Err… My PROLiNK USB Keyboard is not supported by Samsung Galaxy S II USB OTG. Oh, I should use ‘was’ instead of ‘is’ because I managed to get it working on Samsung Galaxy S2 now. Thanks to XDA Developer, Td8f4. Without his patch, my USB keyboard is still detected as “High-power USB device connected ~ Unable to access this device. Connected device needs external power supply”. No worry if your USB keyboard is not working too, try below patch and it might works like mine…
