No. First we need it to be complete / stable and add support for
EHCI
(btw, anyone feels like writing an EHCI driver?).
Is EHCi driver needed for keyboard support?
I was under the impression that keyboards always appear connected to
the low-full speed root hub, not the hihg-speed one.
This would change things. Can someone confirm?
Using system-profiler, it show me that the webcam is connected on a
High speed usb bus, and not the
keyboard :
USB Bus:
Host Controller Location: Built In USB
Host Controller Driver: AppleUSBUHCI
PCI Device ID: 0x27c8
PCI Revision ID: 0x0002
PCI Vendor ID: 0x8086
Bus Number: 0x1d
Apple Internal Keyboard / Trackpad:
Product ID: 0x021b
Vendor ID: 0x05ac (Apple Inc.)
Version: 0.18
Speed: Up to 12 Mb/sec
Manufacturer: Apple Computer
Location ID: 0x1d200000
Current Available (mA): 500
Current Required (mA): 40
this make sense, as a high speed bus is not really needed for a
keyboard, I guess.
