Hi,
Thanks for the responses! I'll answer as many questions as I can ..
The RPi (meteopi) running the weather station is part of a small "pi-stack"
housed in a case. It's powered from a 18V switched mode supply, regulated
down to 5V by a buck converter. I've checked the voltage on meteopi with a
scope and it's a tad over 5V, with very little ripple and no "sag". It has
all USB ports connected. Here's the lsusb output ...

So, 3 Logitech webcams and a WX station. The station is a WEA22 from
WeatherEye (now only £55 from Amazon!). The console is self-powered and
connected directly to USB (no hub). One other point worth noting is that
the root file system is held on my network server, not on the SD card.
The raspbian op system is ...
wheezy - 3.18.7-v7
Python version is 2.7.3 and I seem to have versions 0.1.4 and 1.0.0 of
libusb installed - presumably the latter is used. pyusb appears to be 0.4.3.
I've attached a copy of my weewx.conf, but the relevant parts are ...

When the "lockup" occurs (perhaps a better description is "lockout"), a RPi
reboot fixes it, there's no need to do anything to the console, and as
previously mentioned, it happens about once/twice a week.
I hadn't even begun to think about how I'd monitor syslog, but the rsyslog
idea is great - I wouldn't have thought of doing it that way ...
Once again, thanks for the interest, I really appreciate it.
