I have an Oregon Scientific WMR100NA that used to work great on my
Raspberry Pi (wheezy, with weewx 3.5.0), but it has been out of commission
for a few months. I fired it back up and ran into all sorts of problems, so
I reinstalled Raspbian with the latest distro (Jessie), and installed the
latest weewx (3.7.1), and I am running into similar problems. It seems that
weewx cannot locate my weather station.
The latest entries of relevance in the /var/log/syslog file are:
Mar 22 22:39:10 raspberrypi weewx[782]: wmr100: Bad USB report received:

I saw some mentions of the driver possibly having issues, so I did try to
update/downgrade the driver that was posted
(/usr/share/weewx/weewx/drivers/wmr100.py), but that gave me other errors,
so I went back to the original driver installed with version 3.7.1.
When I run wee_config --list-drivers, it reports the driver version as
3.3.3. Is that the right version I should be using for this weather station?
Here are the relevant station configuration entries in my weewx.conf file:
[Station]
station_type = WMR100
[WMR100]
stale_wind = 30
driver = weewx.drivers.wmr100
model = WMR100
I tried replacing my power supply with several different power supplies. My
WMR100 is connected to AC power and working normally as a standalone unit,
and I have also tried replacing the USB cable to the weather station
without success.
I recall a command that I used to use to troubleshoot the USB that does not
appear to exist anymore--/usr/bin/wee_config_fousb weewx.conf --check-usb
How can I check Raspbian to make sure it is seeing the USB device properly?
If I unplug and re-plug the weather station, I see the following entries in
the syslog, so I know it is connected:

Any more suggestions where to go next as far as troubleshooting?
