have you tried it?
I have one more desktop to update and I will try it. The problem, I think, is that the files have not been offloaded to the computer when it decides it can't continue. Since my computers are set up with a D: partition, I simply loaded the files to the D partition and ran it from there. Everybody should have a D: partition for USER files. It makes life a lot easier.

Also, I think the only USB items that affect it are drive type item, thumb drive, external drives, etc. a KBD does not, nor a mouse dongle.
