By the way I think Con did incorporate exactly those changes into the mainstream cgminer (I think as of version 3.11 everything should be stable, he also added a speed override option)
Hrmm. I didn't see any references to this patch in the main branch, which is why I created my fork (
https://github.com/utdrmac/cgminer).
If I clone ckolivas's main branch, and compile, I have to use hidapi and I get hardware errors or I get no detection of NFY at all.
Using my fork, with the patch from technobit, there's no need for hidapi (known to be cumbersome with RPis), YellowJackets are detected, run more efficiently and produce 0 hardware errors.
Excuse me? I'll give you the benefit of the doubt and assume you're mixing up my code with something else. There's no code in the master cgminer code that uses hidapi, nor was there any code that used it. It only uses libusb directly which is included in the cgminer source, for that is the driver model for all usb devices in cgminer.
