3418	RealSense camera freezes	goddard@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Windows-10-10.0.18362
ChimeraX Version: 1.1.dev202006070045 (2020-06-07 00:45:17 UTC)
Description
RealSense camera freezes, RGB image does not update, although depth updates.  Happens quickly at 1920,1080 or 960,540 but works at 640x480 all at 30 frames per second.  Works at 6 frames per second at 1920,1080 at least in a 3 minute test.

Get same freezes in RealSense Viewer application and there it gives USB Cam Overflow error message.  Reports online suggest this may be because the USB3 connection cannot deliver enough current to the device.  That is why it works at slower frame rates where presumably less current is needed.
