The code in question is:
def _find_dev(vendor_id, product_id, device_id=None):
"""Find the vendor and product ID on the USB."""
for bus in usb.busses():
for dev in bus.devices:
if dev.idVendor == vendor_id and dev.idProduct ==
product_id:
if device_id is None or dev.filename == device_id:
log.debug('Found station at bus=%s device=%s' %
(bus.dirname, dev.filename))
return dev
return None
So, it's failing to find your station on USB. Could it be security? Does
the user running Weewx have permissions to read the USB?
You might try to run Weewx from the command line and see what it says. If
my guess about permissions is correct, it will run.
