Why are you using an old version of KStars? Try with KStars 2.9.5 and see if get the same issue again.

The problem began in an installation of the KStars-Bleeding. The installation of v2.8.8 is a consequence of uninstalling and installing this version to see if the issues continued or disappeared. After some more testing yesterday, it may seem that the problem may not be directly related to EKOS, but a combination of the V4L2 driver and issues with my laptop's USB port (s). I replaced my USB hub and created a new profile in EKOS and the problem has so far not returned.
