DisplayLink

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	I'm trying to connect a DisplayLink device to NetBSD 8. This product
returns :

 port 3 addr 1: full speed, power 500 mA, config 1, USB Audio(0x8915),
vendor 10ae(0x10ae), rev 1.00(0x0100)
 port 1 addr 3: high speed, self powered, config 1, AB105 5inch(0x01c4),
DisplayLink(0x17e9), rev 1.07(0x0107), serial 110407-000010

and is enumerated as ugen by kernel. Thus, I have tried to add in udl.c
driver a new entry in udl_devs[] table:

{ USB_VENDOR_DISPLAYLINK, 0x01c4 }

but this device is enumetared again as:

ugen0 at uhub6 port 1
ugen0: DisplayLink (0x17e9) AB105 5inch (0x1c4), rev 2.00/1.07, addr 3
ugen1 at uhub6 port 2
ugen1: vendor 0afa (0xafa) product 03e8 (0x3e8), rev 2.00/2.00, addr 4

	As this device runs fine under Linux with standard displaylink driver,
I suppose it should run under NetBSD with udl driver (or minor
modifications). But why this device is not enumerated as udl device ?

	Best regards,

	JB
