Hi,
After upgrading to 2.6.23-rc7 for testing purposes I noticed that the

contents of /proc/bus/input/devices changed a little bit.
I now have the following entries for my USB-keyboard
....

P: Phys=usb-0000:00:1d.0-2/input0

S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb1/1-2/1-2:1.0/input/input2

....
with kernel < 2.6.23 I saw
....

P: Phys=/input0

S: Sysfs=/class/input/input0

....
I this a "wanted" change or should I still see the same with 2.6.23?
Kind regards,

Michael

Hi Michael,
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.

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,

Ok, this is expected. Input devices were converted form class devices

into standard devices. Unless SYSFS_DEPRECTAED is set to Y sysfs

changes are expected.

Ah ok, so this is a known change. I thought about enabling it for

testing but did not do it because I did not do it with 2.6.22 either.

Thanks for the clarification Dmitry.
Kind regards,

Michael
