Hello everyone! I just got this laptop with a pretty bad problem and i want to see if anybody had this before.

My usb ports arent working as they should. They do read usb sticks and wireless mouse, but any wired mouse will get the "usb device not recognized. the last usb device you connected to this computer malfunctioned and Windows does not recognize it". I have tried like 6 methods to solve this (drivers uninstall, troubleshooting, usb change selective suspend settings etc) but nothing worked. Ok, no problem. I can live without a wired mouse. Now it gets funny. I wanted to reinstall the windows with a usb stick, but there is no usb option in the boot menu. the usb is completly inexistent. 

I took the laptop to some local service (its out of warranty) where they have tried different OSs and fixes, but nothing worked. They've told me the usb ports are completly irreparable due to a previous failed bios update, and even changing the physical ports wont fix the problem. Is this a thing? Did it happen to anyone before? I've browsed lots of forums and topics but couldnt find anything simillar. 
After all, I don't mind installing a windows with DVD and not having a wired mouse; i just want to know if the guys on the service are right and theres nothing to be done. Nothing else seems broke to the laptop.

Thank you and sorry if im in the wrong section!
