No not really. It's a problem with the epiphan driver. I guess you use a
non english version of Ubuntu... At one time the v4l or the vga2usb
driver switched to localized error messages. This should be fixed at
least in 1.2 I hope (although I'm not 100% sure).

[1] This is a sort of a nickname for the piece(s) of code that
(allegedly, as it turns out) fixed the problem of plugging/unplugging
the cable in the Epiphan cards.

Hello Adam,
I know this is some time ago, but: having driver
vga2usb-3.25.0.2-ubuntu-2.6.35-25-generic_x86_64.tbz installed, I use
the Epiphan DVI2USB Solo with capture.device.SCREEN.type=V4LSRC on the
CA. When I disconnect the cable, recording stops, plugging it in again
changes nothing.
Trying capture.device.SCREEN.type=EPIPHAN_VGA2USB, recording goes on
with a test pattern, but connecting the cable again doesn't bring the
input back.
So shouldn't it be the other way round, as you discribed? Or: how
could
I get scaling/unplugging/replugging features?
Thanks for answering,
regards,
