Milestone: R1Unscheduled
Summary: Support for Displaylink (usb_graphic)Support for Displaylink vendor devices
Version: R1/alpha4.1R1/Development

I removed the relation with UVC and isochronous streams as these devices use a vendor specific bulk-only interface.

It does? Haven't looked at it. :)

Mine says USB\VID_17E9&PID_0360&REV_0112 USB\Class_FF&SubClass_00&Prot_00

Do you have listusb -v output for this device?

comment:4 by modeenf, 11 years ago

I haven't tested it on Haiku but I will paste a list :)

Some more links :), right now I just collect what information I can get my hands on :)

http://www.openbsd.org/cgi-bin/cvsweb/~checkout~/src/sys/dev/usb/udl.h?rev=1.21;content-type=text%2Fplain;only_with_tag=HEAD http://www.openbsd.org/cgi-bin/cvsweb/~checkout~/src/sys/dev/usb/udl.c?rev=1.76;content-type=text%2Fplain;only_with_tag=HEAD http://floe.butterbrot.org/displaylink/doku.php

What would be the best approach? Borrow udl.h from openbsd but make our own usb_grafic.cpp based on usb_audio?

As this is vendor-specific device the name usb_udl is preferred. In my opinion, the name usb_graphics should be reserved for devices of standard USB Monitor Class. Looks like the device works using bulk transfers so usb_audio cannot help a lot implementing the usb_udl driver.
