I have used several MX850 with my Windows 7 PC and the USB adaptor faultlessley for many years. I went to use it today and it fails.

The MX850 editor gives the usual can't communicate message and the remote screen shows fail !

I have 2 USB adaptors, and the problem is the same with both, just wondered if anyone else had experienced and fixed a similar problem ?

I have done the MX850 reset (hold stop and main for 10 seconds) as well.

I assumed it was a windows 7 update, but I had an old Vista laptop that has been sitting in a box for years, that used to work fine as well with the USB adaptor, and that does not work either, so pretty much out of ideas.

Thanks
