argyllcms and usb (0.1 and 1.0)

[Boris Samorodov]

Hello, All!

I try to build argyllcms (http://www.argyllcms.com/) at FreeBSD:
-----
% uname -a
FreeBSD bsam.wart.ru 10.0-CURRENT FreeBSD 10.0-CURRENT #8 r246714: Tue
Feb 12 22:26:27 SAMT 2013
bsam at bsam.wart.ru:/usr/obj/usr/src/sys/BB64X  amd64
-----

The program uses USB-0.1 and USB-1.0. There is a remark at sources
that since libusb1 does not support FreeBSD, usb-0.1 is used.

When compiling I get the following error:
-----
spectro/usbio.c:741:17: error: use of undeclared identifier 'dev'; did
you mean 'div'?
                        descriptor = dev->descriptor;   /* Copy */

Relevant (imho) parts from the source file:
-----
[...]
#ifdef USE_LIBUSB1
# include "libusb.h"
#else
# include "usb.h"
#endif
[...]
                        /* Get a copy of the device descriptor so we can
see device params */
#ifdef USE_LIBUSB1
                        if (libusb_get_device_descriptor(p->ppath->dev,
&descriptor) != LIBUSB_SUCCESS)
                                error("Get device descriptor on USB port
'%s' failed with %d (%s)",p->ppath->path,rv,libusb_strerror(rv));
#else
                        descriptor = dev->descriptor;   /* Copy */
#endif

GCC version of the error message:
-----
spectro/usbio.c: In function 'usb_open_port':
spectro/usbio.c:741: error: 'dev' undeclared (first use in this function)
spectro/usbio.c:741: error: (Each undeclared identifier is reported only
once
spectro/usbio.c:741: error: for each function it appears in.)
-----

Seems (from my very inexperienced in USB POV) that the program
wants libusb-0.1 but gets libusb-2.0... So I'm stuck here.

Questons.
1. Should I use some additional flags to build sources using libusb-0.1?
2. Is a note about FreeBSD about libusb1 is stale and lubusb1 is
supported? Sould I use some flags to use libusb1?

Any help is appreciated. Thanks!
