VBox 3.0.0 r49315 on LinuxMint R7
with previous versions of VBox all filter details would be included when adding a device.
now I note that some details are not added as they used to be.
adding USB filters kinda works... it is when trying to edit the filter that I get a problem.
the fields allow one to add say the manufacturer or serialno but the details are not saved!
it seems that the only field that works is the Filter Name.
