Hi! I used dd to place the gentoo minimal-livecd to a 4GB flashdrive and installed gentoo on my laptop yesterday with it without hickups. However I got a major problem (major for me) with the same usb-livecd on my desktop pc. While booting, after the kernel bootoptions prompt all usb-devices "shutdown" and are "reinitialized" (the lamps on my keyboard start glowing again) and with this the usbdrive is disconnected too. I get an error message complaining that the root filesystem is not accessible (that is the one on the livecd). I tried booting the same image burned to a cd and the keyboard and all other usb devices still were nonfunctional until I got to the bash shell/install prompt where the keyboard was functioning again. Naturally, the boot went fine since it was made with a CD over a SATA disc-reader. I have bought an X99 motherboard, it's an Asrock X99 Extreme3 which I first assumed to be responsible. The weird thing is Archlinux's livedvds/cds boot just fine on it from a usb. The assumption I've made is that something is up with this motherboard, the UEFI settings or the liveimage. I would like to start with the liveimage having some issue because a similar problem doesn't not occur if I use other images to boot an installation of, say Archlinux for example. Gparted live usb works fine too.
quite possibly bug #522176, it loads xhci_hcd but not xhci_pci so usb 3.0 ports drop out

Thanks for the quick responses! I had no idea how to find that bug so I wouldn't have put this one here if I knew there was a duplicate. Searching for "usb boot install" didn't really yield any results applicable.
