Yamaha PSR 290 USB device not recognised. No Midi connection?!

After previously connecting the keyboard with complete success, it has stopped working completly. Now whenever i plug in the UBB Midi in cable windows xp says: USB device not recognised. "Unknown Device" and is useless. Could there have been a nasty malfunction? What shall I do to fix this problem?

How do you change the accompaniment voice on the PSR-290?
I lost the manual and have not a clue on how to do this.

Thank you.

difference between the psr-290 & psr-292

Can anyone tell me the difference between the psr-290 and psr-292. I have a 290, would like another, but can get a used 292 very reasonable. If anyone knows the difference, I would appreciate an answer. Thanks
