After digging into this bug, I found this bug happened randomly. But with the
Lecory USB analyzer, I captured that the last IN packet is wrong in the
CONTROL-OUT transfer. We need to flush the fifo when the whole packet transfer
finished.
Please find the snapshot of the USB capture data.
I fixed this bug both in 08R1 branch and in svn trunk with introducing flush
fifo operation in the musb_g_ep0_giveback function.

I still see this bug on bf548/bf527, with both DMA/PIO mode.
--- Cliff Cai 2009-06-23 02:54:37
This test is to send pattern data( to simulate vendor data) to control
endpoint(CONTROL OUT).Host will repeatedly send a variable length(around 256)
packet to device untill the loop count reaches 15000.When the problem occurs, I
also see a non-zero packet is sent to host after host sends an IN token to
initilate the status stage.Per spec,the device should return a zero-length data
packet to indicate the completion of the transfer.
Cliff
--- Cliff Cai 2009-07-08 21:54:41
Vivi,
Since this pressure test is meaningless in the real word.So,we can change some
parameters for the test.setting the loop count to 50 and packet size to 512 is
enough for real use.
sudo ./src/testusb -D /proc/bus/usb/005/0xx -t14 -c 50
-s 256 -v 1
thanks
Cliff
--- Robin Getz 2009-07-09 12:07:00
sorry - I disagree
Pressure test are there to ensure robustness.
Changing the test (which runs everywhere else) means our implementation may
eventually (and randomly) fail during real world uses.
As you pointed out - the specs say : " the device should return a
zero-length data packet to indicate the completion of the transfer", and we
are not doing that. (we are sending non-zero packet).
With things like USB - there is no "almost" meet the spec - there is
meet or not meet.
Today - we do not meet the spec.
