Comment (by phoudoin):

 Well, three remarks:
 1. it's not limited to EHCI, as it's an USB bus manager issue, not a
 controler one.
 2. it's not a page alignment issue, but lack of multiple pages support
 3. the fact that it makes the device not accessible anymore is a
 definitive extra bug, that should be tracking down: an explicitly handled
 error in the stack should not let the device access in a broken state
