I'm in something of an odd situation here, I don't know what's going on.

I ran through the instructions and had a successful start-up with my shiny new Antminer U2. But then I had to restart my host computer -- basically the desktop crashed, and then I couldn't open any folders.  So I clean shut down BFGMiner, then dirty shut down the host -- had to, whatever killed the desktop also prevented log out. Now, if I rerun the exact same command, BFGMiner can't find the Antminer, it tells me I have no devices. Device manager sees the Antminer ASIC at COM16, but even using M / + I can't get BFGMiner to see it.

I have tried unplugging and replugging the Antminer from the hub, and the hub from the machine. Note: The Antminer ran successfully before, so I don't think it's a problem with hub power.

Any suggestions?

Edit: Never mind... plugged it directly into the computer and it started mining right away. I guess there's something wrong with the hub...
