9G45 USB Host problem

[zengyongping]

Hello everyone,

I use a custom AT91SAM9G45 board and run linux 2.6.30. When I insert two USB high speed devices(HUAWEI 4G module and RT3070 wifi module) and use them at the same time, the wifi usb driver reports error. But if I only use one of them, it's no problem.

Any help is welcomed. Thanks!
