I know nothing
..however having an mr-1000 I googled and found that this chip is commonly used on external usb enclosures.
Basically it seems that under some circumstances the cypress usb chip can lose its EPROM programming, so you can re-flash it and carry on.
Some people with your problem/error message had good luck using the info on this web site:

As a last resort it might be worth a shot..
