Hello, I bought a Dynamode bluetooth USB adapter in Ivory. It is Ultra Compact Dynamode bluetooth 2.0 adapter (it is the only one Ivory have). I inserted it into a Fedora 11 x86_64 machine.
lsusb recognizes it as: ... (Bus 002 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) ... Now, I tried several times to scan with this device (by "hcitool scan"). There was a Samsung galaxy android device about 2 meters from it (it's bluetooth setting were on) and some more bluetooth devices in the area (some in 10-15 meters radius, and some 2-3 meters right above, in the higher floor). The results were that sometimes scan found the Samsung galaxy device and usually one other device, and sometimes it did not find the samsung galaxy device, even that it is really near (2 meters from the Bluetooth UDB adapter, as said). The other device that it found was different each time. When I tried to perform bluetooth scanning ***with the Samsung galaxy device***, I **always** found **all** the devices, including those on the floor above. I assume that maybe this Dynamode bluetooth USB adapter is not so efficient and not of so high quality (event though it is said to find bluetooth devices in the radius of 100 m). So I would like to get ideas for why there is this inconsistency in scanning or alternatively a recommendation for a better bluetooth USB adapter for Linux.
