The usbmon log shows no problem with the laptop, so there must be something wrong with either the software or the hardware on the Galaxy S2. Lukasz, can you or somebody at Samsung look through this thread and help? http://marc.info/?l=linux-usb&m=133232851609627&w=2 Pham has reported that the Galaxy's OTG port doesn't work when a mouse is attached through a hub. For some reason the mouse keeps disconnecting from the hub. The mouse and hub work okay when plugged into a laptop. Also, looking through his usbmon logs, I found that the interrupt URB sent to the hub completes in less than one millisecond, even though its period is supposed to be 256 ms.
