Hello
I am having this issue, possibly occured after an update. Usb ports dont seem to be working. For example if I plug in a usb flash disk while arch is up and running its not working. If I reboot the laptop and the flash is already in the port it is working flawlessly. Could anyone help me with this?

Insert your device, then post the output of dmesg | tail -20

It would also help to know how you had flashdrives 'working' before the update. I assume you had automounting set up, but there are several ways to automount removable media. Or by not working, do you mean you could not even mount them with a `mount` command?

Thank you for the responds.

Here you can find the output of dmesg. Neither fdisk or lsusb output something relevant with the usb flash disk.
It seems just not to exist!

Ouch.
Lets go up a level. Can you post the output of lspci -nn and of lsusb when you have a USB device plugged in?

Hello and thanks for your help so far
http://pastebin.com/Qv290yUz Here is the output of lspci lsusb and the boot log while having the usb plugged in during boot and working.
http://pastebin.com/4RKa8PFd Here is the boot log without the usb plugged in during boot
Hope I won't have to reinstall..

I am having this problem as well. It appears USB hot plugging is broken.

If I run
lsusb -v
This forces the device to be recognized. The question is what is it doing that makes that happen.

running:
sudo rmmod ehci_hcd && sudo modprobe ehci_hcd
forces the detection of usb devices. For me.

If anyone has any ideas as to why this may not be working properly I am all ears. I am not seeing any error messages from this module so I am pretty confused why it only works after it has been removed and reloaded.

I have posted a bug on this: https://bugs.archlinux.org/task/29526 please go add any comments that you may have and vote for it.

OK, lsusb -v or reloading the module fixes the problem for me. I am on a hp probook 4320s.

Do you happen to have anything that might tell the usb ports to autosuspend or go into low power?

I'm having the same problem on a Macbook Pro A1261. Running lsusb-v or reloading ehci_hcd seems to fix the problem.
However, it only affects usb devices plugged in after the system boots, devices plugged in beforehand work, including the keyboard/trackpad, isight camera and bluetooth, which are all on the internal USB system.

Could it possibly be related to a problem I had a while back with laptop-mode-tools? See: https://bbs.archlinux.org/viewtopic.php?id=113611

It most likely has nothing to do with laptop mode tools. I personally have usb auto-suspend disabled. Also, I believe it is disabled by default.

The same problem just appeared for me (HP probook 5465b).
At first I wrote that it happened after last update (not kernel), but then remember that it began before this

We got any updates on this? It is really disturbing + I need to run lsusb -v every 5 minutes for my wireless mouse to work
