libusb-1.0.0.8 for android

就 這篇 http://android.serverbox.ch/?p=151 和 http://my0613.blogspot.com/2010/11/porting-lsusb-libusb-on-android.html 分別是 libusb 和 lsusb。

porting lib 還是和以前一樣，要先run ./configure. 產生 config.h，然後再自己改成 for android 的配置。

然後加入 Android.mk (兩個)

再修改一下 build error 的 file

我的 config.h: /* config.h. Generated from config.h.in by configure. */ /* config.h.in.

1. download libusb-1.0.0.8, unzip to external (result in a external/libusb-1.0.0.8)
2. run ./configure -disable-timerfd
3. modify libusb/io.c
   加上#define TIMESPEC_TO_TIMEVAL(tv, ts) \ do { \ (tv)->tv_sec = (ts)->tv_sec; \ (tv)->tv_usec = (ts)->tv_nsec / 1000; \ } while (0)
4. add 3 Android.mk files

OK to build, mm
sync to target, run bash-3.2# lsusb 1d6b:0002 (bus 1, device 1) 1d6b:0002 (bus 2, device 1) 0424:2517 (bus 2, device 2) 0a12:0001 (bus 2, device 3) 13fe:1d00 (bus 2, device 4)
不用 mount usbfs /proc/bus/usbfs 就可以動作(?)

查 libusb/os/linux_usbfs.c : static const char *find_usbfs_path(void) { const char *path = "/dev/bus/usb"; const char *ret = NULL; if (check_usb_vfs(path)) { ret = path; } else { path = "/proc/bus/usb"; if (check_usb_vfs(path)) ret = path; } usbi_dbg("found usbfs at %s", ret); return ret; } 用的是 /dev/bus/usb

2008 這篇 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=483392 有說不要再 mount /proc/bus/usbfs，請直接用 /dev/bus/usb..

但是到現在好像還很多人在用...
