Hi Michael,

I this a "wanted" change or should I still see the same with 2.6.23?


Is this with CONFIG_SYSFS_DEPRECATED=y?

No, CONFIG_SYSFS_DEPRECATED is not set with both kernels. I had a closer look and noticed that I for some reason usbhid AND usbkbd were loaded.
I removed them both and loaded usbhid again. Now I had two entries for my keyboard.

P: Phys=usb-0000:00:1d.0-2/input1

U: Uniq=
H: Handlers=kbd event1
B: EV=3
B: KEY=1078 800c000 1e0000 0 0 0

Notice that Sysfs still shows /class/input...

With 2.6.23-rc7 ONLY usbhid got loaded and I got

So actually Phys is the same, just Sysfs got changed.


Hope that helps,
Michael
