You'll need to use the DeviceIoControl function, exposed in
win32file from the pywin32 package. I don't think I've got
an example to hand, but you can pretty much transliterate
any C++ code. You'll have to roll your own structures, tho'.
There's a (random) example here in case it helps:

If I get the chance I'll put an example together.

FindFirstFile, btw, is sort-of exposed via win32file.FindFilesIterator
which wraps it and its companions as a Python iterator.
