make install 하고 udev rule을 복사한 뒤, 키넥트를 뽑았다 꽂으라고 한다.
| Build (if you have run cd depends previously, cd .. back to the libfreenect2 root directory first.) mkdir build && cd build cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/freenect2 make make install You need to specify cmake -Dfreenect2_DIR=$HOME/freenect2/lib/cmake/freenect2 for CMake based third-party application to find libfreenect2. Set up udev rules for device access: sudo cp ../platform/linux/udev/90-kinect2.rules /etc/udev/rules.d/, then replug the Kinect. Run the test program: ./bin/Protonect Run OpenNI2 test (optional): sudo apt-get install openni2-utils && sudo make install-openni2 && NiViewer2. Environment variable LIBFREENECT2_PIPELINE can be set to cl, cuda, etc to specify the pipeline. |

expresscard to USB3.0 을 써서 생기는 문제인가.. 아니면 빌드라던가 다른 문제인가..

usbfs 크기가 적으니 늘리는게 도움이 된다는데 해도 해결은 안된다.
기본은 ubutu 22.04 에서 16MB 인 듯한데 1000MB로 늘려도 안된다.

혹시나 해서 찾아보는데..
expresscard의 경우 PCIe 2 or USB 3 mode 일 경우 3.2Gbps로 USB3.0의 5Gbps 에는 어떤 모드던 부족하다.
그런데 풀 대역폭을 쓰진 않을수도 있긴한데.. USB 장치에서 필요로 하는 대역폭을 다 커버 할 수 없는건가?
| Speed 480 Mbit/s effective (USB 2 mode) 1.6 Gbit/s effective (PCIe 1 mode) 3.2 Gbit/s effective (PCIe 2 or USB 3 mode) |
[링크 : https://en.wikipedia.org/wiki/ExpressCard]
칩셋인 uPD720202도 스펙상 PCIe Gen2 1 lane 이고, 속도까진 나와있지 않다
| System I/F: PCIe Gen2 x 1 Lane |
i5-2520m 도 PCIe Gen 2 라고 하는데
| 확장 옵션 PCI Express 개정판 2.0 PCI Express 구성 ‡ 1x16, 2x8, 1x8+2x4 최대 PCI Express 레인 수 16 |
pci-e 2.0 lane 1은 5.0GT/s 이고 5Gbps로 계산이 되긴한다.
반대로 생각하면 USB3.0이 생각외로 빠른거구나..

[링크 : https://en.wikipedia.org/wiki/PCI_Express]
| Depends on your thinkpad's generation of Expresscard Gen 1 is 1.6gbps Gen 2 is 3.2gbps Gen 3 is 6.4gbps, but each usb port can only do a max of 5gbps In this case it's a T420 so it has gen 2 expresscard |

expresscard 34 규격의 sony sxs pro 라는 저장장치 인데
우연인지 아니면 대역폭 한계인지 3.2Gbps가 검색되서 나온다. expresscard와 pci-e 와는 속도 차이가 존재하는건가?
| Max. Speeds Read speed 3.5Gbps (=440MB/s) (1) Write Speed 3.2Gbps (=400MB/s) (1) |
