Any impact to other devices as this is a USB Hub device? Just for isolation purposes. uhub1 at uhub0 port 1 configuration 1 interface 0 "Standard Microsystems product 0x9514" rev 2.00/2.00 addr 2 I noticed that every time I rebooted this system my USB barcode scanner would beep for the second time when hitting this particular device as shown in the dmesg. The beep indicates that the barcode scanner is re-attached again in the USB port. During reboot beep happens twice. In my Raspberry Pi 4B this behavior doesn't occur as beep only happens once. Still the complete dmesg output here https://marc.info/?l=openbsd-arm&m=159642147427137&q=p3. Thanks and best regards, Archimedes
