tusb8040a1 rkmr USB hub not detected in k2e

Other Parts Discussed in Thread: TUSB8040A1

Hi,


We have our board using k2e and one USB hub (tusb8040a1 rkmr) connected on USB3.0 line of k2e.

We are able to read and write registers of hub from the u-boot  prompt So, HUB is out of reset. But, When we boot the board then in kernel USB hub is not detected. lsusb command doesn't print tusb8040a1 rkmr entry.


So, Is there any modification required in kernel to support this USB hub or any addition driver is needed to support tusb8040a1 rkmr?
