Comment 51 for bug 247960

I do not think that the issue is related generally to bad bioses not supporting USB2.0. Especially in my case I have an option in Bios to either set USB ports to 2.0 or 1.1 at boot. I can also clearly see that it becomes faster when select 2.0 but its still horrible slow to load the kernel+initrd from usb drive.

I have my boot partition on an USB stick which is quite fast when Ubuntu is booted. But when grub loads the files it takes far too long compared to the time it takes to read the same files in OS. I use ext2 and wanted to test if its better on vfat but was unable to get grub boot from the same stick after I just reformated it with vfat and grub-installed'ed it without errors.
