Review on External sound card BEHRINGER U-PHORIA UMC22 by Bhavin Srivastava ᠌

Arrived a day earlier than expected. I connected it to the main computer, not one indicator is off (including power), but the computer seems to see it, started to shaman with firewood, nothing helps, I connected the guitar, there is no signal, generally silence, and in programs for emulating guitar effects came in, and fl studio, the guitar is not visible (for the guitar and took it) Usb ports are ok. I even reset Windows three times, nothing helps. I connected it to a second computer, a note-tablet (on which there is also a keyboard separately with a cover), everything works on it, the signal goes on, but there were also some problems with firewood. Maybe someone understands? Tell me what could be the problem, why the computer seems to see the sound, but there is no signal, and the power indicator is off, that is, the sound with it both works and does not work at the same time .
