Re: [PATCH 1/3] properly report a single frame rate of 60 FPS

Re: Frame rate

Thanks for the response David, but somehow I want to recover, I use the asynchronous, usb_submit_urb call and the call back never returns... any idea why that would happen, I have no visibility beyond my layer...! when would the host, think the device is dead? no of PINGS? what is the condition u

tead. Have you tried using usbmon (see Documentation/usb/usbmon.txt) to track the data flow? > its a 2.0 system > > ANy idea whats the limit on the frame rate? > n linux..i am using a ubuntu system on the host side Your question is meaningless. There are always 1000 frames per second
