How to enable usb device support in grub

[Wasim Khan]

Hi,

I used below steps to build grub. Grub is not identifying USB devices 
plugged-in to board . Is any driver/configuration need to be enabled ?


  *   git clone git://git.savannah.gnu.org/grub.git; cd grub
  *   git reset --hard 529818738fb2aafb05721830dc99cc6c8736a048
  *   Set toolchain path and 'export CROSS_COMPILE=aarch64-linux-gnu-'
  *   ./autogen.sh
  *   ./configure --target=aarch64-linux-gnu
  *   make
  *   echo 'configfile ${cmdpath}/grub.cfg' > /tmp/grub.cfg
  *   grub-mkstandalone --directory=./grub-core -O arm64-efi -o BOOTAA64.EFI 
--modules "part_gpt part_msdos" /boot/grub/grub.cfg=/tmp/grub.cfg







Thanks,
