| Post subject: | Issue with 4 port usb3 card |
Hi folks: I replaced one of my 2-port usb3 pci-express cards with this 4-port model: http://www.amazon.com/Compatible-UtechS ... =usb3+card I had a terrible time getting it to recognize the ps3 eye cameras, and if I only hooked up 2 cameras to the port, it had terrible frame rates of 5-15fps. Does anyone know what I should try next, or if there is a good 4-port usb3 card which will work with DMC Standard? Thanks, Michael |

Are you upgrading the card just to increase the number of ports? If the old card worked, just add a hub. This will allow you to connect more devices to the controller. However, you should be aware that having more ports on a card does not mean the card has more bandwidth to handle more devices. If you're trying to accommodate more devices for computer, you need to add, well, more controller cards to your computer. Replacing an existing card does not give you additional controllers no matter how many ports it has. Here's some info from the wiki: Quote: Important! - You can plug only one MS Kinect / ASUS Xtion / PrimeSense Carmine sensor to one USB controller. 1 USB controller bandwidth is not enough to record from 2 sensors. - You can plug not more than 2 Sony PS Eye cameras to one USB controller, otherwise you will not be able to capture at 60 fps with 640 x 480 resolution. Now, if you were upgrading a USB 2 card to a USB 3 card, that would be different. A USB 3 card may allow you to connect more devices than a USB 2 card can handle, but it depends on the device and the data options you've chosen to save. But upgrading a USB 3 to a different USB 3 won't make enough difference for adding more devices. For example, here's my setup: I have two separate USB 3 controller controller cards, one for each Kinect--when recording mocap, I do not connect anything else to these two cards. My computer's motherboard has two on-board USB 2 controller--I use one controller for the the BT dongle to record from the three PS Move devices, and the remaining USB 2 controller handles my mouse, keyboard, scanner and various license key dongles. Hope this helps. G. |

I think the problem was that the chipset was VIA 805 instead of the 800 chipset ipisoft lists as problematic. However, it still had the same symptoms as the 800 chip, so I'm guessing the same issues are present in the new chip. I've got another post about using 8 cameras, and I'll post more there. Michael |
