Hello,
As the title suggest I am trying to use a camera plugged into
a USB3 socket. it works fine plugged into a USB2 socket but luvcview
gives the following error:
---

The motherboard is running an Intel P55 chipset with the USB 3.0
provided via a NECD720200F1 chip. The cameras all work fine when
plugged into the USB2.0 socket provided by the Intel chipset. Below
is the ouput from the camera.
Output from LSUSB with a Logitech :
Bus 017 Device 002: ID 046d:0825 Logitech, Inc.
The same thing happens with a Philips SPC620NC camera, LSUSB is :
Bus 017 Device 002: ID 0471:0333 Philips (or NXP) SPC 620NC PC Camera
Is this something to do with the camera trying to push too much data
down the higher bandwidth USB3?
Any help or hints much appreciated.
Cheers,
Neil
