my program works fine on USB3.0 connect
when i try to use 2.0, cant get any image
capture data by bushound get correct data length 15372*170+10252 ==> 15360*170+10240(without uvc head) == 1280*1024*2
use e-CAMView show correct resultion and format(1280*1024 Y16)
i think it should be description problem? but dont know how to fix it
zip file is my SS and HS description function too large to post here
Solved! Go to Solution.

Hello,
From the descriptor file I understand that 1280*1024 *2 (bytes/pixel) @ 10 fps is to be streamed using USB 2.0. Is my understanding correct?
If yes, please confirm that the probe control structure used for USB 2.0 streaming has same settings as in USB 2.0 descriptors. Please share the probe control structure.
Also, share the UART debug prints to check if some failures are seen on the device side while streaming.

Glad to hear that video streaming worked after modifying the probe control structure
