I am running on windows Vista, 32bit. All USB ports are not working (front & back). yellow exclamation mark showing in device manager for USB ports. Power is going to the ports but no device is recognised. Driver updates say that it is up to date. Windows update will only get to stage 2 of 4. Any ideas/suggestions of what we could try next please?
Yes just looking at that. Yes happened all of a sudden, was working 11/07 and now it won't! camera recognises it is plugged into USB but USB does'nt recognise that the camera is plugged in. Will not recognise any other devices either, e.g printer, memory stick
I am a friend of deneka's and i was down her house on sunday trying to help with this problem. Have not tried uninstalling the ports themselves only the drivers and then re-installing. So, should i right click and try uninstalling the host controllers or all of them? And if i did windows would detect this on reboot? Could it maybe just be a missing .dll file?
Turned out to be an issue with Kaspersky. Tried all of the recomended methods suggested with no joy but as soon as we renewed Kaspersky, drivers started installing and USB's were fine. *shrug* This is why i dont get on with anti-virus's. Too overprotective sometimes.
