usb ports not working

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?

Re: usb ports not working

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

Re: usb ports not working

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?

Re: usb ports not working

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!

Re: usb ports not working

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?

Re: usb ports not working

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..

Re: usb ports not working

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

Re: usb ports not working

If I run

lsusb -v

This forces the device to be recognized.  The question is what is it doing that makes that happen.

Re: usb ports not working

running:

sudo rmmod ehci_hcd && sudo modprobe ehci_hcd

forces the detection of usb devices.  For me.

Re: usb ports not working

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.

Re: usb ports not working

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

Re: usb ports not working

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

Re: usb ports not working

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.

Re: usb ports not working

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

Re: usb ports not working

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.

Re: usb ports not working

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 tongue
