You were correct. It was the other usb port. Seems port 9 still
isn't working, but the usb hub did reset both yesterday but is only
working with port 10 now.

I was previously using WSL to program the esp32s, but a windows
update borked the com ports so couldn't use that and went to using
VSC with PlatformIO on win for a while but right after win and vsc
updates about a month ago, something broke programming the esp32s
and I'm trying to determine what happened. I can program them one
time and then can **sometimes** connect to them but can no longer
program them after the first time.

When I try to reprogram them, vsc can't find the serial connection,
though the vsc terminal was just interacting with them. When I try
to connect to netbsd, I get this:

I would really like to get PlatformIO working under pkgsrc so I
don't have to depend on windows, which often breaks things... I
have part of it down but could really use help configuring a pkgsrc
pkg. I'm not a developer so am often clueless there.
