I wanted to try some experiments with this new version, but,=20 unfortunately, something is probably bad in trunk - there is no=20 accessible any disk device after "insmod " ("ls" does not list=20 any device, only empty line). can be (maybe) anything, I tried ehci, uhci, ohci and (non USB=20 driver) ahci. I.e., problem is not related to USB drivers only. For the first look it sounds like there is maybe something wrong with=20 insmod command itself. (I built GRUB from latest trunk on 64-bit Arch Linux.)
