Hi :-) Currently, I tried to support usb camera on the fotg210 host controller but came across a few issues, for example system crash, video streaming error, etc. As fotg210 is an ehci-like controller, I borrowed some ideas from the ehci-hcd driver, and at least the usb camera can work now. By the way, the fotg210-hcd driver seems a bit out of date, is there any plan to update it based on the latest ehci-hcd driver? Thank you!
