http://int.main.jp/prog/lin_piece.html で

isdをrootで動かすんだったら別に大丈夫だけど、

と書いてあるけど、sudo ./isd -c ではダメだった。

usb_strerror() は strerror(errno) を返している。
"No such file or directory" = ENOENT

https://github.com/libusb/libusb-compat-0.1/blob/master/libusb/core.c#L108-L109
libusb では LIBUSB_ERROR_NOT_FOUND が返ってきていることがわかる。

usb_set_debug(1); したらもうちょっと情報出てきた。

libusb: warning [ep_to_pipeRef] no pipeRef found with endpoint address 0x02.
libusb: error [submit_bulk_transfer] endpoint not found on any open interface
No such file or directory

usb_set_debug()での情報がもうちょっと欲しいと思い、libusb 0.1系をビルド、リンクしてusb_set_debug(4);してみたが、デバイスを見つける段階で失敗してしまい、むしろ後退。

多分USB 3.0のバスから先を見に行けていないので、libusb 1.0系＋libusb-compatでないとダメ。

usb_set_debug(4); で libusb 1.0 のログ取れるよう libusb-compat をカスタマイズ
https://github.com/zurachu/libusb-compat-0.1/tree/for_debugging_application

autoreconf --install
./configure --enable-debug-log
make
