회사돈으로 산 물건인데.. 드라이버를 설치해야 하고(mac, win 드라이버만 제공)
리부팅 해야지 올라오는데
장치관리자를 보니 MS idd Device?
L이 아니라 i 였나 보네..
| The indirect display driver (IDD) model provides a simple user-mode driver model to support monitors that are not connected to traditional GPU display outputs. An example is a dongle connected to the PC via USB that has a regular (VGA, DVI, HDMI, DP, etc) monitor connected to it. |
indirectdisplaydriver0.dll 이라..
그래서 그런가 일반적인 VID PID로 들어가는 장치 식별자가 아닌 다른 형식으로 뜬다.
리눅스에서 연결해봐도 딱히 작동하는 느낌은 아닌데..

로그 상으로도 특별난 무언가가 출력되진 않네.. 뜯어 볼까?

아무생각없이(?) 윈도우 트레이에 먼가 있어서 죽였더니 화면이 안나온다(아까는 1 devices 이런거 안뜸)
내부적으로는 3개 까지 붙일수 있는 칩인가?

ultrasemi 라는 업체가 나와서 찾아보니 먼가 나오긴 한데
USB HDMI 캡쳐 장비랑 동일한 macro silicon 이라는 칩이 나온다. 숫자가 다른 동일 브랜드(?) 칩이려나?
