Acer aspire E5-575g53re have installed windows 7 but usb only works before startup.

Hello Ironfly.

Thanks for your time and effort.

I got the same : your system does not meet the minimum requirements....

then i went to device manager and pressed update driver and pointed to the folder, that did the trick and the unit was installed, the usb's are all working fine now

but i got the "blue screen of death" when i tryed to uncheck a box in "bluetooth" and the same thing keeps happening every time i do so.

The bluetooth was not installed before, it was installed when the driver for the unknown device was installed.

here is the results of the whocrashed analyze:
