Sorry that this wasn't clear from the beginning. Both devices function
properly, via bluetooth I was using mobile -phone connection and dial-up; At
usb stick I hold docs and files, which was readed just fine.
The only problem - is that both devices blinking. Since I don't see blinking
when devices inactive under other OSes, I assume that in FreeBSD there is
some additional, not needed device polling forgotten to be disabled, or I
don't know. If device is blinking, then something queries it, spending CPU
cycles :)
I'll give you more feedback in evening, will run again same tests with
latest FreeBSD to see if it's still actual.
