USB Block Erupter showing up as generic USB Device instead of "Port", won't mine

[PortablePlatypus]

I've been mining with two USB Block Erupter Sapphires without issue for at least a week now, properly cooled. Today, I've been messing around with things trying to get my Antminer U2 up and running and must've done something that now causes one of my erupters to show up under Device Manager as a usb device instead of under "Ports". When I try to mine with it, it just sits in standby doing nothing. However, if I plug it into my Win 7 machine it comes up normally under "Ports" instead of "Universal Serial Bus Devices" but I don't have an ethernet to that box to test if it will mine. I'm not sure what exactly is going on with this stick. Is it fried?

Maybe you installed a WinUSB driver?

Is the problem on a windows xp machine?  This may be a device identifier issue.  I've never seen it with 3 devices, but I suppose it is possible.  There is a fix posted in these forums somewhere and if I have time to dig it up for you I will, but if you keep restarting and plugging it back in to different ports it may eventually pick up properly.  Windows XP doesn't handle duplicate usb devices very well.
