I got a brand new U3 straight from Bitmain over amazon. Have been fiddling with it all night and can't seem to get it recognized by CGminer. I have done all the steps and don't know what else to do? Any ideas would be helpful.
My zadig says the Driver loaded on "CP2102 USB to UART Bridge Controller" is WinUSB (v6.1.7600.16385)
I downloaded CGMiner 4.9.0 and made a notepad file with this in it...
cgminer.exe -o us1.ghash.io:3333 -u DebitMe.U3 -p 123
and saved it as a .bat file in the cgminer folder.
My Devices and Printers folder shows the unit as "CP2102 USB to UART Bridge Controller"
When I start CGMiner it says "No Devices Detected"
What am I missing? It seems to be recognized by my computer, but just not by CGMiner.
Maybe start CGminer THEN plug the USB in

That's how CGminer worked for the little gridseeds,at least for me

Yeah that's one option, apparently hotplug has a better chance of detecting devices. Are you plugged in via USB 1.1, 2.0 or 3.0? Are you putting it through a hub at all?
Ok, I can try that when I get home. I have tried it on my main desktop through USB 3.0 and 2.0, then on my little netbook that I used to run all of the AsicMiner USB devices, which should be 2.0. I am not using it through a hub, I can try that too as well though.
