I have a laptop like this one https://help.ubuntu.com/community/Aspire1830T. But with bluetooth, which was clearly visible and functioned until the laptop was win7.
Staged 10.04 - no bluetooth. Neither lsusb nor rfkill list, nor with
loaded with acer-wmi either with unloaded, on all available cores, even
on the linux-image-2.6.35-020635rc1-generic.
But after double-clicking FN-F3 (off and on all wireless devices), the adapter appears for a short time.
WORKAROUND: Renaming /lib/firmware/ath3k-2.fw to ath3k-1.fw just helped me to resolve bluetooth problem.
Here is part of dmesg:
