Just realised that pywin32 ships with an example of this.
From my site-packages directory:
win32\Demos\service\serviceEvents.py
I haven't had the chance to try it out, but let is know if it does
meet your case.
Well I've given it a go and, naturally, it works ok. Except...
As documented(ish) (look under Remarks):
http://msdn.microsoft.com/en-us/library/aa363431%28VS.85%29.aspx
It'll only handle DBT_DEVTYP_DEVICEINTERFACE or DBT_DEVTYP_HANDLE
That wouldn't matter too much since the device interface event
returns the name of the volume, which one can use to good effect.
Except...
The pywin32gui_struct library which parses the stuff coming back
from the events assumes that the string is NUL-terminated. But
it's a UTF16 Unicode string so it's "nul-terminated" after the
first byte. I'll raise this as a bug on the pywin32 tracker, but
meanwhile I'll try to get an example which works around it by
parsing the header manually, as per the windows message example.
Or I could monkey-patch the win32gui_struct module. Might be
easier.
