Swami, Thanks again for help. I compiled I2C Support, though my board doesn't have one. As I noticed, due to dev->bus->probe failure for I2C devices, evm_u35_setup is never called.
Can you suggest some workaround? (calling usb_setup registered USB devise, but crashed kernel later as expected, due to chip was not registered). David.
