We've got a new board and I have not been able to get USB working. I don't believe it is a hardware issue as all signals look good and the design matches the reference designs. I checked CFGCHIP2 Register and it reads 0x00309F2 which is everything I would expect. Checking the logs I find errors so I wonder if the kernel is configured correctly?

If I insert a USB Thumb drive it doesn't get enumerated and nothing is written into dmesg,
Does anyone have any ideas what else I can check? I've attached my config file and I'm using linux-3.3-psp03.22.00.06.sdk from the mcsdk_1_01_00_02 package.
Thanks,
George
