What is the occurrence rate of this IOERROR? Once per attach/detach.

Did you try to connect the USB device to a different port and/or USB HUB.

It might also be that the user-space driver tries to reset the device 
when it sees this error. To figure that out you'll need to enable 
debugging in the UPS software package.
