Did you install the libusb driver for cgminer using the Zadig tool?

yeah... I've seen that thread already. It shows only cgminer and...I cant get cgminer to work at all with this board in minepeon. I need the switches for bfgminer to overclock it and control fan speed.
it shows up as hfa under devices in bfgminer.

I just got one of these cards(the ones with 4 pci-e power connectors) but, I need a little help with the command switches to get it running faster.
I found these settings for the 512 board in the old VMC thread:
cgminer.exe --hfa-fan 100 --hfa-hash-clock 720

I am using a Pi with the latest version of minepeon. If I use the default cgminer settings in minerpeon the board just keeps cycling power every 10sec... If I use the default bfgminer settings, it hashes fine at around 220gh and temps stay low at 69-70c, very stable.   Are there recommended clock settings for this board?  can I use --hfa or another switch with bfgminer?

I would like to figure out how to set fan and clock settings using bfgminer if possible, or if not, how to get cgminer to work.

It's connected to a Seasonic x-850 power supply and a CoolitSystems water cooler.
