Subject: [PATCH] ralink: fix USB host function for Intenso M2M
The ubootloader of the M2M sets the reset bits for
both USB device and USB host during initialization
(to save a few mA of power during boot).
However, for the usb<->sata bridge to be properly
detected, it is necessary to clear both reset bits
as otherwise the kernel logs will just be filled
with:
usb 1-1: device descriptor read/64, error -145
