So, this error about usb4-2 (mostly) persists on boot , and frequently oven extended uptime:

First I tried to disable the 4-2 like explained this link (uri:
http://stackoverflow.com/questions/2704 … y-in-linux)
I did the "fix" for the newer kernels obviously (#2 anwser). If I recall correctly, someone had a similar problem in this forum, solved this way. It didnt work for me, after a few reboots and some uptime, this is what happens:

Here, it keeps on disconnecting the 4-2 port and reconnecting the webcam which i suppose it is the same device. Also before the "0" to power/autosuspend_delay_ms, lsusb showed a webcam like in https://wiki.archlinux.org/index.php/As … #Eee_1015B - Now it doesn't
Also, on its previous OS (windose 7) it constantly showed a usb error, even though USB3 driver and webcam driver were installed. That's why I suppose it's hardware problem altogether.
I didn't bother with the drivers, because I don't need the webcam (yet). Any suggestions on how to surpress this message? Maybe I didn't disable the device correctly (or has something changed on the kernel since that previous stackoverflow solution?)? And if not, will installing a driver solve the problem? I will appreciate any suggestion.
