Greetings,

This is great discussion that has helped me identify this issue which just cropped up. I recently added a Logitech illuminated keyboard to my XP based PC. Yesterday I got the C5 HID Not Found Error. It frustrated me for about an hour until I came looking for an answer here. Disconnecting the Logitech keyboard cleared up the problem. I will work on it more tonight and see if I can identify/disable the HID that could be causing the problem without having to unplug the keyboard every time I need to connect my 9400.


I have a Vista based laptop as well that has no problem.

Very strange behavior...
