between iSheep and Androids! However, I wouldn't be surprised if the Apple mouse requires special drivers, especially if it is the magic mouse which is not your conventional HID. Or maybe Asus has a beef with Apple, but not HC.

I haven't done any digging into the system files yet on the Transformer, so I can't comment on that.
I find it strange though that they all pair, connect but then fail to actually interface correctly. The mouse cursor does not appear on screen, even though the settings panel recognises them as a mouse and trackpad, and the keyboard just doesn't function - the only time it works is when you have to type in the pairing PIN.
Strange.. Might well be an Asus -> Apple issue/incompatibility or something with the bluetooth chip. Perhaps we'll see a future software fix or hack.

The first connection, more than 5 minutes will be automatically disconnected. Need to connect again.
I use a Bluetooth 3.0 Mouse...
Is this the reason?
I tried plugging in the USB transmitter of the Microsoft BlueTrack Mini Explorer and it works, but response is slow.

I am having this issue also. My mouse works fine on my laptop. I think it has to do with the TF going to sleep. I only notice it just before or just after my TF goes to sleep.

Mee too, Works fine on laptop but not Tablet.
This is definately an issue with the TF screen ging to sleep. While I would like it to automatically reconnect. A temporary solution when using the mouse with the dock is to set the screen to stay on when charging.
EDIT: I just installed 3.1 last night and from my experieces today it looks like 3.1 automatically reconnects with the bluetooth mouse after a disconnect.

[Q] Anyone experiencing HDMI Bluetooth lag?

I've posted in other threads about lag i've been experiencing (here, here and here).
As soon as i enable HDMI out the bluetooth keyboard and mouse start lagging and stuttering very badly. This happens with mirror mode (NON-Mod) or Webtop via Nebtop (Root App) or Fenny's mod(replacement APKs). I've run the fastboot on my phone to bring it back to non root stock and i've updated to the 748 VZW OTA update but i still get this issue even just using mirror mode.
Could someone else test this with their RAZR? I'd like to know if it's something defective with my device or with all RAZRs.
The reproduction steps are simple:
1. Pair a bluetooth HID Mouse or Keyboard
2. Connect the input device
3. Connect HDMI
4. Choose output mode (Webtop via hack or Mirror mode with no hacks required)
5. Try to type a text or move the mouse pointer around
I've tried this with different Monitors and televisions and also with different bluetooth mice and keyboards. I haven't found a combination which works smoothly yet. I also posted this issue in the Motorola owners forum. Not too much response there quite yet.
Thanks for the help if anyone can provide it!
I have just ordered my mini HDMI cable. It should be in on weekend so i will keep you posted on my results.
Got my dock station today and will be getting a Bluetooth keyboard in a couple days. I will report back as well.
UPDATE _ Been using the dock station with a Microsoft Bluetooth keyboard and a really cheap USB wireless mouse. The keyboard has no lag at all but the mouse lags a bit depending on what app is running or which dock mode I'm using. I've found that certain games and apps run with less lag in Web top mode and some work better on HDMI mirror mode. I messed with the mouse settings in Web top mode to make it more responsive but it still takes some getting used to. I don't think it's unuseable, but I can see noticeable lag that you have to compensate for.

Same issue on occasion
I have had this happen a few times. I am not sure what is causing it. I will reply back if I have anything further to add.
I don't have a bluetooth mouse or keyboard, but I have noticed a similar delay when playing games via HDMI using a sixaxis or wii controller.
Works fine for me.
Tested with stock UK razr rooted. Nebtop app and apple wireless keyboard and magic mouse. Although mouse behaves weird unless you set up the click rate and sensitivity.
same applies to mirror mode.
I guess its your keyboard/mouse that is causing trouble. Try different set of gear or change batteries.
Hope it helps
That's weird, i tried someone else's logitech bluetooth mouse and got the same issue. It was a mouse only, no keyboard or headphones this time and still had the issues.
I have the same problem. just purchased a dell bluetooth mouse and the apple bluetooth keyboard. they work great in the phone. But once in webtop mode, there is lag. I am using a quality HDMI cable, but use a rocketfish HDMI to DVI converter to the monitor. wondering if that is the issue.?

Can't use Bluetooth keyboard and mouse at same time

I have the Logitech keyboard and mouse for Android tablets, and they WILL NOT play nice together. If I use the mouse, I can't use the keyboard as neither will stay connected, knocking the other out of the connection. I am using rooted, but stock HC 3.2.1 ROM, and this is VERY annoying as I wanted to use it as a laptop replacement and using touchscreen with keyboard is a pain.
When using both, if I move mouse while typing, the keys will stuck and you get words like thiiiiiiiiiiiiiis.
I am able to simultaneously use a Dell Axim bluetooth keyboard and a Dell branded bluetooth mouse with my Stock Honeycomb HTC Flyer. Works like a charm.

I also have the Motorola keyboard + mouse set, and I can report that I can't use the mouse at all. It pairs but never connects.
However, I did try to pair with another mouse and I got the same result as you. Separately, each device worked properly. Together, the mouse knocked the keyboard constantly. I ended up giving up on the mouse, the keyboard is more important
I did send a message to HTC about this problem, and they said the Flyer is probably not compatible with certain devices or certain combos of devices. Standard BS response.

I have this problem, and I have had it before. I am trying to have a desktop replacement via my tablet connecting to desktop as needed. I really need to use a mouse and keyboard, preferably without cumbersom cables. I have an original xoom, this happened on the old ROM and now the JB rom I loaded. If I try to use my bluetooth mouse almost every word eeeeeeeeeeeendsssssssss upppppppppp liiiiiiiiiiiikkee tttttthhhhhhhhhhhhiiiiiiiis. And forget trying to use backspace to correct any mistake, as the backspace key sticks and usually deletes EVERYTHING you typed before you can backup over the 5-10 extra letter repeats you used.
I am surprised this isn't addressed somewhere, I have had this so many times on this and my other tablets. I have even tried various bluetooth keyboard and mice. Even worse, the new microsoft sculpt mouse detects as a keyboard and a mouse, and the "use physical keyboard" button doesn't work (if you click off, it just stays on and shows on, no matter what I do. So if I even attempt to use this new mouse, I can't even get the on-screen keyboard to work.
Right now I have to either use the mouse (and turn the mouse off to type on screen), or turn the mouse off and keyboard on while I type something up. I'm almost in tears as I am partially disabled, and all my attempts to ease myself back into using a computer, I run into new issues.
In short, I can't buy anything new, I really need to use this Xoom for now. I can't use a USB device well, it is too cumbersom, I can't dock it and use the USB, I need to stick with bluetooth. I have a Microsoft Mobile Bluetooth keyboard 6000 and a Microsoft Sculpt Keyboard.
I have tried an app called keyboard helper pro, but it doesn't work at all.
I can use a different ROM, but I would really prefer a newer one as the extra keys and mouse features seem to pass through (such as using the right mouse button, instead of having to hold the left button down, when connected to my desktop.)
Any pointers? I heard something about the bluetooth stack being changed. I haven't found out what/why/how the windows key and right mouse button work (they didn't in older android versions).

[Q] Android confuses Bluetooth gamepad/controller for mouse - Help

I have a Lenovo IdeaTab S6000 and I recently purchased the Red Samurai/GameStop V2 branded Bluetooth controller and I'm finding that when I connect the controller, a mouse cursor appears on screen that can be semi-controlled via the analog sticks. This essentially causes none of the compatible games for the controller to improperly function. Within my tablets setting menu is an option to change a mouse's cursor speed (something not present on my HTC One, which the controller works perfectly on) and I was wondering if this option could be a factor in the overall problem and if disabling this option is possible. I have spent the past two days trying to remedie this problem and have had no luck so any kind of support would be greatly appreciated.
Also, this being my first post, I apologize in advance if this was posted in the wrong area.

Necroposting, but I figured I'd add to the conversation:
The only gamepad that I've gotten to work with this device (as a gamepad) is the Moga Hero. Connecting was always finicky at best and would require a full reboot, and immediately connect when it powers up. Otherwise it wouldn't pair at all.
I've tried the Red Samurai v2, the Nyko Playpad, and most recently the Mad Catz C.T.R.L.R. Invariably, the mouse mode works and works very well, but the gamepad mode always does what was written above.
In trying the xbox 360 gamepad, it blinks but doesn't connect.
As a lark, I purchased a Asus MeMo 7" HD tablet which has the same MediaTek chipset (8125) and the same exact problem exists with that device too (mouse mode works, no gamepad). Both the Memo and the Lenovo tabs are on the same version of Android (4.2.2) and the same kernel (3.4.5) on the stock rom. I assume it's Mediatek's fault, in which case HID gamepads are a no go on these devices.
Unless someone has other information, which would be much appreciated.
Oh, wanted to add something: when the C.T.R.L.R. connects in gamepad mode, you get only a cursor. When I connect my bluetooth keyboard, the multimedia controls start working. Not sure why that is.

Bluetooth mouse and keyboard issues

I have an HP BT mouse and the logitech 810 keyboard and I am finding that they are having difficulties when used with this tablet. I get random multi-repeats on the keyboard, and the mouse pointer has a large delay and is 'jumpy' making it hard to use. I did not have this issue on my transformer prime at all and I routinly used multiple BT devices at the same time. Other then using someting like external keyboard helper pro to reduce theeeeeeeee multi key issue, I have not figured out how to adjust BT to be less jumpy. I have turned off the low power settings and stamina mode.
Any thoughts? Hard to use it the way it is.......

I have the same problem with characters, but thought it was due to poor quality of my keyboard. Will test it with another device then.
It also has a built-in trackpad and it works flawless, except scroll speed is a bit high.

Seems that if I reboot, then BT is smooth for a bit, but then gets jerky again after a little while. Also really lags when wifi is active such as when downloading. Is this a HW issue or a BT config issue. Is there any BT config utilities that may work with this tablet?
Update....
It appears to only happen when more than one bt device is attached. the mouse works fine if keyboard is shut off......

ok. I just tested with my computer and double character still happens, so I guess my original suspicion is correct. My keyboard is of poor quality.
is it possible to adjust the BT profiles at all? My mouse will not 'long press' on the buttons, it instead only does a single click no matter how long you hold it, and the middle and left buttons do nothing. On other tablets these were configurable but there isnt any adjustments in the settings menue for BT or the Mouse and Keyboard that I have found other than layout.
Thoughts?
I have a bluetooth keyboard by Anker (£20 on amazon) also a Hp blutooth mouse and they borh work perfectly. Im rrally surprised they work so well actuall, I never used an bluetooth controllers wirh android before. Maybe its your kit. Setting the connect and disconnect profiles is good.
