[Bug 247960] Re: initrd image is read really slowly when booting from USB2.0 HDD

[valus]

I doubt the problem is in Grub. This happens when the BIOS doesn't
support USB 2.0 at BOOT TIME, so it uses the slower 1.1 (you should see
your hdd recognized as a 1.1 device when the system is starting). Once
your OS loads, you have full 2.0 support, that's why lspci output is
useless in this case, the problem is in the BIOS, not in linux. I know
for sure that many Acer notebooks do this... don't know about HPs
though.
