Date: Mon, 01 Sep 2003 15:37:52 +0900 From: SUGIMOTO Sadahiro Subject: [SDL] [PATCH] bsd joystick Hi, on FreeBSD systems, I had troubles using a USB joystick with SDL. There are two problems in src/joystick/bsd/SDL_sysjoystick.c . 1. 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 2. 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.
