I tried almost everything and magic is still happening.
I had a notebook (ux42vs) with virus ti connected thru usb cable, and everything worked perfectly
Now i have bought n550jk. It has 2 usb ports on left side and one on right. And this is what i observed:
Usb cable n.1. It didnt work in all the usb ports. Connectng virus through it, gives me "unknown device" message. On old notebook- no problems, everything works fine
Usb cable n.2. Didn,t work in left side usb's, works in right side usb. Connected through usb hub ( virus->cable n.2-> hub->pc) works with one of two ports on left side, and in this one on the right. On old notebook- no problems at all
Usb cable n.3. Work in all usb ports, on both notebooks.
So, only one word is in my head. What the f**k is going on. Could someone help?
