Hope I am in the right forum.

I just upgraded to BFGMiner 3.3.0 - notes say GPU disabled by default. I cannot mine with my vid cards, using Win 7 64. I have -S openCL:auto in my startup.

real question I have is this, My Erupter's all come up fine and mine, but I get message shortly after startup:
 [2013-10-26 01:53:24] ICA 0: Seems too slow to be an Icarus; calibrating with short timing

they get up to correct speeds, I was just wondering what that short timing notice is about?

I just upgraded to BFGMiner 3.3.0 - notes say GPU disabled by default. I cannot mine with my vid cards, using Win 7 64. I have -S openCL:auto in my startup.

Seems pretty clear to me - GPU mining is disabled.  That means it's not enabled.   Huh

real question I have is this, My Erupter's all come up fine and mine, but I get message shortly after startup:
 [2013-10-26 01:53:24] ICA 0: Seems too slow to be an Icarus; calibrating with short timing

It's normal.  The Erupters run on Icarus protocol, but are slower than a real Icarus, so BFG is just adjusting it's speed to suit.

flags for USB Erupters should be

Code:
-S all --icarus-options 115200:1:1 --icarus-timing 3.0=100

This should fix your timing issue

No. Don't do this. This is a very old option and is not recommended. If you are using asicminer block erupter usb, use this much more simplified code. It will detect the correct speed without needing to estimate it.

Code:
-S erupter:all

Something wrong with your USB drivers - you should be able to run all those together no problems.
