I'm running a Dell Inspiron 7720 Laptop with Windows 10
My problem is this: Yesterday my computer installed an automatic Windows update. That night when I went to plug in my iPod Touch, none of the USB ports recognized the device. It didn't show in My Computer, didn't charge, nothing. Finally, after over an hour of research, I updated the drivers and was able to get it working.
Today, I tried to use a simple Lexar 16GB USB 3.0 thumb drive. It's a drive I've used many times before on this computer and others. When I plugged it in, the computer will not recognize it, in that it doesn't show up on My Computer. I plugged the drive into all my laptop's USB ports, it still didn't work. So then I plugged it into someone else's computer and it worked fine. I reformatted it on their computer, but it still didn't work on my laptop. Then I tried plugging other smaller usb thumb drives into my problem laptop, and it recognized them.
When I went to the device manager menu, I noticed that there it had a listing for the Lexar thumb drive when it was plugged in, so at least part of my computer can see it. When I right clicked on it and tried to update the drivers, it said they were up to date.
I tried to do a System Restore to before the Windows Update, only to find out that Windows 10 has System Restore turned off by default, and so I had no restore points.
My main PC is currently broken (I have another thread about that ordeal in fact), so this is extremely frustrating for me, in that I need to use this, my one large USB drive, to try and fix the other computer. What can I do? Thanks
