I have one problem when trying to run the Drillbit8 board on the same pc that runs the Drillbit Thumb - can't get 2 separate instances of cgminer to run with separate settings for the 8board and Thumb. The 1st instance 'captures' both devices and the 2nd instance is left with 'nothing'. Does anyone know how to convince cgminer to run a single device out of a few similar ones? (on Win7). Both are seen by device manager as 'thumb', the only difference being in the detailed properties where the hub/port are listed, but I don't know how to apply this in Cgminer.

This is necessary if you want to run non-stock settings, which are different for each. If I run them both in 'stock settings' there is no problem (other than the Thumb getting quite modest hashing rate).

Managed to run 2 separate instances of cgminer using the --usb :1 addition to the batch files calling up the Thumb and the 8Board. Now the Thumb can have its different setting and the board its unique setting.
The single board is connected to a spare PC power supply, the 4 pin Molex powers the board and the USB connector goes to the controlling PC. A small fan cools the heatsink side. My board came without the small heatsinks on the MosFETs (QF1 - QF3) which are getting quite hot. I tried some overclocking, but now wound it back to stock settings as I feel that it is getting too hot with the present cooling arrangement.
