How do you read/write a usb device connected to a Raspberry Pi with mathematica? I can see the device (AD5933 eval board) that is connected to the hub that is attached to the rpi. ControllerInformation[] returns:
No Controller devices detected from the rpi.
So no USB devices are detected by Mathematica but lsusb returns

FindDevices[] returns

Needs::nocont: Context ANTConnector` was not created when Needs was evaluated.

Devices[] returns the same list as FindDevices[] but without the error messages. Is it possible to use something like this?
DeviceOpen["Serial",{"/dev/ttyUSB0","BaudRate"->9600}]
I don't see a /dev/tty?? for my USB device however. I see /dev/usb/hiddev0 but don't know how to access the individual device connected to the hub.
