For a look back, I include my original post and Andrew Morton's reply.
Posting to this group didn't get any response.
I found a workaround, I unplug and replug the devices and it all works.

The consensus from Dmitry and Vojtech is that this could be either USB or
an input layer problem, but nothing changed in [UO]HCI or HID between the
two mentioned versions.
So this is more likely a recent regression in the USB code. Could someone
please grab it while it's fresh?

Hi.
I have this very same problem with CH CS568 and CH Pro Pedals.
I don't have really anything to add. As you said replugging the
device helps, but it's rather annoying.
Seems like every CH USB device suffers from this under later linux 2.6
kernels,

Right up until now - kernel 2.6.23-rc3 and on many hardware boxes since.
