I have an Asus UX32VD running Kernel 3.5.4-1 and KDE 4.9.1
I have the problem, that when connecting an USB Device it is not recognized, by the kernel.
There is no entry in dmesg. No error message or similar.
The Module xhci_hcd is loaded...other "usb" devices, like the webcam or the cardreader are working.
I don't have any idea, where to search for the problem and would be lucky about every input.
Thank's a lot, DX
Arghhh! Sorry...it's working now.
A "restore defaults" in BIOS solved Problem...maybe it had something to do with the BIOS update i've done...
Sigh. Have the exact same problem. Unfortunately, restore defaults didn't help. What seems interesting though is that usb works if you have something connected before booting. Booted with the usb stick connected. After that, I connected the usb ethernet adapert -> detected. After removing the usb stick and reconnecting the asix adapter afterwards, it wasn't detected again. WTH . Should have kept the 2.06 bios.
I don't know how you fixed it with the bios reset, but in my case the problem is the udev rule for runtime power management of the pci devices attached in the wiki page + bios 2.11. I'm using the udev rule since I installed arch 2 or 3 months ago. Since the 2.11 update this udev rule seems to be buggy. After I removed the rule from /etc/udev/rules.d .. usb devices did work again as expected.
Are you also using this udev rule?
Update: Same thing with laptop-mode tools. Seems like I don't need the udev rule anymore. laptop-mode tools enables runtime-pm for the pci devices already. As soon as laptop-mode runs, usb device detection is borked.
