Computer info
In response to Computer Geek (thanks), here are the two files requested. I can't point you to the driver I'm trying to install because it's not listed (I guess because it won't install). The error message implies it's an Intel USB Controller driver but you will notice that there is a driver already installed for that. The USB ports seem to be working fine except I couldn't get the Line 6 drivers to recognise my device (it's a UX1 sound card for playing the guitar through the computer sound system). I talked with Line 6 but they say there is no incompatibility problem with Windows 10. This may be a red herring.
