Now this is getting most interesting….
1) Just fyi,
For Vista, when you look at Device Manager Details tab and use that pull-down menu, you can rt click to copy/paste the values you see (not true if someone's running XP)
2) I’m quite curious about your firmware update comment
So this issue is defintely related to the firmware upgrade (because your Device ID has indeed changed!) and possibly the driver update as well. Will get back to you with more.. and aside from my 2 firmware related questions above, anything else you noticed or recalled occuring between firmware updates and your headset behavior?

Tell me more about this firmware...I already have the firmware upgrade...in fact have to install it every time the headset is connected, otherwise the in line volume control and mute button don't work
- Have you had to constantly re-install the firmware since day one with Vista?
- Did the headset ever work under Vista before you ran the firmware upgrade?
- Part of why i'm so interested in your firmware now is because of what i found in your regsitry!
On the one hand
- Device Manager shows a Device Instance Path that clearly indicates your headset driver's registry entry is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_074D&PID_3554&MI_00\7&84b63cc&7&0000\ - And the registry subkey FriendlyName currently= Micronas USB Headset is the entry that results in the device name you’re seeing
I also found a different device ID entry in your registry for a device with the FriendlyName = Sennheiser USB Headset! (see below. Scroll the code box down to the end)
Now, i previously indicated that the Device ID never changes. (And it normally never does!)
=> But in your case it would appear to have changed from: VID_1395&PID_0002&MI_00 to VID_074D&PID_3554&MI_00
=> VID stands for Vendor ID
=> VID assignments are controlled by an international organization
=> VID_1395 is assigned to Sennheiser Communications A/S
=> VID_074D is assigned to Micronas GmbH
Normally, Device IDs don't change EXCEPT now that i learned you've been applying firmware upgrades to your headset, i see how that's possible to have changed. Which also now plays into the big picture. As a firmware upgrade is the only way i'm aware of to change a device's Device ID (as its Device ID is programmed into it via the firmware in the first place!)
