s3c2410 usb gadget problems with file-storage

Hi,

I am trying to use file-storage on a s3c2412 board with the driver from 
2.6.23.

If I keep stall option on, the driver seems to do the stall before 
sending the packets in its TX queue. So when the host clear the stall, 
the host receive a packet that wasn't waiting for and do a device reset.
I tried to test if PKTRDY was set and return -EAGAIN in 
s3c2410_udc_set_halt but it doesn't seems to work (PKTRDY isn't set).


If I turn off the stall option, it works a bit better. I can format the 
device with FAT, but when I write a file, the file-storate thread seems 
to be stuck in sleep_thread from do_write. And after a timeout, the host 
reset the device.
I need to investigate this a bit further to understand what happen.

Does other people manage to make work file-storage with s3c2410/s3c2412 ?


Thanks


Matthieu CASTET
