Hi Mathias,
We have run into a problem with a USB printer which we're quite confident is a
bug in the Linux xHCI driver. There is no problem when the same printer is
plugged into a port managed by the EHCI driver.
The core problem is that xhci_reset_endpoint() doesn't do anything, and

Alan,
I'll get back to you on whether increasing the timeout helps, it'll take a bit
of testing. Does it actually sound plausible that some controllers could not
get things done in 250ms but could in 275ms?
I will note that according to the table in <1>, a 250ms timeout with a HZ=250
