Ok thanks for the "patch".
I succeeded to use C67x00 driver but without to use the device tree. I will try to use the "patch" to use device tree support.
Have you fixed your interrupt error?
I have a very slow USB bandwidth... Have you problems with reading, writing or bandwidth?

The interrupt error was due to unconnected pins which prevented the clearing of the interrupt.
The bandwidth is not extremely high (due to the lack of DMA, I think I read that somewhere) but enough to drive a USB headset for example.

The bandwidth for me was 600 kbytes/s before I reduced the value TOTAL_FRAME_BW in the driver from 12000 to 4096 because I had writing errors... After that, I obtained a bandwidth of 120 kbytes/s but without reading or writing errors.

Im trying to use the usb port using the linux2.6 kernel
and i have problem with the generator of the device tree
could you please give me some information how make the usb port working with CYPRESS c67x00
