AS we received no feedback, we suppose that it was the mentioned problem with root ports.

I will try all suggestions after my holiday, in 2 weeks. I don't have the device here.

Hi,
one more thing:

I am not sure if
GRUB_TERMINAL_INPUT=usb_keyboard
is correct/necessary.

AFAIK, USB keyboard should work without any special settings (at least it works on my PC) -> try to keep default "console" keyword here.

BR,
Ales

Hi,

first question:
Does the sentence "I've built the latest Grub2 from source..." mean that You build GRUB2 from latest revision in BZR repository?

If it doesn't, try build GRUB2 from BZR trunk branch first (To get the latest trunk revision You can use e.g. "bzr branch http://bzr.savannah.gnu.org/r/grub/trunk/grub/").

Second:
As I see, You have built GRUB2 image with "... uhci Ohci" but in grub.cfg You used insmod uhci, insmod Ehci. It doesn't match...

Try in both places combinations "ehci uhci" or "ehci ohci" or only "ehci".

Third:
If it is possible ( if You can run some Linux on this tablet, e.g. some Live distribution or SystemRescueCD from http://www.sysresccd.org/SystemRescueCd_Homepage ), send here output of:
lspci -vvv
lsusb -vvv

If You cannot run any Linux on this tablet, send at least some detailed output/export of e.g. Windows System Information (or whatever similar utility exist in Windows 8, I don't know it...) - it is necessary to know which USB controller(s) and hub(s) is (are) used inside.

BR,
Ales

My goal is to PXE boot a Dell Latitude 10 RT2 Tablet PC to a grub boot manager menu.

Building and pxe-booting a grub-image succeeded. USB Keyboard's are not working however.

The BIOS does not support USB Legacy mode.

I've built the latest Grub2 from source on a Debian 6.0.5 32bit host.

I've built the image using the following command:
./grub-mkimage -c grub.cfg -o grub.efi -O i386-efi boot linux part_gpt fat ext2 normal configfile lspci ls reboot datetime loadenv search lvm help chain usb_keyboard uhci ohci

My grub.cfg contains:
insmod uhci
insmod ehci

My /etc/default/grub contains:
GRUB_TIMEOUT=10
GRUB_TERMINAL_INPUT=usb_keyboard

I get no errors or warnings, the grub shell loads fine, only the keyboard is not working.
