I currently manage my printers via a VirtualBox XP instance running on my OpenSolaris server. My 2 year old daughter was irresistibly drawn to the UPS and shut it off which left the USB devices in an unusable state, they would show up in the list of available devices but VirtualBox couldn’t reconnect them.

To fix this I did the following:
prtconf -v and look until you find the device you want to fix, in my case it looked like this
printer (driver not attached)

Go to the compatible area and grab the first usb string from the value section
usb3f0,2b17.100 in my case

rem_drv ugen
add_drv ugen -m ‘* 0666 root sys’ -i ‘”usb3f0,2b17.100″‘ ugen

This should repair the issue and allow you to reconnect the driver.

Until now the only solution I had was to plug it into my primary desktop and share it which wasn’t optimal, I originally tried to run Xen under Solaris with a Windows XP guest but the support for USB bridging isn’t there yet.  I switched to VirtualBox but the attempts to get it to mount the usb device were always failing with errors in /var/adm/messages

Typing in the command manually showed that ugen wasn’t able to be properly mounted,  poking around I found some articles about getting cameras to operate under Solaris and  followed them to remap the printer device as a ugen as far as Solaris was concerned (Since I can’t actually reliably print with the printer under Solaris anyways this was no loss).

After that I hotplugged the printer and was able to finally mount and share the printer under my windows XP VirtualBox instance.

Hopefully this will help others who want to get a similar situation resolved with VirtualBox and Solaris.
