Hi,
on FreeBSD systems, I had troubles using a USB joystick with SDL.
There are two problems in src/joystick/bsd/SDL_sysjoystick.c .
- The macro __FreeBSD_version is compared to inappropriate numbers.
According to
http://www.jp.freebsd.org/cgi/cvsweb.cgi/src/lib/libusbhid/usbhid.h
http://www.jp.freebsd.org/cgi/cvsweb.cgi/src/lib/libusbhid/Attic/libusb.h
http://www.jp.freebsd.org/cgi/cvsweb.cgi/src/lib/libusbhid/Attic/libusbhid.h
the APIs of USB HID are common in each following groups of OS versions,
a. 4.1-4.5
b. 4.6-4.8, and 5.0
c. 5.1
- open() error
$ uname -sr
FreeBSD 5.1-RELEASE
$ ls -l /dev/uhid0
crw-r–r-- 1 root operator 122, 0 8 3 14:06 /dev/uhid0
Then, open("/dev/uhid0", O_RDWR) fails.
It seems that this device file does not need to be writable, so O_RDONLY
may be suitable.
The attached patch is for src/joystick/bsd/SDL_sysjoystick.c revision 1.17 .
