Hi,

lsusb:

Bus 001 Device 004: ID 046d:c707 Logitech, Inc.
Bus 001 Device 003: ID 046d:c704 Logitech, Inc.
Bus 001 Device 002: ID 0451:2036 Texas Instruments, Inc. TUSB2036 Hub
Bus 001 Device 001: ID 0000:0000

Just be sure you have sshd up and running before switching the hub when 
using the diNovo Keyboard. ;)
This is also the reason for putting one of those stupid disclaimers into 
the source.

 Small utility for switching the Logitech Bluetooth-Hub from USB-HID-mode
 into bluetooth-operation.
