Re: USB3.0 XHCI support on GRUB2

[Gailu Singh]

Though I get shell but I am unable to use it as keyboard is not working and serial console also does not work because board has only memory mapped UART not supported in grub

There seems to be two controller with vendor and device id as follows

8086:5aa8

8086:5aaa

This is based on lspci output on Linux

Just for reference, what is the PCI product and device ID of that
