ehci_pci prevents some usb devices from being recognized

vtd · 2017-08-26 18:38:15

On my Arch installation (fully updated today), some USB devices fail to get recognized by the system when ehci_pci is loaded.
I'm fortunate, though: the wireless receiver for my keyboard/mouse works fine.
After connecting other USB devices (tried on 3 thumb drives and a webcam), dmesg gets flooded with

[992.810427] usb 1-1: new high-speed USB device number 47 using ehci-pci
[  993.180443] usb 1-3: new high-speed USB device number 48 using ehci-pci

The numbers wrap around after 127, sometimes they are skipped. New devices never appear in lsusb output.

The motherboard is from sometime about 2008, so the first thing to suspect was the hardware issue. This isn't my primary working machine, so I entered BIOS setup to see if I had previously made weird changes there and found out, that USB storage devices are available as boot options (manufacturer is detected, so the system is capable of accessing them). I booted up the archiso from one of those drives and device detection was working as expected.

When I

rmmod ehci_pci

device detection on the installed system starts working properly. However, this works also when booting from archiso, without having to unload ehci_pci.
I'm curious about the cause of such different behavior and will be grateful for your suggestions.

I'd first try replacing the input dongle with some "regular" keyboard/mouse and see what happens...

If you say it works with the arch iso then I'd compare kernel versions between the iso and your system as it may be a recent kernel regression. You should also test with the LTS kernel and see if it works properly or not.
