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:

- download libusb-1.0.0.8, unzip to external (result in a external/libusb-1.0.0.8)
- run ./configure -disable-timerfd
- 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) - add 3 Android.mk files
sync to target, run

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/usb2008 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...
