That's odd. It suggests an (off topic) windows related driver problem, or a virtual machine issue. > Starting the Grabbee-HD software gives "No video capture device is > connected!" > Then I realised the USB device has to be passed through the VB interface, > VB-Manager > USB > Add > "no devices available". > > So because Ubuntu doesn't properly recognise the device, it can't pass it on > to VB and XP. I don't think the virtual machines work that way, at least not in my experience. I've always been able to do what you want to do on various platforms. Sorry, I can't really help you debug Windows / Virtual machine issues. > > Is there any chance of getting this going on Ubuntu 14.04 natively? Unlikely. Sigma are generally GPL unfriendly. I've done drivers for this chip on OSX before, mostly as a R&D exercise, so I'm highly familiar with it. The chip is a monster to write for, kinda nasty to be honest - not very straightforward. I think you're out of luck. - Steve -- Steven Toth - Kernel Labs http://www.kernellabs.com -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
