Support for Displaylink vendor devices

[modeenf]

Some links ​http://libdlo.freedesktop.org/wiki/ ​http://en.wikipedia.org/wiki/Displaylink ​http://lists.freebsd.org/pipermail/freebsd-usb/2011-July/010461.html ​http://docs.freebsd.org/mail/archive/2011/freebsd-usb/20110717.freebsd-usb.html

Vendor ID 0x17e9, Bulk endpoint

[korli]

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

[modeenf]

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

[siarzhuk]

Do you have listusb -v output for this device?

[modeenf]

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 :)

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

[siarzhuk]

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.

ok thanks

Getting this with listusb -v
