Hi @yechun1,

I don't see this issue. If you re-connect NCS1, can it be recognized and show in lsusb?
You can try to connect NCS1 to another USB port, not near D435 device. I wonder if any interference there.

[yechun1]

Test 1 - if not run realsense-viewer in backend. when re-connect NCS1, it could be recognized and show in lsusb.

Test 2 - if run realsense-viewer in backend, when re-connect NCS1, it could not see from lsusb. but from dmesg, it show first detected then disconnected..

Hi @yechun1,

Did you run the prebuilt realsense-viewer tool? Or, build from the source?
If you build from the source, is "BUILD_WITH_TM2" build option enabled?

I suspect the NCS1 is reset by realsense-viewer since our TM2 device has the same VID/PID with NCS1.
That's the reason you saw NCS1 is disconnected. My suggestion is to build realsense-viewer tool without "BUILD_WITH_TM2".
Let me know how it goes.

[yechun1]

Just verified, NCS1 could work without BUILD_WITH_TM2.

The issue was reported from ros2debian, the debian package was prebuilt by ROS2 buildfarm based default CMakeList.txt. Don't know why the value of BUILD_WITH_TM2 is true by default? As there nowhere set it from CMakelist.txt. I have submitted a PR(#2970) to fix this issue.

Disable BUILD_WITH_TM2 seems to be a workaround solution, is there any better way to fix the same VID/PID issue?

Anyway, it can solve our currently problem as we do not use TM2, thanks.
