[Beaglebone] USB HUB dual camera problem

Hi,

I am developing an application on Beaglebone by using opencv libraries. Because beaglebone has only one usb host port, I connected a USB hub to my bone and connected two usb camera. Bandwith is not adequate for dual cam live stream capture, so I am trying to capture cameras by turn.

Firstly, I am capturing from camera 1 and then I am closing the capture. Secondly I am capturing from camera 2 and then closing the capture. This process is a loop but after a few turn my beaglebone gives error messages about usb hub and can not find /dev/video devices.

Why I can not sustain this scenario? Do you have any suggestion about solution?
I am using Angstrom distribution. Can any other distro like Ubuntu solve the problem? I think it is a hardware sourced problem but I am not sure.
Any suggestion would be great.

Regards

Ozkaya
