Hi, I have 16 ASICMiner Erupter USB 330MH/s Sapphire miners plugged into 3 different D-Link Hi-Speed USB 2.0 7-Port Powered Hubs.  No matter what I do I can't seem to get them to all work at once.  Everytime I plug them in I get an error message stating that some of the devices can't be used because there are duplicate device (Error Code 42).  I have rebooted, re installed the device drivers and it doesn't seem to fix the issue.  The other weird part is it is not always the same ones or even the same amount.  I am running windows xp on this machine.  

Also, I have a Windows 7 pc and it seems to run fine on that but its not an option to run it on this machine except for testing so its somthing with XP.

Any help would be appreciated.

Thanks in advance,
Marty

Hi, I just purchased my second ASICMiner Erupter miner and I am running into problems.  I already have one working but when I plug the second one in I get the following error:

                       'Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system (code 42)'

I have tried re-installing the drivers from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx and rebooted several times but I can't seem to get two working.

Here is my setup: 
Machine: Windows XP Laptop
Miner: bfgminer
Start Up Command: bfgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u XXX -p XXX-G -S erupter:all --icarus-options 115200:1:1 --icarus-timing 3.0=100

I am just plugging these miners right into the USB ports on the PC and they both light up with a green light when plugged in.  Any suggestions would be great, currently I have the second Miner plugged in and running on my mac fine but I would like to have 5 or 6 of these all running on my Windows machine.

Thanks in advance.
