USB

A utility is provided in /home/linaro/bin to change the configuration of the host (Type A and Expansion) and OTG USB ports. By default these ports operate in low/full speed modes (1.5/12 Mbits/s) to support mouse/keyboard devices. Other USB devices such as network or storage dongles/sticks will be limited to full speed mode. Using the usb_speed utility it is possible to support high speed devices (480 Mbits/s) as long as they are not mixed with full/low speed devices.

For information on using the utility do the following:

$ sudo usb_speed -h
