Hi all：
Using DM368, we build our camera and test usb stability(write and read data long-playing), found some problems.
Test program cannot write data to USB divice, after some times(20s~60s), it can write data correctly again; This phenomenon had happend 30 times in about 16 hours.From the kernel demsg, we can see the following errors repeated.
<3>musb_ep_program 1014: broken !rx_reinit, ep1 csr 0003
<3>musb_host_rx 1696: RX1 dma busy, csr 2020
<6>usb 1-1: reset high speed USB device using musb_hdrc and address 3
<6>sd 1:0:0:0: SCSI error: return code = 0x00050000
<4>end_request: I/O error, dev sda, sector 2354240
