Been using my TR4 w/Clippro for sometime on my Win7/64Bit without any problems.
Then after removal of the TR4 and reconnect Win7 will not see TR4 anylonger, not even visible in "Device manager" list. No yellow unknown devices either.
It's just like nothing happens...
Reinstalled software and drivers without any luck so Win7 must be in some state where it doesn't see the TR4.
Uninstalling doesn't help as the TR4 is still not being seen as a USB device.
For the record I have used many different USB connections to be sure there were enough power but again it have worked like a sharm until yesterday

How can I cleanup registry and the drivers and start from scratch ?
Thanks for any advice,
