https://bugzilla.kernel.org/show_bug.cgi?id=209555 --- Comment #25 from Yunhao Tian (t123yh@xxxxxxxxxxx) --- Hi remyvarma, Are you using a rockchip device? I copied dwc2 driver from https://github.com/rockchip-linux/kernel/tree/develop-4.19 , replaced the mainline dwc2, did some porting work, and everything starts working. I'm not very sure what's the difference, but it just works. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
