lsusb Outputs Nothing. Is that normal? [SOLVED]

Hello,

I'm trying to get my integrated webcam working on a lenovo x200 and I was unable to find any information about the chipset that the model uses by searching on google. lspci outputs:

and lsusb outputs nothing (even after running "hwd -u" which I thought might help for some reason). This should be giving me something even without anything connected to a usb port, right? Does anybody have any advice?

Yes it should. It would at least tell you the number of ports that you have by giving their ids.

Do you get any error messages? Check dmesg immediately after running lsusb

Nothing new appears in the output of dmesg after running lsusb. Running 'dmesg|grep usb' gives me the following:

ehci_hcd: Unknown symbol usb_hcd_pci_suspend
ehci_hcd: Unknown symbol usb_free_urb
ehci_hcd: Unknown symbol usb_hub_tt_clear_buffer

uhci_hcd: Unknown symbol usb_hcd_poll_rh_status
uhci_hcd: Unknown symbol usb_hcd_pci_remove
uhci_hcd: Unknown symbol usb_root_hub_lost_power

All of this information actually appears multiple times, but I doubt that's relevant.

Doing some searching on errors like this, turned up this link: http://bbs.archlinux.org/viewtopic.php?id=18762 . The solution from that thread is just: "[solved] heh, guess it helps to have /boot mounted when you update the kernel eh? doH!!" That isn't what happened with me, but it does sound related to kernel modules. From rc.conf:

MOD_AUTOLOAD="yes"
#MOD_BLACKLIST=() #deprecated
MODULES=(e1000e ath5k ath_hal ath_pci wlan snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd snd-hda-intel soundcore acpi_cpufreq cpufreq_ondemand cpufreq_powersave !snd_pcsp !pcspkr dm-crypt aes-i586)

Thanks a lot for trying to help me out.

After reading that last post I decided to check out my /boot/grub/menu.lst and see what was going on. It turns out that I had added some kernel argument when I was trying to get gensplash working. I had changed initrd back to normal when I was done with it but had forgotten to remove the kernel argument (I think it was just "theme:darch"). After fixing this lsusb worked fine and I was even able to get my webcam working!
