As far as I know, uvc can work well at 3*1024B/uF(24MB/s) in beagle xm, and it uses ISO transfer. I don't know if gspca uses ISO endpoint to transfer stream data. If it uses bulk to transfer video data, it will share the usb bandwidth with other devices. thanks, -- Ming Lei -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
