Description
When running the USB Chapter9 test from the USB-IF, it seems the simtrace2 firmware is refusing a SetConfiguration (0)

The last message in the test, as captured by openvizsla (SetConfiguration 0):
Compare this to an earlier SetConfiguration 1 which passes the test:
Attaching a full trace from the qmod with hub+sam3s (includes all of the initial bus enumeration) and a shorter trace from a mass-storage device running the same "9.1" test. In the latter the SET CONFIG 0 seems to be ACKed but the device still responds to address 0 ?!?
From the USB mass storage device:
So in this case, there's an IN transaction after the SETUP transaction carrying the SetConfiguration(0)
- % Done changed from 0 to 90
- Status changed from In Progress to Resolved
- % Done changed from 90 to 100
