Xtion and USB PCIe host card problems

[Matt Arnold]

I was going to connect multiple Xtion sensors into one PC.

The motherboard USB configuration was able to support two sensors. To
add support for additional sensors I installed PCIe USB cards. This
worked on my test workstation (using older, USB 2.0 adapters in PCI
slots) so I was surprised when the new setup failed to recognize the
sensors (code 10 fail when connected)

I have tried two different PCIe USB 3.0 cards from two different
manufacturers hoping that it was just a (USB card) driver fluke:

attempt 1: Syba SD-PEX-20047
http://www.sybausa.com/productInfo.php?iid=27

attempt 2: Azio AUDU3
http://www.aziocorp.com/product/peripheral/pci-pcie/audu3.htm


both with the same results. If I plug the depth camera into a USB port
on the PC, it works. If I plug any depth camera into a PCIe USB 3.0
card, it fails to initialize the device.

these are both USB 3.0 cards because that's what I could get my hands
on in short notice. They are supposedly USB 2.0 backwards compatible
and I confirmed that they work with other devices such as mouse,
keyboard.

has anyone had any similar experiences using PCIe USB host cards and
Xtion sensor compatibility?

the problem has nothing to do with your usb hardware.
connecting multiple xtions to one pc generally does not seem to work:

@Matt.. I have the same problem too... I cannot get the second Xtion to work on any PCI or PCIe based USB 3.0 controllers. Also, I have found that the same problem occurs when I connect the second Xtion to the USB 3.0 controller that comes with the motherboard. So, this makes me think that there is a compatibility issue with Xtion and USB 3.0 controllers (even though USB 3.0 specs are backward compatible with 2.0)...

 

Any thoughts on this anyone ?

I have the same problem with the Kinect and a USB3.0 ExpressCard on my
MacbookPro:

There's really something fishy happening between Kinect/Xtion and
USB3.0 controllers....

@dtr - Kinect works fine with usb 3.0 controllers for me... Just the Xtions dont !!! So maybe the usb chip in xtion is incompatible with the usb 3.0 specs !! maybe ???

Hi Prasanna,

 

Are u using the PCI express card or the PCI card ?

 

I'm thinking I want to buy the the 3.0 USB card, but still confused which PCI type should I buy for applying Kinect to my desktop.

 

I need it to apply more than two kinects to my desktop.
