On my Linux host (8.10), I have attached a Canon USB MF3110 printer and VirtualBox recognizes it without a hitch, however, when I add a device filter for the guest OS (windows XP), then try to restart the guest it crashes and is unable to recognize the VM. Giving this error message
Assertion failed at '/home/vbox/vbox-2.1.2/src/VBox/Main/MachineImpl.cpp' (6034) in nsresult Machine::saveSettings(int).
Unexpected exception 'N3xml8XmlErrorE' (PCDATA invalid Char value 1.
Location: '/home/rp/.VirtualBox/Machines/winxp/winxp.xml', line 36 (1), column 135).
Please contact the product vendor!.
I searched through the bug reports but was unable to find anything relevant.
The issue is this unprintable character '^A' inside the USB device name, comes out as a little square box whenever I select the printer manually, but crashes whenever it tries to read in the virtualmachine file.
As soon as I manually edit the device filter out, it comes right back up happy as punch.
I would presume that it has something to do with not being properly escaped out?
<USBController enabled="true" enabledEhci="true">
<DeviceFilter name="Canon,Inc.^A MF3110" active="true" vendorId="04A9" productId="2660"...
Anyhoo, I'm creating this device filter via the VirtualBox GUI, and selecting the USB printer from the picklist.
Note, the printer works perfectly fine, I just can't use it inside a device filter.
If this is an unknown bug, please let me know so I can redirect it appropriately, or if any more details on how to reproduce it, the device string, yada-yada-yada.
Great software by the way.
