Fast track is unknown device

[sunka_killer]

Hi guys. I have a really unpleasant problem. I own m-audio fast track. It's connected to my mix and to PC via USB. I have Win10 64-bit laptop. Everything worked as it should, but one day, my PC wasn´t available, and I needed something as a power supply for the fast track. I connected it to my phone by USB reduction. The next day morning I wanted to connect it back to my PC (to record some audio) and it didn´t work! Windows was telling me, it´s the "Unknown device", so I got scared. It looks like the USB is no more full USB (file transfer cable), but only like a power supply cable. I reinstalled drivers, changed USB port, tried another cable, also I connected it to another PC. Nothing worked, still, it´s unknown device. So I went to the internet, read everything a little bit similar to my problem, but it was useless, and I couldn´t find my exact problem. So, dear forum, you´re my last chance. Please, anybody something, that could help me?
