Kevin Chan commented on MH-7570:
--------------------------------
While attempting a MH 1.1.0 capture agent install on Ubuntu 10.10 x86_64 with
VGA2USB, I encountered an incompatibility with the install_vga2usb script and
the latest VGA2USB driver for Ubuntu 10.10 x86_64 (3.25.0.2) that causes a
not-so-helpful error due to the inclusion of the 'v4l_err_on_nosignal'
parameter introduced in this issue.
>From the install script perspective, all you get is this error:
Failed to load Epiphan driver. Maybe your machine kernel or architecture were
not compatible?
In the /var/log/syslog file, you get a much more useful error:
Apr 20 13:31:29 ubuntu kernel: [ 2985.108757] vga2usb: Unknown parameter
`v4l_err_on_nosignal'
Apr 20 13:33:16 ubuntu kernel: [ 3091.737616] vga2usb: Unknown parameter
`v4l_err_on_nosignal'
Apr 20 13:33:20 ubuntu kernel: [ 3096.165204] vga2usb: Unknown parameter
`v4l_err_on_nosignal'
Apr 20 13:33:25 ubuntu kernel: [ 3100.555871] vga2usb: Unknown parameter
`v4l_err_on_nosignal'
Micah asked me to confirm that the 3.25.0.2 driver indeed did not have this
parameter via "modinfo vga2usb.ko | grep v4l_err_on_signal", which returned no
results.
I have asked Epiphan to compile a 3.26.x version for Ubuntu 10.10 x86_64, but
their (sort of sad) response was the use the old one. I have asked again, so
hopefully their response is more positive the second time around.
I have been able to workaround this issue by compiling and installing the
VGA2USB driver by hand.
This issue should probably be noted in the 1.1.0 CA install docs.
