Subject: [PATCH 10/75] LOCAL: usb: hub: disable autosuspend for Genesys Logic
|
|
Hubs
|
|
|
|
Disable autosuspend in Genesys Logic hubs to allow USB devices on the
|
|
Odroid C2 board to be used. The alternative to this patch is setting
|
|
usbcore.autosuspend=-1 in boot params.
|
|
|
|
This patch only impacts GXBB devices as GXL/GXM onwards use the newer
|
|
dwc3 core which does not have the problem.
