@MartyG-RealSense
This is the 5th time rs-435i camera got damaged/stopped working after connecting to usb-c port on nuc-11 compute.

The only way to safely use the camera is to plug it through usb hub that connects to nuc-11.

we measured the voltage on the usb-c port of nuc-11 it spikes to 8v and that seemed to damaged our cameras.

It has been costly. Is there any particular limitation that I am not aware of or restriction on usb-c port usage.

rs-435i camera was working until yesterday, when someone unplugged the usbc port form the usb-hub and plugged it to nuc--11 directly, that damage the camera.

No device detected. Is it plugged in?

Hi @wendwosenbb Thanks very much for the information. Under normal conditions RealSense cameras should not be damaged at all by unplugging them from one port and inserting them into another.

I note that you have measured an 8v spike on the USB port of your NUC-11. I am not aware of past reports of damage to RealSense cameras in this way, though my research of USB power spikes in general indicates that it can damage the USB port on electronic devices.

Have you tested the camera with a different USB cable to establish whether possible damage is In the cable rather than the camera's micro USB port? Have you also tried having the USB cable inserted into the camera in both directions (USB-C cables are two-way insertion at the micro sized end).

Hi @wendwosenbb Do you require further assistance with this case, please? Thanks!

[wendwosenbb]

No. thank you for you quick response.

[MartyG-RealSense]

You are very welcome. As you do not require further assistance, I will close this case. Thanks again!
