kernel-2.6.23: USB key protection problem



Hi, I have Found this issue on:
 o f7   + kernel-2.6.23 (last from development)
 o f8t3 + up to date (then kernel-2.6.23)

In this 2 Scenarios My USB KEY for software protection not work.

On f7 + standard kernel my key work ok (see strace 1), if I install last
kernel from updates (or I use f8t3) my key not work (see strace-2)

Someone can suggest me some work around ... or this is a issue of new
version of kernel?

Many thanks.
