I have a nice Logitech USB headset that I use for Skype.

Does there exist an adapter that would allow this headset to be used
with a regular land-line phone? (It has a standard jack.)

I'd like to not have to have two separate headsets.

The problem is the phone line is analog and USB is digital.

Yep, I know... I designed the original USB port driver and receiver
chips... see my patent list.

Could be
done, of course, but I'm not aware of anyone who makes it.

Yet I find it odd that a headset (mike + earphones), so cheap,
actually digitizes the audio to run thru a USB port.

Sounds hokey to me. I suspect that USB ports may actually now be
configurable as "pass-throughs".

I note there are really cheap 2.5mm-to-USB adapters. Maybe the way to
go is to get an "analog" headset plus adapter ?:-)

I got a Plantronics one with a USB stick plus 3.5mm (not telephone
2.5mm) plug on it. Only thing is the microphone levels are very low so
that it's not really useful in the analog "mode", at least on my Dell
or MSI laptops.
