Don't use "hcitool cc ...", because this is only for development. What
does "hciconfig -a" show?

Run "hcidump -x" as root while connecting with hidd.

These are two different version numbers. What "modinfo hidp" shows means
that you use the HIDP version 1.0 with an additional patch for the
report protocol mode. I only put -mh1 after it to identify it, because
the HIDP with boot protocol mode is submitted for kernel inclusion.
