As the machines all have the same Ubuntu version installed, it should really be a question of installed packages or a configuration problem. Can you please try to install the networked printer via the CUPS interface and report back about what happens. Now there are two things I didn't notice earlier. In a previous mail you wrote: </pre> <blockquote type="cite"> <pre wrap="">The situation with usb is complicated. All other programs apart from cups can see devices on USB ports, including scanners and multifunction HDD unit, external usb disk drives.Virtual machine can also see all usb devices including printers scanners and hubs. </pre> </blockquote> <pre wrap="">Do you mean, Windows XP in the virtual machine can see the USB devices while the Linux host can also see them? For some reason I thought you were using virtualbox as virtualization software, but maybe that was wrong. If you would use virtualbox, the VM would only see the USB devices which are assigned to the VM by user selection and then the host can't see them while the VM is running. However you asked where you could remove a USB assignment, and therefore I think you might not be using Virtualbox but something else instead. Can you please tell us which virtualization software you use. And the second question is about the lsusb command we discussed previously: When you entered the command on the machine which can't see the printer, did you see a line which showed the printer ID? I think there should be the manufacturer name (Brother) and probably also the printer name mentioned.

Xsane finds the scanner whether the virtual box is open or closed. The virtual box sees both the printer and the scanner. I have removed and reinstalled the cups program but ubuntu still cannot configure the usb printer or the network printer, whereas the Virtual box can see and use both. I have 3 other laptops (another t400 and R61) and these both work correctly with the prinnters available in Ubuntu and the virtual machine. Regards Peter Goggin</blockquote> In desperation I reinstalled Ubuntu 16.04. Ubuntu now sees the printers etc. However I cannot get the Virtual Box to see the usb ports. When I first set this up VirtualBox was in the repository for Ubuntu 14.04. After it was all working I upgraded rather the installed 16.04. Presumably one of the many upgrades to 16.04 broke the system as far as seeing usb printers in ubuntu. Now I have to get my virtual box working. I tried the latest version for ubuntu 16.04 but while I can see my windows programs and run them I cannot see any usb ports. Can any one advise from where I should down load the software and extension packs ? Should I use Oracle's site? Since I cannot see Virtual Box in the installed software list I did not know how to remove it so I have done a clean install of Ubuntu 16.04. All of my own software in the home directory is regularly backed up so I have not lost any data. What repository etc do I need to add to keep the virtual box properly updated? It is many years since I have worked at terminal level in Linux and at 82 it can get a bit confusing. Regards Peter Goggin </body> </html>
