Add D-Link -U5 device id 1e0e:ce16 into option driver. The device · 64bc3f5c

Zhang Le authored Nov 10, 2009

has 4 interfaces, of which 1 is handled by storage and the other 3 by
option driver.

The device appears first as CD-only 05c6:2100 device and must be switched
to 1e0e:ce16 mode either by using "eject CD" or usb_modeswitch.

The MessageContent for usb_modeswitch.conf is:
