Sorry you have some misconceptions about the effect of mining at different difficulty so let me clear them up once and for all: It makes no difference to these devices what difficulty you mine at in either hashrate, hardware error rate, or reject rate.

If those random hardware errors cause the entire current work unit to fail, then it's best to keep their effect to as small a portion of work as possible.  

Let's pretend that work diff of 64 takes about 10 mins, on average, to produce an accepted result.  If you have a single hardware error in that 10 minutes, you wasted the entire 10 minutes.  If you had broken it up into 8 units of 8 diff work, you would have only lost ONE of those work units, not all 8.  Instead of losing all 64, you get 7 of the 8, or 56.  56 is better than 0, yes?

And if you're churning away at solving a work unit diff 64, and only make it to halfway (32) before a block is found by someone else....you just wasted the progress you did have (32 -- which is 'halfway'), since you can't carry that work over into the next block.

I was basing it off of what I was witnessing with my fury in bfgminer 3.5.1.  3.2.0 doesn't report the errors.  Neither does your cgminer, as well you know.

There may be some sanity checking that allows partial recovery on a HW error, but I wasn't seeing it in bfgminer 3.5.1.  I saw much lower effective rates as I increased the work unit's diff.  And yes, I let it run long enough.

The hardware mines at diff 1. Everything else to do with diff is done outside of that so it makes no difference to how the hardware performs. Anything you're seeing is pure luck and variance related. There is no "progress" or anything else that matters. Every hash is a single hash. At diff 64 you find 64 more when you find a hash good enough, but you lose 64 on a reject etc. It all evens out in the end. If you believe anything else then you're just misunderstanding how this all works.

Tried 4 times still the same thing going on and not working.

Unzip the package in the same directory that windows downloads it to.
Then copy the ini file to your desktop.
EDIT:- or root of your c drive
My system could not install the driver from more than 3 branches deep in the driver update tree.

You could maybe try the download from here, it worked for me:

https://bitcointalk.org/index.php?topic=319419.msg3467670#msg3467670

Got one working on the Win7 box, cleaned up the zip file for installation. By cleaned up I mean I removed the 'Encrypt these files' option, so you could use the driver properly. Also removed the _MACOSX folder which had windows binaries in it. Not to mention, it's not on MediaFire (which since that is a fresh Win7 install it didn't have flash installed causing Chrome to loop-crash due to trying to forcefully install flash, thanks mediafire... you suck).

If anyone wants the cleaned up zip file: http://256mining.com/downloads/bf1_bfgminer_win7.zip & use the directions on on this thread after downloading.

Good luck.

What windows version is it?

Win8x64 has never worked with erupters for me. I keep trying every few weeks, its a pile of s...

Win7x86 works first time every time, apart from the driver update(so installed as above)

It is the same PC with 2 drives, so its not hardware.

Windows 7 x64 and I have normal eruptors all working fine. Even taken them out uninstalled all drivers related to them to try getting the blues working and still no joy

Fair comment, also need to install drivers with admin privileges.

funny you should say that I have everything running on an admin account I might as well not of bothered to even of got these stupid usb sticks. If anyone want to buy them feel free to drop me an offer on them in hand and working on cgminer however will not work on bfgminer. I know a lot of work has gone into making them but tog et them working is a nightmare and costing me each hour theri not working.

Then just use cgminer? The performance is tied to the device, not the software...

cgminer is only giving me 1.2 to 1.3GH per device not happy when their meant to be a lot better than this.

What does the pool report? that is the figure that pays you.
The software should just work. or not work.
If the figure at the pool is also low, then its either the hardware or your network.

The pool is reporting  around the same. Am getting to the point now of just selling them. I spent half a day on this BS and am getting more and more pissed of at them the longer this takes. If I don't sell on ebay I might even take a auction hammer to them myself and smash them up. Shit like this does not need to be complicated it should work from the get go without these problems.

Chill for a bit,................. then do you have access to a Pi?............

MinePeon is working ok here.
