Dear all,
We meet a problem while working with dm6446 and usb camera. The camera can only transfer small packets(under 1024), for dm6446 do not support high-bandwidth ISOC transfer.
So the usb bandwidth with dm6446 can only up to 4.5MBps. But according to the datesheet, dm6446 support high-speed usb which can run up to 480Mbps.
The linux kernel is 2.6.32.
Who know how to solve the problem?
