USB devices only detected after Reboot / Suspend

When I plug the USB device into my computer, nothing happens. There are no messages in dmesg and device doesn't appear in lsusb.

However, if I reboot or suspend+resume, the device is detected immediately and gnome open popup shows. When I plug and unplug it afterwards, the same problem persists.

What should I do to debug it further?

Re: USB devices only detected after Reboot / Suspend

What happens if you run "udevadm trigger"?

Re: USB devices only detected after Reboot / Suspend

do you have udev and udisk (or udisk2, since you're using GNOME) installed? are those running?
also, is your user part of the "disk" and "storage" groups?

Re: USB devices only detected after Reboot / Suspend

The problem is not with just USB storage devices, but with other devices too (printers, DVB sticks, mice).

Nothing.

do you have udev and udisk (or udisk2, since you're using GNOME) installed? are those running?
also, is your user part of the "disk" and "storage" groups?

[rok@rok-laptop ~]$ sudo pacman -S udisks2 udev
warning: udisks2-1.94.0-2 is up to date -- reinstalling
warning: systemd-189-4 is up to date -- reinstalling

udev is now a part of systemd. I have had this problem even before I moved to systemd.

[rok@rok-laptop ~]$ systemctl status udisks
udisks.service - UDisks
	  Loaded: loaded (/usr/lib/systemd/system/udisks.service; disabled)
	  Active: active (running) since Tue, 04 Sep 2012 14:46:34 +0200; 2 days ago

Re: USB devices only detected after Reboot / Suspend

is your account in the correct groups? the output of

groups

should contain "storage" and "disk".

Re: USB devices only detected after Reboot / Suspend

[rok@rok-laptop ~]$ id
uid=1000(rok) gid=100(users) groups=100(users),6(disk),7(lp),50(games),91(video),92(audio),95(storage)

But, may I repeat myself:

The problem is not with just USB storage devices, but with other devices too (printers, DVB sticks, mice).

Where can I start debugging?
