I have installed ubuntu 15.04 on my Acer aspire V15 and everytime I boot my system up I get the error mentioned above for about 10-20 seconds then another black screen with some writing then it boots up normally. I have search the internets for a solution but have not found anything even the least bit helpful.

When I run the command dmesg | grep -i usb I get this with the error inside
