USB to Ethernet dongle during U-boot

I have recently bought the ASIX8872B usb 2.0 to ethernet dongle and I would like to get it working during the U-boot sequence. I know the driver is in the U-boot source, do I just go through “make menuconfig” and use the correct driver?

Basically I would like to get the USB ethernet dongle to work before kernel is launched.

Thanks.

Hi Kepler3141,

The USB used for Ethernet requires loading of the NVIDIA XHCI firmware to enable the host port. This was implemented in the Linux kernel, but was not implemented within U-Boot.
