Can you be more precise? What do you mean with "USB driver support"?

USB is a bus, a way to communicate datas. Since it was not part of the
original PC architecture, it was not part of the design of the original
Minix operating system, and still is not, including whole concepts like
plug-and-play.
When this work to fit this bus within the architecture will be
completed, the system will be able to dialogue with USB-connected
devices, and then can start the work to write USB drivers; or to reuse
existing ones, since the idea is to use DDEkit from L4 at TUDresden.

You can try to build a framework to support USB into the MINIX
architecture. Assuming this work takes some weeks, then you would be
able to compare the results you got, to the now on-going work done on
DDEkit port which is assumed to complete meanwhile.

hi Antoine,


DDEkit ??
... is it a wapper around the device drivers??
...and does it emulate any kernel's interface??


thanks in advance :)

... can be searched through the www. The first link I got was

http://wiki.tudos.org/DDE/DDEKit

and the second was

(I believe I mentioned T.U.Dresden in my mail, didn't I?)

Hej, indeed, the USB work is complete. UHCI/EHCI and OHCI
host-controller drivers plus USB HID and mass storage device drivers
will be available through pcksrc shortly.

Ciao, Dirk
