The livecd install-amd64-minimal-20140904.iso fails to boot from USB. Looking at dmesg it seems to load modules for {e,o,u,x}HCI controllers, but does not detect any USB devices attached. lsusb shows only the usb controller root. usb_storage is loaded, but without detecting any devices it is a little bit useless. (And it also disables usb keyboards, so that's ... not funny) # lsusb Bus 005 Device 003: ID 0557:2260 ATEN International Co., Ltd Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 005 Device 002: ID 0557:8021 ATEN International Co., Ltd CS1764A [CubiQ DVI KVMP Switch] Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 003: ID 0781:556c SanDisk Corp.

(The lsusb output is from a "working" system, just for reference)
install-amd64-minimal-20150319.iso and install-amd64-minimal-20150312.iso appear to still be affected by the same issue.
install-amd64-minimal-20150402.iso still/again affected. If, like me, you are using an USB CDROM drive and an usb keyboard the minimal iso completely fails to boot on such hardware: Form the console output: Loading Keymap... (cant't enter anything here) ... !! Meda not found ** No bootable medium found Could not find CD to boot, something else needed ... root block device() :: _ (again, can't enter anything) Lacking PS/2 hardware and an alternative disc drive, I can't further debug but I suppose something's funky in the kernel .config. The install-x86-minimal isos work, as do the admincd-amd64 discs. Also, the install-amd64-minimal-201412XX.iso did run, in other words, 4 months of failed autobuilds in a row.

They seem to lack the support for USB install - so this is a kernel config issue. I'll try to look at the diff when I get home.
Do livecd images not use the standard genkernel? I think I remember I diffed its config a few weeks back and found no USB related changed in the relevant timeframe. Could it be initscripts/ramfs failing to load a module? Someone with PS/2 hardware could easily help narrow this down.
The releng team uses its own kernel config for the installcd / admincd[1]. [1] - https://gitweb.gentoo.org/proj/releng.git/tree/releases/weekly/kconfig/amd64
This are the systemrescuecd configs, maybe that will help us to find the culprit config option as this is supposedly working on that distro: http://sourceforge.net/p/systemrescuecd/code/ci/master/tree/kernelcfg/

Could this be caused by bug 534266?
(In reply to Pacho Ramos from comment #10) > Could this be caused by bug 534266? That bug is about the x86 install-cd and this one is about amd64.

For me the breakage occurred between the December 2014 and January 2015 releases. I did successfully use older media from 2014 as well but I can't say if install-amd64-minimal-20140904 was among them. Just to throw this in here, it might be that this bug only affects UEFI based systems. I tried booting with legacy BIOS as well, with no success.
(In reply to enteest from comment #3) > The install-x86-minimal isos work, as do the admincd-amd64 discs. admincd-amd64-20150514.iso now exibits the same issue. x86 still unaffected. Maybe I'm misinterpreting the vibe (IRC and here) but I got the impression that it's implied if I make noise about a bug it's expected of me to post the patch or at least point out the exact cause as well. However, I really can't debug this and someone familiar with the live media build process should take this on. On a non rolling release distro this would be a major blocker but here it seems no one (releng team, maintainers?) cares. Not to push anyone but this has been open for many months and it's only the very first experience a new Gentoo user will have.
Misreported this issue in another bug (#522172); probable duplicate. Cause listed there. tl;dr: xhci-pci module (makes xhci-hcd actually usable on modern systems) isn't present inside the initrd, this cripples booting via USB3 root hub since all non-embedded examples attach said hub through the machine's PCI bus. ohci-pci module is also missing. This will cripple booting through an OHCI-based USB2 root hub on the PCI bus.
Yes?

The usb devices become attached and active again near where the bash prompt shows. I can tell since the keyboard start working again and typing works but the big problem is that if a usbdrive with a liveimage flashed using dd is used the root is removed during boot and everything fails. Using usbdrives to install is a no go, maybe just on (some) UEFI systems. I am using UEFI and I had no problems on my BIOS PC (non-UEFI).

Just tested this on my XPS 13 9343 (all external USB ports are USBv3). The kernel and initramfs seemed to load, but it got stuck when it tried to mount root (it said "Could not find medium" or something like that). I dropped to a shell and found that xhci_hcd was loaded, but xhci_pci was not. This may be a problem with genkernel not pulling this module when the autobuilds are created. I created bug #554202 in hopes that fixing this issue in genkernel will solve the problem.

The latest install-amd64-minimal-20150806.iso still does not boot on a hp zbook 15 (uefi system, boot in CSM). Everything is ok up to the choice of the keyboard, then the kernel cannot find the USB device with the root filesystem. I am using install-amd64-minimal-20140508.iso, that boots without problems.
I just tested install-amd64-minimal-20150820: it is still not working. As enteest@outlook.com points out, I think that this situation is quite harmful with respect to potential new Gentoo users and should be fixed quickly.
Still the same problem with install-amd64-minimal-20150903.iso... It seems than no one is taking care of this...

install-amd64-minimal-20150924.iso still not work from USBv3 ports on my AMD computers. The same media work on the same computer from USBv2 port. But on computers without USBv2 port is not possible to use it.

it looks like finally all arches have new enough genkernel versions in stable, could this be solved finally then?
Confirmed present and working in 20150225 amd64 iso
