select timeout error

[ajal-fh]

I'm currently running two lepton 3.5 cameras using two purethermal mini boards. I use opencv for continuous streaming of images. One of the boards runs continuously without any errors (tested for 2hrs). The other board gives 'select timeout' error after an hour (As i have tested multiple times the duration for which it runs without problems varies). As I could understand this timeout error occurs when there is no data send from the usb video device. I have also replaced the lepton camera on this purethermal mini and still the issue persists. Any help would be much appreciated.

tested on
Raspberry Pi 3b+ (Debian stretch, OpenCV 3)

Same here with Opencv 3 C++ and Python3.6.

Ubuntu 16.04 with Intel I7 NUC

Edit: Camera wasn't mounted firmly.

I'm also facing same issue on Ubuntu 20.04, intel i7.
The system detected the Lepton camera(Lepton 1.6) correctly, but cannot access the camera view.
I tried in python. Anybody find the solution?

Edit:
Hi, I solved it. Just stupid mistake, I didn't set the camera on PTmini well. Thanks @jarvis-owl

Hey guys,

I think this has something to do with the uvcvideo settings in the linux kernel. May you have a look here and maybe report your findings?
