Certainly. However the problem starts when your device is identified as full speed rather than high speed, and that identification is made within ehci-hcd. Maybe you could try taking the entire drivers/usb/host directory from 2.6.21, putting it in a 2.6.20 source tree, and building it. I don't know if that will work, but it's worth a try. > Or are there other patches prior to 2.6.21-rc1 that I can try? To get the complete set of changes you need to use Git. Then you can perform a bisection to find exactly where the problem starts. Linus Torvalds recently posted a message including a quick summary of how to do this.
