    Having had the same thing happen three times in a month on two different computers, I suspect that there must be something more profound going on...


    About a month ago my Bluetooth devices on my main desktop PC suddenly stopped working. On investigation, I noticed that in fact my Bluetooth card had completely disappeared from my device list; I couldn't do a driver update because there was no device present. Downloading the driver from Intel's website and installing it manually made no difference. The Windows troubleshooter was adamant that no Bluetooth hardware was installed on the machine. In the end I just bought a brand new Intel AC7260 card and installed it, and the problem went away.


    Earlier this week I had a related problem on my Surface Pro 3. Suddenly the built-in keyboard stopped working. Thinking it was probably a hardware fault, I tried to install my Bluetooth keyboard and mouse on it, only to find that now my Surface Pro also thought that there was no Bluetooth hardware installed. However, when I plugged the Surface Pro into its dock, the problem immediately righted itself and both keyboard and Bluetooth functionality returned.


    This evening I was working on my desktop PC again when a system tray message popped up to say that a USB device had stopped working. Immediately afterwards, I noticed that I'd lost Bluetooth yet again, and on running the same investigations as last time it seems that, once again, Troubleshooter is adamant that I have no Bluetooth hardware installed.


    If I hadn't had the problem on my Surface Pro as well I'd just think that something in my desktop's hardware was causing repeated AC7260 failures, but I now think it's more likely that this is a software problem. However, how would I go about troubleshooting it? Why would a Bluetooth failure be reported by the system as a USB device problem (when my USB device is an integrated board, not a dongle)? And what's the desktop PC equivalent of plugging a Surface Pro into its dock, in case that were to be the solution to this problem as well?

    Can't get Bluetooth working...

    If your sure that its recognised properly then have a look on this links page http://www.holtmann.org/linux/bluetooth/

    The only thing i can think of to fix if it isnt recognised by linux is the following:

    Firstly you have to find out what chipset your bluetooth dongle uses.
    Secondly i think your going to have to basically compile your own kernel and include the module for the chipset that your bluetooth dongle uses.
    Thirdly depending on if you add it to the kernel or as like built in you will have to add the name of the module to a config file which is used when you boot linux.

    If the kernel doesnt have support for your bluetooth dongle then you can either try and find a different copy of the kernel which does or try and find the driver for it.

    To recompile your own kernel however requires a whole guide itself , plus different linux distro's will have different kernels with different options and slightly different config files.

    Only thing i can suggest is going to www.gentoo.org and reading through their handbook, its basically step by step setting up linux manually, in the handbook there is a page or two on recompiling your kernel for your particular configuration.

    Bluetooth Technology Gets Faster With Bluetooth 3.0

    From its annual All Hands Meeting in Tokyo this week, the Bluetooth SIG formally adopted Bluetooth Core Specification Version 3.0 + High Speed (HS), or Bluetooth 3.0. This latest iteration of the popular short-range wireless technology fulfills the consumers' need for speed while providing the same wireless Bluetooth experience – faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect.
    Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers at the approximate rate of 24 Mbps. In addition, mobile devices including Bluetooth 3.0 + HS will realize increased power savings due to enhanced power control built in.


    "Like Ricky Bobby in Talladega Nights, this latest version was 'born to go fast,' said Mike's Blog, Ph.D., executive director of the Bluetooth SIG. "Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers – members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN."

    This newest version of Bluetooth technology builds on the inherent qualities of the current 2.1 + EDR version, including Simple Secure Pairing and built-in, automatic security. And as with all versions of theBluetooth specification, v3.0 + HS provides developers, manufacturers and consumers with the benefit of backwards compatibility, enabling both the expansion and enhancement of this technology with every new specification release. Once products reach the market, the easiest way for consumers to learn which devices are compatible with other Bluetooth enabled devices is to visit the Bluetooth Gadget Guide.

    Applications
    With the availability of Bluetooth version 3.0 + HS, consumers can expect to move large data files of videos, music and photos between their own devices and the trusted devices of others, without the need for cables and wires. Some applications consumers will experience include:
    • Wirelessly bulk synchronize music libraries between PC and music player or phone
    • Bulk download photos to a printer or PC
    • Send video files from camera or phone to computer or television
    Availability

    The Bluetooth SIG's formal adoption of the specification is only the first step in the product lifecycle. News out today from wireless chip manufacturers and Bluetooth SIG member companies Atheros, Broadcom and CSR shows the second step – getting silicon solutions to device manufacturers – is already underway. End products for consumers are expected to be in the market in 9 to 12 months.

    Technical Specifications
    This new specification release includes several major enhancements (learn more here - page requires member login):
    • Generic Alternate MAC/PHY (AMP)
    • 802.11 Protocol Adaptation Layer (PAL)
    • Generic Test Methodology
    • Enhanced Power Control
    • Unicast Connectionless Data
