HI Jianming Liao,

I would like to ask you some questions which could be helpful for investigation of the issue.
What hardware you are using and which software and kernel version?
Are you using DMA and if true which DMA mode?
Are you using double buffering and if it is true what is the size?

The usb driver in linux-2.6.37 enable dma by default!
