If you got it to work with BFGminer then you must have at least the CP210 drivers installed, I guess.
For CGminer you will need to run Zadig. If you did, have you tried to restart the machine? I remember having had troubles there in the beginning as well.
And make sure you use cgminer from the github repository, not the "regular one", but I guess you did that?
PS: they take some time to come up to speed.
I tried the Zadig for cgminer and rebooted etc but still wouldn't see the U1 so that's why I resorted back to bfgminer because you can add it manually.
