Hi, I followed: http://mcentral.de/wiki/index.php5/Installation_Guide which produced the below oops, even with the device unplugged...
I found mention of 'userspace_driver' a couple of times in the list archives, eg http://mcentral.de/pipermail/em28xx/2008-February/001235.html
But $ hg clone http://mcentral.de/hg/~mrec/em28xx-userspace2 destination directory: em28xx-userspace2abort: 'http://mcentral.de/hg/%7Emrec/em28xx-userspace2' does not appear to be an hg repository!
That doesn't seem to work.What is the 'correct' driver to use etc, might be good to put it clearly in the wiki ;)
