low framerate with UVC camera on iMX53_QSB

Hi,

I want to test a USB camera, UVC compliant with iMX53QSB.

My Camera is: Trust Nium HD, that support 30 fps in 1280x720, this is my target

I connect my camera to USB and I launch guvcview and by this program I control some parameters.

Maximum frame rate that i obtained in this configuration is 7/8 fps... why this?

Why I didn't reach 30 fps?

I try to disable autoexpsure mode, but only a bit improvement... from 6 fps to 8 fps...

Did I forget something? Is there some module to load before launch guvcview?

In my test i boot QSB with camera connected and next I launch guvcview.

I'm a neewbie... can anyone help me?

Thanks,

Alessandro
