Resolving 'No valid local video devices were detected.'

We require a Bluecherry (BC- series) analog capture card if you plan to connect analog cameras.
This message means either the driver is not loaded, or a BC- series card is not detected. Make sure that you installed the solo6010-dkms module. If you haven't, you can run this command:
sudo apt-get install solo6010-dkms
Verify the driver is installed
Run this command:
dpkg -l solo6010-dkms
The output should show the current version of the driver as shown above.
Verify your capture card shows up in lspci
Verify that the card is detected in 'lspci'. Running lspci should show a Multimedia video controller:
curt@blackbox:~$ lspci |grep -i video
04:05.0 Multimedia video controller: Bluecherry BC-H16480A 16 port H.264 video and audio encoder / decoder
If the card shows up here, then restart the computer to see if the devices now populate in the setup interface.
Reinstall the driver
Currently there is a bug in the driver that causes a new module not to be built when a new kernel is installed. This will be resolved in 2.3.8 of the driver, but for now you can run this command:
sudo apt-get install --reinstall solo6010-dkms
Comments
I had the same problem, but got it working differently.
1. My driver was not the same version:
$ dpkg -l solo6010-dkms
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Description
+++-======================-======================-============================================================
ii solo6010-dkms 2.4.0-1 Softlogic 6010 Video4Linux MPEG-4 Encoder/Decoder support
2. My device didn't show up exactly as described, but was visible...good enough.
$ lspci |grep -i video
02:05.0 Multimedia video controller: Bluecherry Device 5310
3. The module wasn't loaded, and didn't exist in the /lib/modules tree !
$ lsmod | grep solo6
$
$ find /lib/modules | grep solo6
$
4. Turns out I had to build the solo6 driver after dpkg it.
$ cd /usr/src/solo6010-2.4.0/ && make install
5. Would not load due to symbol resolution issues.
$ sudo dmesg
6. Had to explicitly install the dependent modules specified in
cat /usr/src/solo6010-2.4.0/solo6x10.mod.c | egrep '"depends'
sudo modprobe videobuf-core
...
Got it running !! Now I have to see if the above steps are automated for after a reboot. Any pointers would be welcome as to better ways to how I solved it.
Forgot to add, had to signal the bc-server with USR1 to force a reload/restart.
Found more time to play with it, and all I need to do at step 6 was this:
sudo depmod -a
I still need to ping the bc-server to re-poll the video devices because it seems the module loads after the bc-server starts, so there are no devices. So I just needed to add this to a late init.d routine. (Or you can manually do it with sudo)
kill -USR1 $(ps -efw | egrep '^999' | awk '{ print $2}'
I added a bug for the server process here: http://improve.bluecherrydvr.com/issues/1066
