FreeBSD: libusb with functions for asynchronous URB's receiption ???

[FreeBSD Prospect]

Hi!

I am not a programmer, and I am only posting to this mail list, because I need 
support for my smartcard-reader (ReinerSCT cyberjack pinpad USB 0x300) in 
FreeBSD.

The manufacturer of that device already offers an open souce driver for Linux, 
and they are willing to port it to FreeBSD, but they gave feedback, that it 
is not possible ATM, because the needed functions for asynchronous USB 
Request Blocks (URB's) only exist for the Linux impmentation of libusb by 
now.

I do not know, what that means. That's why I sent a request to the 
libusb-devel mailing-list, and got this reply:

The current state of affairs is that there is no swiss-army-knife
library available that successfully abstracts all popular operating
systems' different USB programming interfaces.

libusb is indeed aimed at accomplishing this very task but there's
not a lot of FreeBSD experience in the project, even if some
interesting FreeBSD documentation passed through the list a while
ago.

I believe development efforts currently go towards finishing libusb
1.0 and the new/revised API it will have, but I guess improved
portability is also a high priority.

It is not quite clear to me, if this is now a matter to be handled by the 
libusb development team, of if it needs involvement of the FreeBSD dev-team 
as well.

Maybe someone with more insight can provide more information.
