Thread: USB Microscope

  1. #1

    Default USB Microscope

    I just got a MicroView USB Digitial Microscope, but it doesn't work on Leap 15.1. It works on my Lenovo Android tablet, and on an old Windows XP laptop, so I know it's not defective. I could just use the tablet, but what fun is that? Running "Cheese", it says "no device found".

    I ran this:

    Code:
    lsusb
    Bus 009 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

    Bus 003 Device 013: ID 0ac8:3420 Z-Star Microelectronics Corp. Venus USB2.0 Camera
    Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 006 Device 002: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
    Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 002 Device 002: ID 9570:0301  
    Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    I assume the bold line is the microscope.

    Hi
    That's your problem, it's from Venus

    If you run the command usb-devices instead, can you post the relevant lines related to the device.

    Also if you open a terminal and switch to root user, unplug the device and run the command udevadm monitor and then plug the device in and post the relevant output.

    Hi
    That all looks good, do you have another app you can try eg mpv, vlc etc?

    Tried vlc

    Code:
    Your input can't be opened:
    VLC is unable to open the MRL 'v4l2:///dev/video0'. Check the log for details.
    Where is the log found?

    In Yast, "libquicktime0" was installed, and there was also "libquicktime" that wasn't, so I installed it. Now I don't get the complaint about it, but still no luck
