At one point, it looked like this version was working. Or at least I was seeing far more log messages from the USB ISR. But now it doesn't get past the device descriptor:

usb istat 0x01
usb istat 0x08
usb stat 0x00
usb bd tok 0xD
usb setup raw 8006000100004000
usb setup request=6 type=80 value=100 index=0
usb setup get descriptor
usb ep0 transmit 18 byte(s): 12010002ef020140c0168304000101020301
usb istat 0x08
usb stat 0x08
usb bd tok 0x9
usb istat 0x01

Except now, I'm not even getting that... All I get is "usb done" (indicating that machine.USB0.Configure() completed).

@deadprogram @aykevl Any ideas? As far as I can tell, things are failing early enough that Wireshark doesn't see anything.
