The message isn't especially informative! but is indicating something that 'really shouldn't happen (tm)'. The driver recovery clearly needs some improvement. It probably needs to hard reset everything and free off all the memory structures. I'd guess that the output of 'lsusb -t' with everything plugged into the same slots might be interesting, but there is no evidence saved about the actual error. Getting the error every 200us might even mean it keeps processing the same broken event.
