I wouder what causes -104 error?I have a question,the error received
error CBW causes -104 error,or -104 error causes it receives error CBW?
I find if it receives error CBW,the copy will be aborted after the host
tries several resets.
the debugging log are as belows:
NOTE: I print last three setup packets when it enters my dm320_de_dequeue
function.I save my register value,req->buf,req->acutal at
bulk_out_complete,and i print CBW and registers value
at static int fsg_main_thread(void *fsg_)
while (fsg->state != FSG_STATE_TERMINATED) {
if (exception_in_progress(fsg) || signal_pending(current)) {
printk("the dma ctrl1 is 0x%x\n",usb_ctrl1);
printk("the dma ctrl2 is 0x%x\n",usb_ctrl2);
printk("the usb intr is 0x%x\n",usb_intr);
debug_msg(debug_buf,debug_length);
printk("the fsg->state is %d\n",fsg->state );
handle_exception(fsg);
continue;
}
....
}
I think after that way,i can get the last CBW,when
the fsg enter exception.The registers value are ok.

I mean the copy is aborted,just like descirbing above.But i can start
another copy,and it will work.The windowsXP hosts print
"The param is incorrect".

The debugging log i gave u above.Thank u for look at it .
Sign,it really hard to find where the problem really is.
In my device,there are 2 media,SD card and NAND Flash.
I write and read NAND FLASH through usb is OK.(after
more than half days test).I copy data to(from) SD Card
using network are also ok(without usb,using hard disk,NFS)
But when conterns to usb,the SD card copy is error.
The frequency is several hours (from 2 to 7).
And i find the fsg status can back to normal after
dm320_eq_dequeue at USB enumeration.The logs are belows:

But when concerns the date transfer,just like
the first debugging log,it can't back to normal
after dequeue function.
I have a question,there is an error occurs
when the usb is transfering data,the usb status
(fsg status) can back to normal or not?
I think they can,my dequeue function mostly
follows pxa_udc's.The function are as belows:
static void cancel_dma(struct dm320_ep *ep)
{
if (list_empty(&ep->queue))
return;
cpu_relax();
