OK, if nobody knows how to change it, is there at least a way to detect
from my kernel driver what numeric prefix the audio stack is adding to my
friendly name? The reason is that I am exposing a (third party standard)
ASIO audio device in addition to the native Windows MIDI device. Obviously
I have complete control over the ASIO device name, and ideally I'd like the
ASIO and MIDI device names to match.
Regards,
Andrew

My client wants to override the friendly MIDI device name specified in the

"My Device"
"My Device (2)"
"My Device (3)"

of "2- " onto the device name. Where does that come from, and is there a
way to override it?
I can already change the FriendlyName successfully
via IoOpenDeviceInterfaceRegistryKey following IoGetDeviceInterfaces with
the PDO. This sends me to the following registry location, at least on
Win8.1:
Key:
Control\DeviceClasses\{6994ad04-93ef-11d0-a3cc-00a0c9223196}\##?#USB#VID_<myvid>&PID_<mypid>#<myserial>#{6994ad04-93ef-11d0-a3cc-00a0c9223196}\#Uart\Device
Parameters
Value name "FriendlyName" of type: REG_SZ
When I change the FriendlyName value, I can successfully see the new name
as I enumerate MIDI devices, however I also still see the unwanted, and in
my opinion, no longer necessary prefix of "2- ", so I end up with a device
name of "2- My Device (2)" and so on. Ideas?

Andrew
