Grab Timeout on Jetson with Basler daA2500-60mci (USB3) — Fails in PyPylon and Pylon Viewer but the system detects the camera but not on port #865
Description
Describe what you want to implement and what the issue & the steps to reproduce it are:
Environment:
- Camera: Basler daA2500-60mci (USB3)
- Interface: USB 3.0
- Platform: NVIDIA Jetson (L4T / Ubuntu-based)
- PyPylon: latest installed via pip
- Pylon Viewer: Camera detected but does not stream.
python: 3.10.12 (main, Jan 8 2026, 06:52:19) [GCC 11.4.0]
platform: linux/aarch64/5.15.148-tegra
pypylon: 4.2.0 / 10.2.1.471
PROBLEM:
When accessing the camera using PyPylon, frame acquisition fails with a timeout:
TimeoutException: Grab timed out.
Possible reasons are:
- image transport not working
- camera uses explicit triggering and has not been triggered
- acquisition not started
- Tested multiple pixel formats but still did not work
- /dev/video0 present
- lsusb -t does not list the camera explicitly.
Timeout occurs even with:
- single frame grab
- trigger disabled
- low resolution tests
Any guidance or debugging steps would be greatly appreciated.
