Total NOOB here, so be merciful..
I have built a dedicated BTC machine with several USB PCI Cards to handle 9 Erupters..
I plug in all 9 and they are recognized by the Windows 7 machine. All 9 are listed in the PRINTERS AND DEVICES screen as you can see in this pic:
http://sjfm.us/temp/BTC1.jpgAs you can also see in that pic, I am getting an error message from the BitMinter software..
Now, the weird thing is, when I initially set this up, it worked fine for a couple hours.. I had to tweak it and play with it. I tried to install the OTHER drivers listed in that error message, the FTDI drivers. I got an error message when I tried to install them and then, all of the sudden, everything was working..
I let it run for 4 or 5 hours but then had to shut down to re-arrange the hardware.. When I booted back up, I was back to the problem of it not working. I even tried to re-create the issue by uninstalling ALL the drivers and re-installing but this time, the FTDI drivers installed fine, with no error at all..
The only other clue I have is that, when I start pulling out Erupters, when I pull out a specific one, the Bitminter screen "comes alive" with all sorts of error messages.........

2014.01.28 [06:25] No such port "COM18" ..... and then gives me my login prompt.
It's almost as if the software was "stuck" on an erupter and, once that was pulled, it got "unstuck"...
Any assistance on this would be greatly appreciated.

Additional Info: I get those error messages whether I have one Erupter plugged in or all 9..
