Do not even try to install these drivers for BT dongle.. Install XP SPack 3 and reboot - WinXP will install default drivers that work just fine.. (USB-BUS-enumerator is not taken into accoun w/ thi driver pack so - if you change USB connector for this 'toshiba-chipset-dongle' >> you'll get unknown device... ending w/ that famous >> dev. is not working properli.. :p
