According to "musbhdrd usb 2.0 high-speed dual-role controller
Product Specification"
the number of dma channels can be read from register RAMINFO.
it is not always that number of dma channels is MUSB_HSDMA_CHANNELS, some
SOC may have little dma channels.

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
Ok， but the linux-cdc-acm.inf is provieded by us, so I think there should
be something I can learn.
Thanks anyway！

I use the case

and find there is no ZLP after a transfer(4096 bytes), I use the

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

If the enumeration fails, there is always a babble interrupt happen just
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.
