Hi, I have a box presents to PC as a CDC-ACM device. And I write an simple
Application to write data to the box by ttyACM0.
The application is a loop that write the data to box, and waiting for

The question is , after wrote the data to the box, the box will

hi,
if musb bulk_split is enable, the segment size will be set according
to hw_ep->max_packet_sz_tx, and the segment will be writen to fifo.
But after the first tranfser end, the segment size will be set no larger
than qh->maxpacket (in musb_host_tx),and the bluk_split make no sense.
so p
Hi, On my board, my musb works as host. my kernel version is 3.4.0.
The host cannot enumerate some low speed mouse normally,but if I
add an extersion cord (abour 1.5m) between the host and device, the
mouse can work normally.
If the enumeration fails, there is always a babble interrupt happen just
I use the case
testusb -a -t 1 -s 4096 -c 10
and find there is no ZLP after a transfer(4096 bytes), I use the
Mentor's own DMA
(CONFIG_USB_INVENTRA_DMA). but when just use PIO, there is ZLP.
In the musb_host_tx, the transfer will end with the case
} else if (dma && urb->transfer_buffer_lengt
for me, I will try to re-write the host application.
If I finish the work, will let you know, thanks a lot.

Hi,
I have a cdc-acm usb device, used for transfering data to/from windows PC,
for windows PC, and I use the Documentation/usb/linux-cdc-acm.inf to load the
windows driver(which is the usbser.sys).
On PC, there is an application use the COM port to transfer the data.
During transfer, th
