In Ipi recorder can't see four images from all cameras. Just three. 2 cameras connected to one Usb controller, other 2 cameras connected to another controller VIA Vectro VT6212L - 4-port USB 2.0 Host Controller. What I'm doing wrong

My PC.
CPU Intel core i5 2310 (4 core)
Ram - 8gb
Video - NVidia G-Forse 550 Ti
2 Hdd
Win 7 x64

Last camera, which not work, connected to VIA Vectro VT6212L - 4-port USB 2.0 Host Controller.

2 Usb Controllers was tested with flash card


What the problem?

I suppose the problem is with your additional USB controller. It has a known issue with PS Eye cameras mentioned in our wiki:
http://docs.ipisoft.com/Cameras_and_Accessories#Known_compatibility_issues
Why don't you use USB ports of your PC to connect all 4 cameras? It should have at least 2 built-in USB 2.0 controllers (on Intel chip), the problem is only to detect which ports are mapped to which controller.
Also switching to a lower frame rate may help.

Thnx. But I need stable 60 fps only.
I was tested 2 cameras on each controller
You right. VIA Usb controller gives low framerate with two cameras. Its about 15-24. But this controller is cheap.



Can I Buy another VIA Usb controller for connect two cameras to two VIA usb controllers and two cameras to one my pc usb controller. It will be work?







PS. Buy the ways. This is three cameras on my ps controller. No Good.

If a single camera connected to VIA controller shows good frame rate, then it should work.


Most probably all 3 ports are on the same USB controller. Try different combinations of ports.
Plug 2 cameras into any USB ports. Then plug third camera to other USB ports one-by-one until you find a working combination (if any).
