I do not know if the following has any significance
or not.

I got as far as seeing if my lumina build was working
on the NetBSD RPi4 configuration I've been testing
doing builds on.

This means that I plugged in a keyboard and mouse
(and I had earlier booted with the HDMI connected).
This was to a USB2 port, not USB3. The RPi mouse
was plugged into an RPi keyboard and the RPi
keyboard was in turn plugged into the RPi4.

A while after having quit lumina (so proving the
mouse was working while using lumina). . .

[ 1036.8743574] wsmouse0: detached
[ 1036.8743574] ums0: detached
[ 1036.8843604] uhidev2: detached
[ 1036.8843604] uhidev2: at uhub3 port 2 (addr 5) disconnected
[ 1038.8143543] uhidev2 at uhub3 port 2 configuration 1 interface 0
[ 1038.8143543] uhidev2: PixArt (0x093a) USB Optical Mouse (0x2510), rev 1.10/1.00, addr 5, iclass 3/1
[ 1038.8343570] ums0 at uhidev2: 3 buttons and Z dir
[ 1038.8343570] wsmouse0 at ums0 mux 0

So I tried plugging in to a RPI4 USB3 port instead
and started up and used lumina for a bit and then
quit lumina. After a while:

[ 2030.8193248] wsmouse0: detached
[ 2030.8193248] ums0: detached
[ 2030.8193248] uhidev2: detached

[ 2032.7793222] ums0 at uhidev2: 3 buttons and Z dir
[ 2032.7793222] wsmouse0 at ums0 mux 0

(Other than the timestamps, it is the same text for
both port types.)

With the keyboard/mouse combination left connected,
these messages repeated periodically:

[ 2030.8193248] wsmouse0: detached
. . .
[ 2093.0289255] wsmouse0: detached
. . .
[ 2154.9885123] wsmouse0: detached


The file system was on a USB3 SSD plugged into
one of the USB3 ports. That was it for USB
connections. The USB SSD continued to operate
well.

(There is a fan, EtherNet, and the serial console
as well. The power supply is rated for 5.1V 3.5A.)
