Well....I've really done it now, as a possible fix for my 2i2's sound issue, I thought that I would try uninstalling and then re-installing the device drivers for the usb ports on my Acer laptop.....unfortunately that has just made things worse rather than better....the usb ports no longer works, the usb mouse no longer works, the touchpad on my laptop no longer works, and I can't do a clean install of Windows 10 to fix it cause there's no built in DVD drive, I only have an external usb DVD drive but can't use it cause the usb ports don't work all I can do is press the power button to force a hard re-start.....a $1700.00 laptop has just been rendered useless by my mistake.....well seeing as I've had so many technical problems with all my music gear and computer gear, I've decided to quit trying to pursue a music career and just do nothing for the rest of my life from now on...no more guitars, no more playing music, no more trying to create music, I've spent $1000.00's on getting gear together that just constantly has problems, so, so long everyone.....
