Latest flashrom update compatible with BVision installed. Not 0x0 libraries. Even reflashed to be sure.
And you haven't even bothered to try to install the software libraries? I'd still suggest you to try it out, but it's of course your choice.
Even though it should be on the flash rom of the BPPC, I have never been able to get a stable installation without installing the software libraries, so I would suggest you to at least try it out. At least you can rule that out afterwards.
A very recent experience (two days ago); I couldn't get my CVPPC working on my CSMK3 with latest pre G-Rex flash. After installing latest software libraries, the CVPPC were fully functioning, and have been since.
