    Hi All,

    I am struggling to connect a Mini-VCI J2534 cable ($25 ebay cable) to Techstream. I'm using Mac OS 10.15.7 and running Techstream in VirtualBox.

    I selected the cable from Setup>VIM Select and selected XHorse MVCI.

    When I click the "Detail" button, I notice that the cable does not show as being connected.

    • I tried pasting the MVCI32.dll file from C:\Program Files\X Horse etc. etc. directly into C:\
    • I tried pasting it into Program Files
    • I tried renaming Program Files to Program Files (x86) and pasting the X horse files into the renamed folder.
    Any other ideas that I might try?

    Any cables that might work without issue that don't cost an arm and a leg?

    Thanks all!

    Have you enabled the USB port in the VirtualBox VM?

    Hello! As far as I can tell, I have enabled the USB port in VirtualBox -- I can see the XHorse cable listed in one of the options when I go to VirtualBox>TechStream>Settings>Ports>USB

    However, I do notice that when I am on the Ports>USB page that the options are kind of greyed out. "Enable USB Controller" is selected and "USB 1.1" is selected but USB 2.0 and USB 3.0 are also options but it's all greyed out. I added the XHorse cable manually by clicking on the plus/usb icon but that did not seem to affect anything.

    Any other ideas? Thanks for your reply!

    Usually you have to find a drop down menu labeled "connected devices" or something. Then find the x-horse cable and "disconnect from host".

    Then the VM operating system can use that device.

    Thanks for your replies! Not sure what happened but somehow from yesterday to today it is suddenly working. I do not know what triggered the change.
    • I went into the settings in VirtualBox and experimented with adding/removing the cable in the USB settings as well as manually adding it.
    • I also copied/pasted that driver file that I mentioned before into various places.
    • When I started today, I unplugged the cable, plugged it back in, and went to Device Manager in Windows XP inside VirtualBox and then when I plugged it in, Windows immediately recognized the cable and gave a little notification that new hardware was ready to use.
    • When I went back to TechStream, it recognized the cable as well and the error was gone.
    Thanks both for your help on this!

    I am pretty sure your USB ports are not being passed to the VM. You need to use the VirtualBox control panel for the Windows VM and check that the USB is set up to pass the M-VCI device to the VM. You need to have the M-VCI cable plugged into a USB port when you do this (it doesn't need to be connected to the car, though), otherwise you won't see the Connection. You will also likely need the VM shutdown but selected when you set this. You do not need to set up the M-VCI in the macOS Control Panel (I think it prompts you to set up a network connection, but just cancel that).

    I do not use VirtualBox, so I can't give you exact instructions on how to configure the control panel.

    I use VMWare and have confirmed if I uncheck the Future Devices M-VCI check-box in the Device Info in the Details screen, it shows "N/A" and "not connected" in Techstream. If it is of help, I get to that from the VMWare toolbar by selecting Virtual Machine -> USB & Bluetooth -> USB & Bluetooth Settings ... which brings up this screen:

    upload_2024-11-22_16-54-12.png

    If that checkbox is not selected, then the VM does not see the M-VCI cable.

    Again, the M-VCI needs to be plugged into the USB. If it isn't, you don't see that option.

    YMMV, but maybe that is enough info to navigate the setup. Otherwise, Google VirtualBox setup help.

    I would be inclined to download a fresh copy of the VM file and start afresh.

    It's certainly easier to buy an old tablet with xp or 7 on it :):):)
