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?
