USB filter IsActive flag is not editable => Fixed in SVN

[666f6f]

1. Create a Virtual Machine
2. Open the USB settings for that machine
3. Add a (dummy) USB filter and click OK. The filter should be Active, which is the default value.
4. Again, open the USB settings for that machine
5. Uncheck the checkbox to the left of the dummy USB filter and click OK. The filter should be Inactive now.
6. Again, open the the USB settings for that machine. Pay attention that the filter is still Active.
