At least 2.4.5-ac6 still generates this kernel hang, and can be made
to do it for full speed devices too.
How to reproduce with usb-storage and a USB 1.1 device and any
host controller (well, at least all combinations I've tried):
- add to usb-storage/transport.c, about line 1145,
a call to wait_ms(10000) ... after reading CSW
[ smaller values might work too ]
- rebuild, modprobe, etc
- connect a bulk-only usb-storage device
- watch the blinking lights stop ... :)
Anyone have a clue why that gives a hard lockup? Seems
likely that'll the same root cause for the high speed version.
