Right I understand. I was hoping we could use libusb as it currently
work on both Windows and Linux but I see what you mean about the
implementation issues...maybe it will still be of help to someone.

Right now its a hardcoded hack to SetupDiGetClassDevsA that looks for
the iPods Vendor ID by talking to the /proc filesystem. If it finds the
device it does some other magic to access it. In the future we were
going to add some enumeration for other mass storage devices. I was
hoping we could make it generic enough that ReactOS and Wine could both
use the same code for device identification at least on the userspace
side because if I understand it correctly all USB devices under any OS
use the same ID system. I dont know how the other hardware such as PCI
and friends work.

Anyway there is not much to what we(codeweavers) already have and I
agree I dont think working together on this is going to be much help.

Thanks
Steven
