The kernel driver sends a data buffer of 8 bytes (command + 7 null bytes) so it would be like this: dev.ctrl_transfer(0x21, 0x09, 0, 0, [command, 00, 00, 00, 00, 00, 00, 00]) The SnoopPro snapshot shows a wValue of 0x200 in the requests, although the kernel driver uses 0. I suppose the kernel driver was tested, but you can still try out: dev.ctrl_transfer(0x21, 0x09, 0x200, 0, [command, 00, 00, 00, 00, 00, 00, 00]) If other code that is proven to work on other people's devices (of same USB ID) does not work on your device, it could be the device is broken, yes... Did you already try WeatherStation.py and Vallentin's kernel driver?
