Windows 10: How to get usb vendor id for a usb pnp monitor from its audioendpoint instance?

I have a type-c device called Mi paipai, which is a usb generic monitor device. I am developping an audio sdk in which i can get IMMdevice handler of Mi paipai's audioendpoint, but now i need identify the device by its usb vid and pid. How can i get its usb vid+pid when i get its IMMDevice properties? device monitor info: ID: DISPLAY\XMD00EA\4&6292b8b&0&UID224795: Generic Monitor Mi TV: Monitor GUID:

Pnp device instance id

Hi,

I was reading about drivers and PNP, and i was wondering- does the instance-specific-ID is in case sensitive?

<device-ID>\<instance-specific-ID>

I have an id:

\VEN_10B7&DEV_9905&SUBSYS_110210B7&REV_02\4&19d8fe94&0&00F0

and it contains both lowercase and uppercase letters in the instance-specific-ID part. Does it matter?

Thanks, Dor

USB PnP not working

This is a Windows 7 desktop system upgraded to Windows 10

Everything worked ok in Windows 7 but upgrading to Windows 10 has stopped a USB Plantronics sound adapter from working - settings shows USB PnP Sound Device Driver Unavailable.

OK, I thought, this is a fairly old USB sound stick so no problem I'll buy a new one. A new usb sound device was purchased and I got exactly the same problem.

A call to Microsoft Support failed to really get to the route of the problem but installing Windows 7 drivers for the new sound device worked ok. They suggested that the sound device didn't support Windows 10...

This is a 64 bit AMD processor system. I thought I'd check both the Plantronics USB Device & the new one on a Windows 10 laptop (also 64 bit AMD) They both worked fine!

More calls to Microsoft support with some pretty sketchy results... still no USB PnP drivers working on this system. OK, I thought let me buy some more USB audio devices, perhaps it is a problem. This time going for ones where the suppliers assured me they
worked with Windows 10 and were supported by Windows 10 and the USB PnP driver.

I now have 5 USB sound devices! All work fine on the laptop and none work on this desktop system - all showing the same error:

Setting: USB PnP Sound Driver Unavailable

Device Manager: Driver not installed. Clicking the Update Driver button fails to find any drivers

I've spoken to several Microsoft tech support people (although I have to say most of them didn't really seem very knowledgeable) & they've run through all the normal things, troubleshooters etc. but found nothing wrong just saying the device doesn't support
Windows 10.

Clearly the devices do work under Windows 10 and are all supported by the generic USB PnP driver - they work on the laptop ok. All the hardware must work ok on the desktop system because if you install Windows 7/8 drivers everything works ok.

This would seem to be an issue with USB PnP drivers specific to this desktop system...

Any suggestions gratefully received!
