Unable to enumerate USB device on port

A few days ago I ran -Syu and updated. After first reboot when waiting for UDev uevents to be processed i got this message and right after that hub 2-0:1-0: connect-debounce failed, port 3 disabled. From then any usb device doesnt work. Today i again ran -Syu but nothing changed. I found some answers on forum but none helps... Any ideas?

uname -a

Re: Unable to enumerate USB device on port

push up.

Same problem here since I updated my system 2 weeks ago ...

EDIT: An old Bug Report says:

I confirm that loading ehci-hcd before uhci-hcd solves the problem. I have a midi to usb cable and on Ubuntu (kernel 2,6,24) it worked but not on Arch (kernel 2,6,27). In another Arch box with an old kernel (can't check right now) the cable worked fine without any special configuration. Great to know that there is a workaround.

which would second this blog solution

How can we try this in Archlinux?

EDIT2:
I read through Arch_Boot_Process
and did a:
mkinitcpio -v
which says somewhere:
adding file: /lib/modprobe.d/usb-load-ehci-first.conf

install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install ohci_hcd $CMDLINE_OPTS
install uhci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install uhci_hcd $CMDLINE_OPTS

maybe this gives us a lead ...

Re: Unable to enumerate USB device on port

try editing /etc/modprobe.d/my_blacklist.conf
----------- snip
blacklist uhci-hcd
----------- snap

and reboot a few times checking output, maybe this is a temporary workaround

Re: Unable to enumerate USB device on port

it's strange that my external hdd, mouse, keyboard or anything that i plug in usb doesn't work, but tethering from phone works without any problem (file sharing doesn't work).

Re: Unable to enumerate USB device on port

Each time I update my kernel I get this problem.  After the next reboot things work again

Re: Unable to enumerate USB device on port

Wow! First time I've got a problem like that with archlinux. I cannot get access to my external usb hard-drives. Is there any solution found yet?

Re: Unable to enumerate USB device on port

I have seen this too sometime when connecting a usb hard-drive that I seldom use.
So I haven't made any research in why and how to fix the problem more than I have notice that if I get that error,
then if I unplug the usb-cable and plug it into another usb-port (if I try plugging it back into the first port just keeps
giving me the same error) then usb-drive is found, no errors given and it works.

Might be worth testing, if it works you at least got a temporary work-around to get your files.

Re: Unable to enumerate USB device on port

For me, it was my USB mouse not working anymore on my laptop, but this thread already gave all hints needed to fix the issue:

# sudo modprobe -vr uhci_hcd
# sudo modprobe -va ohci_hcd
# sudo modprobe -va uhci_hcd

Hello back USB mouse!

$ cat /etc/modprobe.d/usb_hci_order.conf 
#
# create a dependency on ohci for uhci, which fixes problems
# with external usb devices not showing up
#
softdep uhci_hcd pre: ohci_hcd

Cheers

Re: Unable to enumerate USB device on port

Hi everyone!
I am experiencing the same problem here: I tried to do exactly what it was suggested above, but nothing.
I have also tried to disable both ehci and uhci moduels, but in that case I can not use lsusb command.

Any help?
this is very annoying, because these messages are flooding my shell... I can not even type a command that a message appears...

Thanks in advance!
