So, I've got a new pc and I've installed win 7 with no problem, except that it can't detect my usb flash drive to acces the mobo drivers (this is the same usb that i've used to install my windows and I'm using it instead of the dvd provided by the mobo because i don't have an optical drive).

Motherboard: ASRock B150M-DVS R2.0

I tried every usb port, but nothing happens. Please help! thanks! :)

I've reinstalled the windows (following those instruction, as I did before) to see if something changes. I got the same problem- win can't detect my usb;

In the Device Manager> Other devices, the USB controller is flagged. I've never encountered this problem before.
And these are the drivers that I've got. Leaving this here in case I got the wrong ones.

It is not there, sadly. It is listed under the "other devices" tab and it is flagged. If I try update those drivers, I can't find my usb, so I'm stuck in this loop.
