actually I spent on this about an hour (and didn't succeed). Ordinary 
usb stick was detected and worked at high speed whereas system refused 
to work at high speed with N900 on the same port.

However, accidentally I found mention (seems it was in mailing lists of 
Gentoo community or smth.) that there were observed several issues with 
BIOS and USB subsystem specific to the model of my laptop (hp6710b). The 
only way to treat it is whether to try reset BIOS to default values or 
remove/insert battery on mb. I followed that pieces of advice and that 
helpled (moreover system started (at last) to recognize internal 
bluetooth device).

Anyway, many thanks for your help and time and sorry for the noise.

Best regards,
