    What's the correct hardware ID of my graphic card ?


    Hello to everyone.

    I'm trying to disable my graphic card,NVIDIA RTX 2080 ti with devcon64 on Windows 10 emulated with bhyve on FreeBSD. As u can see below,I tried a lot of combinations,but it always says that cannot find the devices. So what ? What could be the working hardware ID ? thanks.

    You will need to enclose the whole HardwareID in quotation marks.

    Your application is responding to the & in the middle and it thinks you are issuing two separate commands. Using quotation marks makes your app see the whole HardwareID.

    I also think:-
    1 The command affects all devices with the same HardwareID [so would also affect any replacement of the same type of card] so I am surprised that your app works that way
    2 You could simply right-click & disable it in Device mgr instead.

    All the best,

    You seem to have stuck " within the HardwareID.
    - Put one " before the start of the HardwareID.
    - Put another " after the end of the HardwareID.

    Like this
    SomeCmdOrOther.exe "PCI\VEN_8086&DEV_5916&SUBSYS_07441028&REV_02"

    I'm glad the problem is resolved.

    You often need to add " to commands.
    If the 'argument' you are adding to a command has a space or a special character [such as an ampersand &] then the command can often only read the first part of it.
    There is generally no problem adding " to a Windows command's 'argument' unnecessarily.

    For example,
    Dir C:\Fred works, and
    Dir "C:\Fred" works, and
    Dir "C:\Fred and Mabel " works, and
    Dir "C:\Fred & Mabel " works,
    but
    Dir C:\Fred and Mabel does not, and
    Dir C:\Fred & Mabel is even worse - Windows thinks you are issuing two commands Dir C:\Fred and then Mabel and it has no idea what the command Mabel is at all.

    All the best,

    What's the correct hardware ID of my graphic card (EPISODE 2).


    Hello.

    I've reinstalled Windows 11 and I have passed again my graphic card inside the VM and I've got the same error as before,but this time I don't see any syntax error. Can you help me again to find what's the right ID of my graphic card ? (it should be the same of the previous time,but it does not seem). Please give a look at the picture attached...thanks

    The HardwareID of the device will not have changed.

    I notice that your command has changed
    from
    devcon64 disable "PCI\VEN_10DE&DEV_1E04&SUBSYS_250319DA&REV_A1"
    to
    devcon disable "PCI\VEN_10DE&DEV_1E04&SUBSYS_250319DA&REV_A1"

    I do not know if using a VM or Windows 11 make any difference to devcon.

    All the best,
