My watchdog is a very simple minded one - it regularly (once per minute
using cron) searches /var/log/messages for USB messages. If it detects some
the raspi will be automatically rebooted.
Sadly currently I've no access to my scripts - drop me a note if you still
need it. Then I'll look into that ...
To be honest I do not know why my USB problems were solved. But besides
updating involved software versions, I also started new services (e.g.
Kodi), added an USB diskdrive, and a USB rs232 interface. For that I
changed the USB ports (to avoid cable cluttering:-). Maybe your problem is
simply solved by using another USB port? Or improving contacts by
unplug/plugging?
Regards, Michael
