I recently got a disturbing problem on my studio workstation - I was stupid enough to install iTunes, realized the havoc it made to services and general resources so I uninstalled it. Unfortunately my 4-port USB-Hub ceased to serve me afterwards, had to reset and move it to the first USB-port on my mainboard to get it working. All seemed fine, however after abt. 30 min uptime it gets saggy, a DPC latency check reveals nasty 1000+ms glitches every 3-4 sec. This ofcourse makes the machine totally unusable for audio/video production.
I check the Devices panel and find a new "other devices" subsection, filled with OVER 200(!!) "Unknown Devices". I've NEVER ever seen something remotely similar (see attachments)... these are ofcourse the culprits to my Windows 7 sag so they need to go.
Why do these appear without hardware or services/software demanding hardware, and how can remove these?? Preferrably all at once (not possible in device manager), but stopping them from reappearing after I uninstall them one by one would do by far.
What I already have checked so far:
- that nothing starts on boot that shouldn't (user, all users and registry)
- that no unfamiliar services are running
- that there are definately NOT 250 hardware peripherals connected.
- that all drivers
are installed correctly - the unknowns are all ghosts in addition to these..
If anyone has some tricks, tips or things to try I would be insanely grateful, I need my studio working longer than 30-40min, it's hopeless...
