Welcome.
First things first we need to know how you are running it. powered hub or non-powered hub? Where abouts is the voltage dial set? What freq have you got it set at? Pictures would be useful
Of course... and thanks for the welcome
I'm running it from one of the USB ports in the back of my HP Proliant Linux server. The voltage dial is set on factory settings; I've tried a half clockwise turn up and also down, but returned to (more or less) factory settings. Hard to tell what it is actually set to, how do you tell?
I had it running at clock 230.
Not sure how to post a picture here.
Thanks for your time!
most likely your error message is from the usb port being overloaded and turning off and back on..
on a stock non powered usb port (the ones on the back of a computer), you will have a hard time getting above 150M.. which is around 8.25ghs.
you said it was running at 11 ghs.. that is around 200M.. which is more than 600ma probably around 750 or 800.. 900ma or so is 225M..
you can either get a good powered hub that can do 1a per port, or you can try to lower the speed to 125-150..
OK, good, thanks for the tip. I did get to 230m for about a full day, but I understand this should not really be possible with the 500 mA that the port provides at best.
Lowering the speed to 150m over the non-powered USB does not help when running cgminer again; the stick does not respond. The white led is continuously on (no green, no blinking). Errors that I get are
COMPAC 0: No valid hashes for over 10 secs, attempting to reset
COMPAC 0 attempted reset got err:(0) LIBUSB_SUCCESS
...
COMPAC 0: Device failed to respond to restart
COMPAC 0 failure, disabling!
Any tips welcome...
