I've been trying to get a USB card reader working with VH installed on a RPi. This is the first device I've tried that hasn't worked right off.
The device shows up in the client and I can connect to it. It just doesn't transfer any data. I have the OEM drivers installed and I know that they can communicate with the card reader (the device beeps when I initialize it) but I can't get it to return any data through the driver or as a straight HID keyboard.
Further to this I just tried a generic USB keyboard and I couldn't get it to work either.
