usb connection issue [help]

So my wife note 4 (sprint) is stock (6.0.1) and works great except for it will not connect via USB to my windows 10 PC. Device manager shows:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.
I would like to root in order to debloat but cannot connect to the PC in either download mode or just on.
I have tried installing Kies and drivers also I am using the original USB cable with no hubs.
Try another cable and another USB port.
It could be the on device micro usb socket. This type of socket is pathetically fragile and does have a high failure rate. I have seen this issue time after time...The older the device (and let's face it, the N4 isn't exactly the current flagship) the more often this port is the culprit.

Computer not recognising Lenovo K30-W

I have a bricked Lenovo K30-W I'm trying to fix (freezes on startup). My computer (Windows 10) won't recognise it when I connect it to the USB port. In device manager, the phone is displayed as unknown, with error "Device descriptor request failed". I tried connecting to different USB version ports, I tried installing multiple different drivers and software, but nothing helped. Adb doesn't recognise it as well, even if I boot the phone to fastboot with volume+power buttons. Any other ideas? Thanks.
Update: problem seems fixed. I used another USB cable and plugged it into an older version USB port. It is now recognised.

Device not recognized error

Whenever I plug my phone into my pc I get this error. I tried 3 different computers and 4 different cables. I installed the Samsung usb drivers and adb drivers and I still get the error. I've had some people tell me the problem could be the cable, the charging port on the phone or the motherboard. What's wrong and how can I fix it?
Hi can you please provide more information on your issue like the specific error message??
