Edirol (Roland) UM-1SX 0582:0009 "unknown"

[zsd1]

VirtualBox 4.2.16.

When I plug in the :0009 model of the UM-1SX (there is also a UM-1SX with id 0582:0052) and go to Devices / USB Devices to grant access to the VM, it is listed as "Unknown device 0582:0009 [0200]".

If I plug in the :0052 version, it is listed as "Edirol UM-1 [0200]".

On the host system (Slackware 64 14.0) lsusb reports these as

Bus 001 Device 018: ID 0582:0009 Roland Corp. Edirol UM-1SX MIDI Adapter

and

Bus 001 Device 016: ID 0582:0052 Roland Corp. EDIROL UM-1SX

This makes me wonder if an old/outdated list of USB IDs is compiled into VBox. Is that possible? If so, would it be a (*cough*) easy fix for an upcoming release?

Thanks.
