This Kingston DTSE9 seems to be really pure evil. I connected it to
TotalPhase Beagle USB 480 and plugged it into a PC and the bloody
stick generates broken packets at the beginning. I suspect this is
so bad that it crashes DWC2 controller if plugged directly into it.

I didn't try investigating it with another EHCI controller yet.
Which CPU do you use on your system?
