Noted in your advice. I plan to have a powered USB 2.0 Hub in the chain but when I took a try with Ubuntu Linux image for Raspberry Pi 3 all the 4 USB ports functions as to no need for an external chain of USB 2.0 Hub device. That's why I began to ask and become curious if I have configured my OpenBSD system correctly or I missed something? I can print by attaching my printer to one of the USB ports, the second to my USB keyboard, the third port to my USB mouse and the fourth port to my barcode scanner. All works without any problem. I'm using the Raspberry Pi 3B power adapter with 5V with 2.5 Ampere capacity https://shopee.ph/product/18252381/190149839. > > > [dmesg snip] > > ... > > usb0 at dwctwo0: USB revision 2.0 > > uhub0 at usb0 configuration 1 interface 0 "Broadcom DWC2 root hub" rev > > 2.00/1.00 addr 1 > > > > Thanks and best regards, > > Archimedes > > > > > > On Mon, Aug 3, 2020 at 10:23 AM Archimedes Gaviola < > > archimedes.gavi...@gmail.com> wrote: > > > > > Hi, > > > > > > Good day! > > > > > > I installed OpenBSD 6.7 release and current (dated August 1, 2020) to > my > > > Raspberry Pi 3B.
