Edited this post out - The developer of this software already saw it so no need for it anymore.

How do you accomplish system wide knowledge of usb devices? Are you writing a file somewhere or in shared memory somehow?
Ps I thought a mod split the thread but I guess not lol
Yes a file and shared memory on linux, and a named mutex on windows with the device name based on the usb bus and device address.Ps I thought a mod split the thread but I guess not lol
A mod got rid of some trolling and associated discussions, but the troll does not stop stalking this thread and reappearing.

Because the instances do fail at finding the devices when they count to usb whatever even though they should already know.

Yes reliably. Will post tomorrow. It gets tiresome using rdp on my phone.
No rush. We greatly appreciate the debugging but take your time. This is the unfortunate cost of such heavy development, and we're heavily dependent on users testing scenarios we can't reproduce ourselves. June 02, 2013, 11:58:38 PM

About 5-10% better still over 60%
Also I have problems with 2 instances. Running the 17 fpga instance before a 3 crashes the 3.
Well I don't think that's the cause then if it's only 5%. We'll investigate further. Meanwhile, if you're reliably getting a crash, can you use a debug build to see what crashes?Also I have problems with 2 instances. Running the 17 fpga instance before a 3 crashes the 3.

The instructions for getting a debug output are in that directory. Thanks!

to see if it makes any difference to CPU usage please?

3.1.1 used very little and confirmed it by seeing total cpu usage.
3.2 looks like its using 50% by itself with another 20% by system interrupts or drivers of some sort
Windows normally uses low resolution timers and perhaps it's related to us trying to use high resolution timers with these new drivers. Can you try one of the .exes in:3.2 looks like its using 50% by itself with another 20% by system interrupts or drivers of some sort
I just noticed, cgminer 3.2 uses massive CPU. I'm runing 20 lancelots and cgminer is using over 70% on a i7-3770.
What did 3.1.1 use, and is there a way on windows to see what system time the (ftdi) driver is using? The CPU usage of drivers is often hidden from you.http://ck.kolivas.org/apps/cgminer/temp/

Also, cgminer 3.2 does NOT work if I 'su root' either. I don't think it is the permission problem.
USB3 ?How do I check?

It isn't showing a permission issue now - ttyUSB0 is removed when cgminer starts and cgminer 3.2 doesn't find any devices to mine with.
If I start cgminer 3.2 and then plug in the miner afterwards it is disconnected immediately and cgminer doesn't see it.
Not that this is the cause of your problems, but it's worth nothing that ttyUSB0 is being removed by 3.2.0 because cgminer doesn't want that driver there any more, so it being removed is normal. If I start cgminer 3.2 and then plug in the miner afterwards it is disconnected immediately and cgminer doesn't see it.

Got it working!
I went back to cgminer 3.1.1 and used the -S option to tell it where to look.
I'll play with the other settings now and see if I can get it running without root, etc.

LINUX:
On linux, the direct USB support requires no drivers at all. However due to
permissions issues, you may not be able to mine directly on the devices as a
regular user without giving the user access to the device or by mining as
root (administrator). In order to give your regular user access, you can make
him a member of the plugdev group with the following commands:
...
Read the rest
Edit: there's a bit about "sudo cp 01-cgminer.rules /etc/udev/rules.d/" further down to complete the solution to solve permission problems
As I said in a later post I have set the udev rules so that the USB device is owned by the plugdev group (and I'm in plugdev as well).
My later post has some more details with the --usb-dump output:
