Multiple ASICMiner Erupters Windows XP

[maznblue]

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.

bump.
did you ever solve this? I am trying to run 8 erupters but windows only sees 7

I was able to get up to 13 working on WinXP, but it was anything but reliable.  Win7 has worked great for me.

yours sounds like its a hub problem more than likely you hub can only power 7 erupters

This worked for me on windows XP

Had the same problem as you.

WinXP has issues with managing multiple duplicate devices.  Lots of people have issues and I have not seen a definite fix for it.  I have been able to get 8 or 9 working at the same time unplugging, plugging reinstalling etc. but when I went to 11 I was never able to get them ALL up at the same time so switched to win7 and never had an issue with them all running at once since.

the problem is   all the  be's  have a serial number of 001  ,   that link i posted above,  you can download a program  and reprogram the serial number on each BE.    then you will not have hardware conflicts.   To me thats a pretty definite fix.   Once they each have a different serial number ,  windows xp  no longer throws the hardware errors.  


Edit:   I will put step by step instructions on a website  and post it for help

Great thanks for the info I didn't read it all the first time, but a lot of people have struggled with this.  Good to see a resolution.

I have 2 hubs. I am running 5 BES on the one and 3 on the other. The one hub has a power adapter rated at 3.5 amps and the other hub rated at 2.5 amps. So power is not an issue and I am conginesent enough to not overload a single hub.

I will have to concur with the below post although I do not have the luxury of win7 at the moment.

WinXP has issues with managing multiple duplicate devices.  Lots of people have issues and I have not seen a definite fix for it.  I have been able to get 8 or 9 working at the same time unplugging, plugging reinstalling etc. but when I went to 11 I was never able to get them ALL up at the same time so switched to win7 and never had an issue with them all running at once since. 

The problem has really been a "nightmare" and I wasted an entire weekend installing, reinstalling, rebooting, unplugging, replugging...the whole 9 yards. Became this entire OCD like routine. I began pouring into research on Windows Dev on USB's, USB controllers and Hubs.

So long story short, I stumpbed across this program called USBDeview found here --> http://www.nirsoft.net/utils/usb_devices_view.html I learned that a number of devices were showing up as the same device as stated here ->>

the problem is   all the  be's  have a serial number of 001  ,   that link i posted above,  you can download a program  and reprogram the serial number on each BE.    then you will not have hardware conflicts.   To me thats a pretty definite fix.   Once they each have a different serial number ,  windows xp  no longer throws the hardware errors. 

In conclusion, I was never able to get the 8 BES running on 2 hubs to hash on one machine. Even after using USBDeview to unistall a specific BES from my PC's ledger It was still buggy as hell. So after a weekend wasted, I was satisfied to get 5 BES hashing on one machine and the other 3 hashing on an entirely different machine. Im just happy to be hashing and not loosing BTC. Now im afraid to even look at the things the wrong way. The 3 BES that are hashing are still throwing a ton of Hardware errors (3.3%) but it leads me to believe its a hub issue. I will have to check out the above mentioned program of rewriting the serials.Thanks.
