How can I install Microdia UVC microscope?
3
I bought a Maozua 5mp USB microscope off Amazon (after checking in the reviews that it worked on Linux). Sadly when I connected it on Lubuntu 16.04 it does not work in guvcview or cheese.
I did some investigation. I show the relevant parts below:
ls /dev | grep video
video0
video1
The microscope is on video1 and a logitech webcam on video0. The webcam works when the microscope is not connected, but guvcview and cheese cannot retrieve video from it when the microscope is connected:

I disconnected the Logitech webcam, to avoid interactions, and ran cheese from the console (using sudo to avoid permission problems). I saw the following output:
paul@clio:~$ sudo cheese
[sudo] password for paul:

I googled 'microdia' and '0c45:6366' and found a lot of people have struggled with this microscope. Some believe they got it working, but the solutions are spread across long threads stream-of-consciouness-wise and I have not pieced together anything that works. I noted that most of the threads are dated 2008-2009. It makes me wonder whether a working driver became available after that period - but I can't find it !
Any help will be much appreciated.

I disconnected the Logitech webcam, to avoid interactions, and ran cheese from the console (using sudo to avoid permission problems). I saw the following output:
paul@clio:~$ sudo cheese

I googled 'microdia' and '0c45:6366' and found a lot of people have struggled with this microscope. Some believe they got it working, but the solutions are spread across long threads stream-of-consciouness-wise and I have not pieced together anything that works. I noted that most of the threads are dated 2008-2009. It makes me wonder whether a working driver became available after that period - but I can't find it !
Any help will be much appreciated.

What happens if you try to use VLC?

Sep 27 '18 at 1:01
I just tried the microscope on another machine running Lubuntu 16.04.2 and it works in both guvcview and cheese. The machine that fails has Lubuntu 16.04.4, although I doubt the slight version difference is significant. I have not tried VLC, but now that I know cheese can work, I think I must look for the difference in the configuration between these two machines.

Great find! Please update your answer so anyone else with the same hardware can benefit once you get it figured out. My advice is compare kernel versions and kernel modules that are loaded, i.e the output ofuname -raand the output oflsmod

Great. I just ssh'd into the second machine to start comparing. The working machine is Thetis. paul@thetis:~$ uname -ra Linux thetis 4.4.0-83-generic #106-Ubuntu SMP Mon Jun 26 17:54:43 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux paul@clio:~$ uname -ra Linux clio 4.13.0-41-generic #46~16.04.1-Ubuntu SMP Thu May 3 10:06:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Interesting, one is using Linux 4.4 and the other is using 4.13 - I assume the newer one is the one working correctly?

I bought a Maozua 5mp USB microscope off Amazon (after checking in the reviews that it worked on Linux). Sadly when I connected it on Lubuntu 16.04 it does not work in guvcview or cheese.
I did some investigation. I show the relevant parts below:
ls /dev | grep video
video0
video1
The microscope is on video1 and a logitech webcam on video0. The webcam works when the microscope is not connected, but guvcview and cheese cannot retrieve video from it when the microscope is connected:

I disconnected the Logitech webcam, to avoid interactions, and ran cheese from the console (using sudo to avoid permission problems). I saw the following output:
paul@clio:~$ sudo cheese

I googled 'microdia' and '0c45:6366' and found a lot of people have struggled with this microscope. Some believe they got it working, but the solutions are spread across long threads stream-of-consciouness-wise and I have not pieced together anything that works. I noted that most of the threads are dated 2008-2009. It makes me wonder whether a working driver became available after that period - but I can't find it !
Any help will be much appreciated.

I bought a Maozua 5mp USB microscope off Amazon (after checking in the reviews that it worked on Linux). Sadly when I connected it on Lubuntu 16.04 it does not work in guvcview or cheese.
I did some investigation. I show the relevant parts below:
ls /dev | grep video
video0
video1
The microscope is on video1 and a logitech webcam on video0. The webcam works when the microscope is not connected, but guvcview and cheese cannot retrieve video from it when the microscope is connected:

I disconnected the Logitech webcam, to avoid interactions, and ran cheese from the console (using sudo to avoid permission problems). I saw the following output:
paul@clio:~$ sudo cheese
[sudo] password for paul:
(cheese:3520): IBUS-WARNING **: The owner of /home/paul/.config/ibus/bus is not root!
libv4l2: error turning on stream: Protocol error

I googled 'microdia' and '0c45:6366' and found a lot of people have struggled with this microscope. Some believe they got it working, but the solutions are spread across long threads stream-of-consciouness-wise and I have not pieced together anything that works. I noted that most of the threads are dated 2008-2009. It makes me wonder whether a working driver became available after that period - but I can't find it !
Any help will be much appreciated.

What happens if you try to use VLC?
– Kristopher Ives
Sep 27 '18 at 1:01
I just tried the microscope on another machine running Lubuntu 16.04.2 and it works in both guvcview and cheese. The machine that fails has Lubuntu 16.04.4, although I doubt the slight version difference is significant. I have not tried VLC, but now that I know cheese can work, I think I must look for the difference in the configuration between these two machines.

Great find! Please update your answer so anyone else with the same hardware can benefit once you get it figured out. My advice is compare kernel versions and kernel modules that are loaded, i.e the output ofuname -raand the output oflsmod

I finally solved it. After a lot of time testing and theorising I came to the conclusion that the problem was nothing to do with drivers or OS versions. It seemed to be only one specific machine that had problems. This pointed to a hardware problem. By accident I chanced on an article about all the problems ASMedia USB3 devices have with Kinect2. The specs for my motherboard(Asus X99 Deluxe II) show it uses ASMedia for USB3, but not apparently for USB2. I switched my webcam and Microscope to the USB2 ports and have not had a problem since.
Many thanks to Kristopher Ives who put a lot of effort into helping me with this.
Conclusion if you are having trouble with UVC devices and have ASMedia USB3, try USB2 ports. Also ASMedia USB sucks !

Sounds stupid as the Webcam enumerates and appears to almost work, but I guess there's a low quality cable or circuitry inside the webcam (or it draws a lot of power) and USB starts to struggle as soon as it tries to transfer a lot of data.

I just tried the microscope on another machine running Lubuntu 16.04.2 and it works in both guvcview and cheese. The machine that fails has Lubuntu 16.04.4, although I doubt the slight version difference is significant. I have not tried VLC, but now that I know cheese can work, I think I must look for the difference in the configuration between these two machines.
