At the moment, I think the best approach is Guido's suggestion to reject 
URBs submitted to endpoints that have gotten a transaction error, until 
the error status has somehow been cleared.  Is that what you would like 
to see automated?

First, just want to point out that I'm not familiar with syzbot. I was
just thinking if this issue occurs, and if the user wants to start a new
test, then she doesn't have to unplug+plug the device back and allow
some application to automatically trigger a new test after a failure.

If you're just talking about syzbot testing, this isn't a issue.  Syzbot 
doesn't test real devices; it tests emulated devices using a 
special-purpose userspace driver.
