After upgrading to Linux 3.17, USB HID devices have ceased working when connected directly to my ThinkPad T400's USB ports. Nothing regarding the device appears in dmesg, lsusb, lsinput, etc. Can't type on the keyboard or move the mouse and have a response from the computer. Works fine with sys-kernel/gentoo-sources-3.16.[16]. A keyboard will function as the machine boots up, iff it's connected at power-up. It will continue to function as long as you keep typing (if as the machine boots you keep hitting keys, you can actually type at the login prompt). As soon as you stop, the keyboard ceases to function. In this case, the keyboard DOES appear at /dev/hidraw0. If the keyboard is unplugged and re-plugged in at this point, it will disappear from /dev/hidraw0. Reproducible: Always Steps to Reproduce: 1. Install sys-kernel/gentoo-sources-3.17.[01] on ThinkPad T400 2. Plug in USB mouse or keyboard straight into computer 3. Attempt to use said mouse/keyboard Actual Results: Nothing. Nothing in dmesg, nothing in lsusb, nothing in lsinput Expected Results: Output in dmesg indicating a new USB device has been connected; ability to type on keyboard/move mouse cursor Input devices work OK on my desktop (don't have access to it at the moment to give exact specs- it's custom-built Core i5 Sandy Bridge machine) with sys-kernel/gentoo-sources-3.17.0. emerge --info Portage

I should add that the keyboard/mouse functions as expected when connected through a USB hub. T400 <-> USB keyboard == Doesn't work T400 <-> USB hub <-> USB keyboard == Works
Created attachment 386862 [details] Kernel config for Linux 3.16 (works)
Created attachment 386864 [details] Kernel config for Linux 3.17 (doesn't work)
Last thing- USB flash drives function correctly when connected directly to the USB ports under 3.17
Please attach your full dmesg on after boot
Created attachment 387144 [details] dmesg, booting Linux 3.17.1, keyboard attached after logging in
Created attachment 387146 [details] dmesg, booting Linux 3.17.1, keyboard present at boot time
Appears to be fixed in 3.18.0.
Thanks for reporting.
