Windows 7: problem with usb stereo amplifier

problem with usb stereo amplifier


I have cambridge azur 651A stereo amplifier connected to my desktop pc with win7 64bit.

This was working perfectly for half a year, now without any new hw/sw update in this pc it has stopped working.

I have tried to re-install drivers etc but nothing seems to be helping.

I haven't updated to windows 10, and I'm not willing to, just came to my mind if there is now missing some important windows update when I'm not going to win10...

At the moment usb audio device shows code 10, there was some other earlier, 43 if I recall.

I have tried different usb ports on this desktop, and this amplifier works perfectly when connected to laptop win7 with same usb cable.

I did read that you unistalled the drivers,
But can you do it again please, Twice

First with the USB disconnected > uninstall > REBOOT > then in the action option scan for hardware changes.

second with USB connected same instructions.

If these fail can you post a copy of ALL the problem devices,(expand to include show hidden devices) from device manager.

Are you using a USB hub as well.
