I have uninstalled SpeedFan and cleaned up everything that seemed related to Wondershare or Apowersoft software.
I'm now thinking it might be good to remove or upgrade other pre-2010 drivers, and have come up with the following list (extracted from the latest dump by looking at timestamps in the output from 'lm ot'):

The ITECIR thing is the driver for the Dell infrared mini-remote; don't know if they have anything newer (I remember that upgrading to 8.0 then 8.1 caused the remote to stop functioning).
Dunno what software PxHelp20.sys and secdrv.sys are associated with.
I will try to find a newer driver for the Ricoh SD card reader (could have some influence on the USB issue?)
Any (other) suggestions? Do you think my list of "old" stuff is complete or should I use other criteria?
