Required Info
Camera Model R200
Firmware Version Not able to get
Operating System & Version Ubuntu 16.04 LTS
Kernel Version (Linux Only) (4.16.0-041600rc2-generic)
Platform PC
SDK Version legacy 1.12.1

I am having problem running my R200 on Ubuntu 16.04.

I am getting this error when I try to run any of the examples:

RealSense error calling rs_create_context(api_version:11201):
uvcvideo kernel module is not loaded

As far as I understand, there is no need to run any patch since the Ubuntu kernel is 4.4+.

The same R200 with the same cable working on the same clone of PC that runs MS Windows.

Thanks!

Hello @HumamHelfawi ,
What kernel notification do you receive when you plug in R200 device ? (dmesg -wT)

Using experimental kernels may be challenging, and you need to verify that uvcvideo is enabled in the kernel configuration - try to run
modinfo uvcvideo | grep version
to obtain driver's info.

If the uvc dirver is available but fails to load automatically, you may try to force it by sudo modprobe uvcvideo (while monitoring the kernel log)

@ev-mp Thank you very much for taking time to write this reply. This is what I got when executing the commands you wrote :

The logs indicate that the uvcvideo that was probed had been compiled with (at least the header files of ) kernel 4.4 and is not compatible with 4.16:

[Prş Mar 8 09:26:10 2018] uvcvideo: version magic '4.4.98+ SMP mod_unload ' should be '4.16.0-041600rc2-generic SMP mod_unload '

Is it possible that you tried to apply the kernel patches ? It also might be a leftover from previously installed kernel in case of upgrade).
The easiest way to rectify it probably by reinstalling 4.16RC kernel to revert the original version of the uvcvideo driver.

Thank you very much! Actually, yes I did run the scripts but I did that after I tried running and failed. However,I will search for a way to revert the original version of uvcvidio since reinstalling the kernel did not work for me.
Thank you again for your valuable help!

Hello @HumamHelfawi , in most cases running
sudo apt-get install --reinstall linux-image-generic linux-image
should be sufficient to reset the modules.
Let us know whether you manage to stream depth with the original driver in place

Hi @ev-mp , After I run the instruction you wrote, I am not getting the old error anymore! thank you very much!

However, the system can not see my R200! when I plug it in and using dmesg -wT:

Hi @HumamHelfawi , the log is not informative as it does not shows R200 enumeration events (neither good nor bad).
Is R200 recognized by the host when you run lsusb?

Hi @HumamHelfawi ,
The error inappropriate ioctl somehow indicates that the uvcvideo module is still not functioning properly.
I suggest to switch back to one of the stable Ubuntu kernels (4.4/4.10/4.13) and rerun the application - this will verify the HW chain : USB port/cable/controller. Once it's done then you can switch again to 4.16 kernel and focus on the uvcvideo enablement.

Hi sorry for late response.. No unfortunately, it was not solved out but I am pretty sure the problem from the kernel since there are other software and drivers show similar error (E.g. Virtual Box). you may close the issue. I will try to revert the kernel (I can not right now). I will open new issue if I face further problem.
Thank you very much for your collaboration.
