> [@TeKilla](#): > > press the reset button 22 seconds until the blue light was solid for 2 seconds I think that means you have an Aeotec Zstick 5 (I know of no other device that has a reset button and a colored light. There is a hardware problem with some versions of that device at least with Rpi4 regarding USB. I don’t know about almalinux 9 `(also this:controller (it is a vmware vm)-is this using ser2net?`, but with the behavior (logs seem to stop at a different time each try), it seems to me to be the most likely issue. As noted above, workaround is the intermediate USB 2.0 hub. You can google about the problem and other solutions.
