This enables the USB 2.0 port of the raspberry compute module 4. --- Platform/RaspberryPi/Drivers/DwUsbHostDxe/DriverBinding.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Platform/RaspberryPi/Drivers/DwUsbHostDxe/DriverBinding.c b/Platform/RaspberryPi/Drivers/DwUsbHostDxe/DriverBinding.c index bada13a6cd..bb228e62d9 100644 --- a/Platform/RaspberryPi/Drivers/DwUsbHostDxe/DriverBinding.c +++ b/Platform/RaspberryPi/Drivers/DwUsbHostDxe/DriverBinding.c @@ -140,7 +140,7 @@ DriverStart ( * UsbBusDxe as of b4e96b82b4e2e47e95014b51787ba5b43abac784 expects * the HCD to do this.
