Windows 7: Missing microphone boost with USB mic

Longish post. tldr version: how can I force my microphone's output volume to be higher when there is no boost option due to it being garbage USB?

I have a Logitech USB desktop microphone. It really struggles to pick up my voice at a reasonable volume. I basically have to shout for my voice to be heard at a reasonable volume over VOIP, or have the mic extremely close to my head. This isn't really feasible since I'm used to being able to lean back with a headset. I've heard this sort of fail is pretty typical for this mic, and is caused by a design flaw/factory flaw that leaves the internal preamp unpowered. I don't own a soldering iron to correct this, so...

I have the volume at 100%, but there isn't a 20db boost option (or the Windows 7 slider). I've always found this option is absolutely necessary for any mic I've used, although this Logitech is exceptionally poor in an unboosted state. Is there any way I can force the boost via registry, 3rd party software, etc.?

-I'm using Teamspeak3, and it doesn't have outbound volume boost, so no luck there.
-Logitech supplies no drivers (pnp), so there aren't any tweaks there.
-Since it's USB, my "soundcard" isn't really in the equation. Don't suggest I reinstall its drivers.




Any help/ideas are appreciated.
