"Brothers" property in device manager

[FloSaunier]

Hi everyone,

I need to obtain the "brother" property of an USB device, using LabVIEW. I can have it in the "Details" tab of the property windows from the device manager.

I thought I'll find it in the registry key, but I can't find this particular property.

I used the management object in .NET too, but I can't find this property neither.

Any help is welcomed !

I would guess that this is a bad translation for the french version of your driver. None of my USB drivers has any property that even remotely would resemble "brother" or "brothers" (but I'm also not using any printer with that brand ).

I do have "Parent", "Children" and "Siblings", and the last is most likely what you are looking for.

Yes, it's litteraly the traduction of the french word "Frères".

So it's must be Siblings, I'll see if I can change the original post.

Thanks !

I think this is covered in this two USB Nugget found here and here.

Unfortunately, it's not... I saw them a lot of time and it's not working for me.

My device is a FTDI with a serial converter, so it's not VISA or RAW.

Well if it is a FTDI device with a Virtual COMM USB device, then VISA ASRL will definitely work. If not you will need to use an FTDI DLL to access the device. VISA RAW is not a good option I agree, as you would have to implement the low level protocol that way.

Yes, I have the FTDI dll working just fine.

My only issue is on the device selection (if I have more than one device connected). In order to link the device name with the dll, I need the siblings information.
