Hi Tormod

Alright, we have an E10 gateway from Synapse wireless that will connect via
cell modem to the internet (thus usb_modeswitch is required). We'll also have
a (TP1080WC) weather station connected which requires the pywws driver to
communicate with the E10 over usb.
Now I have a buildroot environment (BusyBox) with libusb-1.0.8, libusb-
compat-0.1.3 and PyUSB-0.4.3 which I think should resolve all required
depencies. I however when I invoke the "TestWeatherStation.py" script from
pywws, I get these errors:
# python TestWeatherStation.py

Which tell me that there's probably a problem with libusb and/or pyusb...
