USB with libusb

[Eliot Blennerhassett]

Greetings,

I have been reading about general USB support. E.g.

http://www.winehq.org/?issue=331#USB%20Support%20in%20Wine

which mentions 4 scenarios for giving apps access to USB.

But here's a 5th that I am wondering about:

The Windows app has been linked to (win32) libusb.
How do I get it to use the linux version of libusb?
Will it "just work", or do I need to make a libusb.dll for Wine that passes 
calls through to linux libusb?

(I am talking to a hardware manufacturer that currently uses their own 
custom .sys driver to access usb on windows, suggesting libusb might make 
their app easier to port or just run with Wine)

thanks and regards
