hub 1-1:1.0: unable to enumerate USB device on port 2

I recently installed Arch on my Sony Vaio laptop. The thing is I am always bombarded with these messages right through the installation and even now.

These messages keep overflowing in my tty screens.

From dmesg:

[  351.463291] usb 1-1.2: new high speed USB device number 115 using ehci_hcd
[  351.476781] hub 1-1:1.0: unable to enumerate USB device on port 2

[  353.523021] hub 1-1:1.0: unable to enumerate USB device on port 2

During my installation I had to rmmod the echi_hcd for it to stop, but right now what should I do? I read in my couple of posts loading the ehci_hcd before uhci_hcd should solve it but it didnt. And I believe the usb device is a internal device or something because I dont have any usb device connected at the moment.

There was a recent mkinitcpio change related to USB -> https://bugs.archlinux.org/task/25788
Perhaps try to update your system (-Syu) and rebuild the initramfs with 'mkinitcpio -p linux'.

Sadly, that didnt work. How do I find out what device is causing this.

Looks like the only device not working on my laptop is the Webcam

EDIT: Is there anyway I can get my webcam to work. I believe these messages are related to my webcam.
