#12264 fixed unregister_netdevice => Fixed in SVN artie
Description

The problem I faced seems to be the same as this: https://www.virtualbox.org/ticket/10624

Ubuntu 13.10 with 3.11.0-12 generic kernel, virtualbox 4.3. Using virtualbox 4.2.18 on the same machine is perfect.

So the problem is when shutting down unregister_netdevice waiting for vboxnet0 to become free arrives as message.

#3383 fixed unprintable characters in usb device strings crash VirtualBox (unable to read in Machines .xml files) RP
Description

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!.


Result Code:

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.

Here is the relevant text from my machines.xml file.

<USBController enabled="true" enabledEhci="true">
<DeviceFilter name="Canon,Inc.^A MF3110" active="true" vendorId="04A9" productId="2660"...

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 by selecting it from the GUI.

If I go in and manually create a filter with enough of the matching details (serial number, device id, etc...) the filter works as expected.

#5089 fixed unplugging logitech quickcam pro crashes vbox guest => Fixed in SVN/3.0.8 Tor houghton
Description

After reading that USB high speed devices were somewhat supported, I thought it would be an idea to try my Logitech webcam again.

Bus 002 Device 021: ID 046d:0991 Logitech, Inc. QuickCam Pro for Notebooks

No picture appeared, so I decided to unplug the camera, which resulted in the whole session being aborted.

The host's log did not show anything:
