I just go two U2's but I can only seem to get one running... not using a hub, direct port off the WinXP laptop like I did with my BE's these replaced.

Any help is appreciated, using CGMiner 4.2.2

Either the driver did not install correctly on that miner or you have a DOA, unfortunately I have seen all to many of these new ones DOA. I have handled 8 that looked as though the component labeled 4RU was totally burnt/fried by the solder work at the factory.

Thats just it, both work fine because I can run either or as a single but when I try to use two at the same time I get the previously posted output.

I remember something similar with my BE's but I ended up getting them working somehow.

Try starting with only one miner installed in the laptop, let it stabilize, install the second miner and wait long enough for windows to assign the right driver. I've seen windows change COM# after it realized you have two of the same devices, not sure why, but it did this with a set of USB web cams I had a couple years back. Then try to "Manage" adding the second miner to the already running instance.

So what, like start CGMIner let it run for say 10 mins under 1 stick then add the other ?

When I goto the add hardware thing and look or the silicon labs thing and click it I ge this...

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

Gonna try and reset the laptop see if it helps butt if it doesn't then I guess I'll have wasted my cash on these damn things ;-/

There's your problem. Your 13 year old operating system gets confused when devices look identical to it. Go win7 or just about any linux instead.

I respect the fact of you authoring CGMiner but do you really have to make that childish of a post instead of actually trying to help ?

I think he just did both.

Ok, so whos gonna cough up and buy me Vista, Win 7 or try to each me linux to which I dont understand a single damn thing about ?

No one, wow who'd have thunk it... ok so back to this XP thing !

There are entire OS distros geared towards mining.  I'm sure you could manage with very little research.

Sounds like a great learning opportunity

so back to this XP thing !

Have you read through this thread?
https://bitcointalk.org/index.php?topic=270367.0

From some quick googling, the U2 seems to use a CP210x chipset.  I have no idea if you can reprogram the ID of the U2 with that tool, but if you can, that 'should' do it (see plenty of other posts about it working but being unstable when plugging in a whole bunch of miners).

That said... XP is EOS - even if you get it mining, you might want to consider how hard people are going to start knocking at your machine with exploits.  Go grab a Ubuntu or whatever 'live CD' copy, drop it on a USB stick (or CD/DVD if your machine won't boot off USB), and give it a try.. can't hurt.

Goin on that idea, I would need a second working system which I don't have or replace the system on the existing laptop which isn't just for mining but my every day use.

So ATM, it's XP or nothing... unless someone has a Vista CD they can send me a copy of. I have a Vista key for this laptop.

It's about 6 yrs old but I originally replaced the OS with XP and it never did come with a Vista CD.

Download the same version of Vista on piratebay and use your key.

Vista Home Premium

Seems I "must" download a torrent client to use pirate bay lol

Just my luck by the time I get done I'll have so many problems the laptop would probably be better off smashed.

   I don't know about piratebay  but I seem to remember Microsoft recently made downloadable versions of OS available thru its own site but your going to have to have a Microsoft ID like Hotmail/outlook whatever and sign in. Then read the instructions you may need a specific version of image burner to make your own Vista cd-rom or install it on a flash drive.
   The other option is to figure out how to use the FTDI Tool Kit from SiliconLabs to assign the devices unique serial numbers that XP won't have a fit over.
   OR...................consider that Ubuntu can be installed on a flash drive/burned on Cd-Rom and will run without removing XP. A learning curve will follow but it is a viable option, just not your preferred one. I tried Linux and it wasn't for me, but I'm not knocking the next guy who says he likes it, till he says the wrong thing, then he better start looking for a new barstool with intention!!!!!

I actually did DL that tool for the fun of it but when ran, nothing showed up in the device list.

As for the Microsoft thing, I do have a hotmail account but I've never heard of them having downloadable OS's.

[hurricandave]

 It came about when they decided to release Windows 8.1 free preview, so many people had used the same method with the free Windows 7 preview that they decided to make the recovery OS available for people who needed to switch back to the original OS because their hardware wouldn't run the upgrade and they couldn't find their back up.

Offtopic: What on earth was childish about it? It was nothing but factual.
