UMC404HD not getting input from AT2020

[WellThatsJustSilly]

• OS: Windows 10
  Audio Interface: UMC404HD (connected to computer via USB 2.0)
  Microphone: AT2020 (connected to interface via XLR male to female)

Hi there. I have fiddled with this for a few hours and have had no luck. Audio output is working fine, I am listening through headphones connected to the UMC404HD's headhphone jack. But neither Windows (looking at the input monitor in Sound > Recording) nor Audacity seem to be able to record any input from the AT2020 (plugged into input 1, though I have also tried plugging into input 2, with no difference).

Before I continue, here is a picture of the front and back of the UMC404HD, so there is a little less ambiguity in my descriptions. Also, I want to apologize in advance; I am not much of an audio guy, so my knowledge here is pretty limited. Please let me know if I am making any mistakes.

Things I have tried:

• - The XLR is plugged in snugly on each end.
  - Phantom power is turned on.
  - Drivers are installed (found here; I have tried both "UMC Driver 3.29.0 for Windows 7 to 10", and "Windows Driver V2.23.0", same results for each).
  - Gain knob is set in at the middle (the line is pointing straight up).
  - Line/Inst is set to line.
  - Pad is off.
  - "BEHRINGER UMC404HD 192k" is the default recording device; I have disabled all other devices.
  - Levels are set to maximum in Windows.
  - The USB cable has been plugged into 3 different ports on the computer, two USB 2 and one USB 3. The two USB 2 produced fine audio output, the USB 3 seemed to clip occasionally.

Miscellaneous notes:

• - Neither the clip nor signal light for any of the inputs are active/lit. When I turn on phantom power after waiting with it off for a minute or so, the signal light will flash briefly for each input, but that is the only activity I have seen.
  - There is a loud buzzing sound when gain is set to max. This does get picked up by Audacity and Windows, and is reduced slightly when the pad button is pressed.
  - When touching the body of the microphone, a buzzing can be heard that changes intensity depending how much of my hand is touching it. This is audible even at medium gain.
  - When the mic is unplugged, there is no buzzing whatsoever even at maximum gain.

That's about all I can think of. Unfortunately, I have no other audio interfaces, XLR mics, or XLR cables to test with. Any help or suggestions whatsoever would be greatly appreciated. Thank you very much!

No worries guys, my friend Lucas fixed it. Turns out it was a crappy cable.
