[Q] Using USB OTG with external SD card reader? - HTC Flyer, EVO View 4G

Any thoughts/ideas on the following would be welcome. I have got USB OTG working fine on my HTC flyer using an OTG cable and Y cable for external power with a USB pen drive.
However when I try to use the same set up with a USB SD Card reader, I get the message "USB device not supported - The USB device you have connected is not supported. Please unplug both the USB device and the dongle.
Any thoughts on why this is not supported or any fixes?
The card reader works fine with the same 4gb sd card (from camera) on windows PC.

OTG two device

Since I don't have two galaxy's s2 I just wonder if you connect two by using USB and OTG will phone see SD card of other device (using debuging mode on other) and which card will see(internal, external or both). This should work probably for all devices with Android and function to see phone as external disk.
Thx for reply.

For the k900, all you need is a USB OTG cable then you can use maybe a card reader or thumb drive as an external storage drive.

SD Card not recognized when USB connected

Hi All,
Finally I have my Viper ROM installed and working, I just have a question:
When I connect my device to the laptop with USB cable SD card is not recognized.
It's possible to make it visible also when USB connected? I want to use LwW as car mp3 player and I need to have it connected with usb cable.
Regards
Luca
