windows asking for GUID_TRANSLATOR_INTERFACE_STANDARD from my USB HUB PDO

NTDEV
1

I’m revisiting my virtual (xen) USB driver and it isn’t working under
Windows 2008R2. While that’s not particularly surprising as a virtual
HUB appears not to be supported, I’m hoping it isn’t too hard to fix.
Windows appears to ask for something called
GUID_TRANSLATOR_INTERFACE_STANDARD from my device. It also asks for such
a thing under XP but doesn’t seem to be a problem there.

Is this something Windows should be able to do without, or is it like
the BUS_INTERFACE_STANDARD that Windows can fake under XP by falling
back to the HalXxx functions but not under AMD64?

Thanks

James

You should be able to get away with not supporting this interface

Thanks Doron. I think I’ve tracked down the problem… Windows is (quite sensibly) asking for V7 of the hub interface, then for V6 if it doesn’t get V7, but I only implemented V5.
