I'm using the linux v 3.13.0 / IMX6. We need to validate USB test modes as specified in USB 2.0
I have understand that, the ehci-hub driver is limited to support test modes from 01 (J_STATE) to 05 (FORCE_ENABLE_HS).
Since the test modes 06 (FORCE_ENABLE_FS) and 07 (FORCE_ENABLE_LS) also specified in USB 2.0, why these test modes are limited from ehci-hub driver?
I can update the driver to remove this limitation, but what would be reason these tests are limited in the driver?
Thanks in advance.
