Turns out that USB2/2.0 devices may not work without the Virtualbox Extension pack hence the following sysctl needs to be run in order to convert USB2 devices to 1.1 sysctl hw._hs=1 It’s from the writer of the Virtualbox FreeBSD usb driver (and also the FreeBSD usb maintainer as well). My printer was definitely running USB2, usbconfig confirmed it: ugen4.3: at usbus4, cfg=255 md=HOST spd=HIGH (480Mbps) pwr=ON Then it occurred to me, could I force the printer to negotiate at usb1 or usb1.1 speeds? A lot of google searching revealed nothing, I looked at using usbconfig, usbdevs all proved pointless until I found this post. A quick google search revealed it’s got native binaries that don’t work under FreeBSD. A look at Virtual box’s website indicated there was one for all platforms. I clicked the tick box and got a dialog complaining that USB2.0 could not be enabled due to a missing extension pack. It wasn’t until I noticed that USB2.0 was deselected in Virtualbox that it all made sense. Hence I had to fix the issue.Īt one point I even noticed that the printer was being recognised by the FreeBSD ulpt driver and I thought that could be a problem so tried to disable that. However, no matter how much driver updating, plugging, replugging I did windows would show the printer existed but kept putting a yellow triangle next to it indicating it needed ‘Trouble Shooting’. The crazy thing was even Windows was able to see the device. Even Virtual Box was able to see the device. FreeBSD was able to see the device (usbconfig) showed it clearly. I’d followed the guide about enabling USB support under FreeBSD with virtual box at and other USB devices worked fine. Sadly I soon found that my USB printer did not work under the VirtualBox VM under FreeBSD. This worked under Linux so I think twice when I finally nuked the Linux partition. One requirement of this package is the need to print. I have a number of applications which sadly are Windows only applications, one is accounting package. The change over for almost everything was smooth except for one thing. Recently I got around to converting my last Linux box over to FreeBSD.
