As an aside, I'm fairly sure from what I've read onNokia
documentation that theNokia6500Classiccan do both a host and non-
host mode.  That might not be important, but I've mentioned it just in
case.

Okay, well here are what the two programs reported.  Does this give
any indication to a solution?

AFAICS, the only pertinent info is that your phone's USB port, when
configured as a client, is externally powered and can draw up to
500mA, which is USB's limit. I was thinking that you could connect
your audio adapter to your PC as a client, if indeed that is how it is
designed, and then interrogate it in similar fashion. If the PC shows
that your audio device demands more than 100mA, then that would be a
problem according to Nokia's documentation.

For host configurations, Nokia's documentation states that ...

"The Nokia 6500 Classic and Nokia 8800 Arte mobile phones, which are
based on the Series 40 platform, support USB audio devices. These
mobile phones will be referred to throughout the document as the
Series 40 USB hosts."

"The Series 40 USB host can sustain current up to 100 mA. It is
recommended to draw as little current as possible to increase playback
or speaking times. Based on recommendations by Nokia, an amount of 100
mW should not be exceeded during operation at maximum volume."

Thanks for your continued help Franc - Nokia themselves, meanwhile,
are so far coming back with nothing but attempts to try and fob me
off.

So if I understand this right, I have my headphones I want to plug in,
and the mini-USB to 3.5mm audio adapters bought from eBay. Are you
suggesting I get a mini-USB to standard USB converter, plug the audio
adapter into that, the headphones into *that*, and then run the two
programs again - posting my findings?
