Steinberg UR22 mk2 flashing light

Good day everyone.
I have a some problem with my device. I was using it without any problems, without counting random disconnecting, until yesterday it had fallen down on the floor from the table and since that my computer don’t recognize the card.
The usb diode keeps flashing constantly, which i thought means not enough power is given, but I still can hear guitar sound from the input channel in headphones, it’s a really strange. Also I’ve tried 3 different cables to make sure the old one is not broken, but still no results.
I hope for help from someone who had the same issues and solved them.
Or is it out of use? I hope it isn’t, but I guess so.
P.S. Isn’t it the digital device? So where is no way to mechanically broke it, since where is nothing to shatter or wreck. Or am I wrong?
P.P.S. I’m not native english speaker, so sorry for my grammar.
