Are all ImagingSource cameras supported?

[cmarmo]

I'm trying to install a DMK31AU03.AS under Fedora20 (kernel 3.13.6 64bit).
When I plugged it in the device is detected (the following lines are from dmesg):

[ 4.243080] usb 1-5.4.4: new high-speed USB device number 5 using ehci-pci
[ 4.329954] usb 1-5.4.4: New USB device found, idVendor=199e, idProduct=8101
[ 4.329960] usb 1-5.4.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 4.329963] usb 1-5.4.4: Product: DMx 31AU03.AS
[ 4.329966] usb 1-5.4.4: Manufacturer: The Imaging Source Europe GmbH
[ 4.329969] usb 1-5.4.4: SerialNumber: 31310375

I have successfully compiled and in installed code from tiscamera/src/ and followed instructions from the wiki (https://github.com/TheImagingSource/tiscamera/wiki/Getting-Started-with-USB-Cameras)
But the command
$ sudo ./euvccam-fw -p
failed with the error message
Device not found.
(/dev/video0 doesn't exist).

Are all USB2 ImagingSource cameras supported or we need a specific firmware for DMK31?

Thanks for your help (and for your code!)

Hi,

The camera you have should already have a uvc compliant firmware.
You should be able to add the camera with a command like:
echo "199e 8101" | sudo tee /sys/bus/usb/drivers/uvcvideo/new_id

This will tell the uvc driver that it is responsible for the device and should be all you need
to get /dev/video0.

I will write a udev rule so that this step will take automatically.
I will also modify the instructions to include that information. Sorry for the confusion.

Please let me know if this fixes the problem.

Hi,
thanks for your answer!
It looks like I haven't the uvcvideo directory in /sys/bus/usb/drivers/ ...
Maybe I skipped some installation?

[TIS-Edgar]

Is the uvc driver loaded?

lsmod | grep uvcvideo

If it is not try a
sudo modprobe uvcvideo

[cmarmo]

uvc driver is loaded now... :)
/sys/bus/usb/drivers/uvcvideo/new_id contains 199e 8101
The command ./euvccam-fw -p still answer Device not found.

Let me understand how to enable uvc driver at boot and I will try a reboot...

[TIS-Edgar]

If in doubt always reconnect your camera.

I just pushed a file that should automatically add your camera to uvc.

You can find it here:
https://github.com/TheImagingSource/tiscamera/tree/master/data/udev

Simply copy that file to /etc/udev/rules.d/
After that a
udevadm control --reload-rules
should reload all rules so that you can reattach your camera at any time.
If that does not do it a reboot will always cause a new rule evaluation.

A firmware update is not necessary for your camera model.
As long as /dev/video0 appears and you are able to interact with your camera
through tools like guvcview or v4l2-ctl everything is fine.

After copying your file I have rebooted the machine (the camera was unplugged), then plugged in the camera.
The command ./euvccam-fw -p still answer Device not found.
But guvcview can capture (before it couldn't).

It works! Thanks a lot!!
