I have a samsung laptop, model number NP350E7C-A01US. Every time I insert anything into one of my four USB ports, I get the error: "USB Device not recognized".

You can see the laptop here: https://www.samsung.com/us/support/owners/product/NP350E7C-A01US

    No worries, I fixed the problem :) I went through a ton of stuff and then plugged it into a different USB port and it worked.

    How are you trying to connect? The windows network UI or the netgear wizard. If you look in device manager and in Networking does the device show up? Windows key + x > networking see if there are multiple wireless adapters and disable the extra one if there is another active wireless. There should be a icon that shows device status in the netfear tools or on the desktops

    Were you able to run the keyboard strat from the exe?

    Try dism /online /cleanup-image /restorehealth to see if that helps.

    what happens when you open a notepad and hit windows key + S does it type an s or do nothing?

    I found the ram test that I spoke of earlier. I don't know why I couldn't remember it but someone posted it and I grabbed it for you. I did it earlier and saved it to a file but forgot who posted it so I can't give them credit. This will tell you if you have a RAM issue so you can get a better idea if you need to contact support to try and get them to send you some new sticks or warranty the repair out locally if you are lucky, and you don't have to open the PC :)

    First run Memtest86+: 

     This runs from a boot disk or CD and should eliminate or confirm if one or more of your memory

     sticks are bad or the SPD values in the BIOS are correct.

     Let it run for as long as you can: 2,4,6,8 or more hours (at least 3 full passes), if no errors by then your ram is OK.
