Bug Description
When toggling between DUT and host using a USB LMP Board, I see that the attached USB device will mount on the DUT, but will not show up on the Host.
Steps to reproduce:
1) put latest firmware on Rev2 USB LMP board
2) install lmpd
3) attach a USB flash drive to the LMP board in the "dev test" connector
4) attach host and control mini USB ports to one Linux machine
5) attach DUT mini USB port to a different Linux machine
6) start lmpd and toggle between device and host.
When I select “disconnect” from the web UI, the USB flash drive is not mounted on either the host or DUT. I see the LMP board show up as ttyACM0: USB ACM device.
When I select “device” from the web UI, I see the USB flash drive mount on the DUT, and not on the Host. I see the LMP board show up as ttyACM0: USB ACM device on the host. I am able to access the USB flash drive on the DUT and update the contents.
When I select “host” from the web UI I see nothing mounted on the DUT , and on the Host I see the LMP board show up as ttyACM0: USB ACM device. I was expecting to also see the USB flash drive mount on the host. I don’t see the device enumerating at all and lsusb doesn’t acknowledge that anything is attached.
Hi Dean Arnold /validation. linaro. org/static/ docs/lmp_ test_guide. html#lava- lmp-usb
I don't think that is a bug, please check :

From your description , the behavior of USB module is right.
“disconnect” : disconnect DUT to "test dev" and "host"
“device” : connect DUT to "test dev"
“host” : connect DUT to "host"
