My Audya won't always connect to my computer via USB.
It will connect then reset and say Loading Audio Resources.

I've tried different USB cables, different ports on my computer and even a different laptop.
I also tried a USB hub and can get it to work that way sometimes.

Sometimes it will connect and I can transfer some files, then it eventually resets.

My checksums are OK (except for the known one that gives an incorrect value)

This didn't seem to be a problem before the OS upgrade.
Anyone else have this problem? Suggestions?
Thanks
