Mike start with the minimum complexity on this one. Unplug your device
then plug it in, and look at output of 'dmesg' and 'lsusb' to verify which
device it detects.
There are some very ancient threads here for FO station craziness with
solutions saying unplug and remove/reinsert batteries from the station and
the like, but lets see what your USB setup looks like. Telling us which
model station and whether you're using a usb multiport thing or connecting
directly to the pi might help too.
