These are all recent releases from fall 2009, less than 6 months old. The distros are Fedora, Suse, Kubuntu, Debian.
> Result was the same with all; when connecting the OnAir GT I got either 2 or 6 lines in dmesg from the USB stack, depending on the distro. After that nothing, pvrusb2 did not load. I also tested each distro with my HVR-850; dmesg showed many more lines including an attempt to load firmware.
