Other reviews tell how good this very small Bluetooth dongle is. I agree with this, it is good. This review is about Windows XP installation hopefully to save some grief. If you know how to do this read no further.
Before you start this, you should be in an Administrator account. If you are the only user on your system, you are the Administrator. If there are several user accounts on the system, you need to change yours to be an Administrator or make use of another account that is already on your system.
First you need to check if there is an existing Bluetooth service on your machine, not every body has one. Look at 'Control Panel', 'System' icon, Harware tab, 'Device Manager' button. This shows a list of all the harware and services on your computer. If there is a Bluetooth line already there, this must be removed. Click on the + box to open the lines under the heading. Assuming you have not tried to implement the dongle before this, what you see are the existing Bluetooth services which must be removed. Right click each Bluetooth line below the heading and select 'Uninstall'. Be patient. Repeat this with any remaining lines. Click the red X at the top of the screen, OK on System Properties, red X on Control Panel. Reboot your system and check that the unwanted Blutooth items are gone by repeating the procedure.
This Bluetooth USB dongle and the associated software need to be installed on a clean boot machine; any application that gets in the way and the installation is not complete.
To achieve a clean boot is technical but not that difficult. You need to simplyfy your system configuration for a short while and return it to the original configuration afterwards. This is done using MSCONFIG.
On Windows XP, click 'Start' to open the programs window. In the right column there should be a link that says 'Run'; click this once and a small window will open for you to type into. Type msconfig (caps not necessary) and click OK. This will bring up a strangely technical window with many tabs. Select the 'Services' tab by cliking on it. At the bottom of this window is a box with the words 'Hide all Microsoft Services'; tick this box then click on the 'Disable All' buttton: this will disable all the services except the Microsoft ones that you need. Remove the tick on 'Hide All Microseft Sevices' to bring them back. Then click on the 'Startup' tab; this shows a list of applications that start up when you log into your system. If all the lines are ticked, then just Disable All. Alternatively, if you may have carefully selected a few necessary items previously (perhaps with other software), the rest being blank to speed up your sytem: in this case write these items down so that you can find them later before the 'Disable All'. Finally press 'OK' once at the bottom of the window; it will be slow to respond, just be patient. It might give you a message to remind you that you need to be an Administrator to do this; provided that you checked this out before hand, ignore this window and carry on. It will open a window giving the option to retart; select this.
After the restart, log into the Administrator account that you had used earlier. You should get a strange warning window about changes, click the box not to show the msconfig window again and OK. You are ready to install your Bluetooth. Follow the procedure as shown on screen, it will tell you when to fit the dongle. Use a USB port at the back of the PC / laptop and do not use a hub even if it has its own power. Note that this little dongle is a tight fit; get it the right way up and push hard so that it is fully in; once in don't ever think of removing it. When the installation is finished, leave you PC / laptop for a few minutes for windows to recognise all the hardware configurations that have been implemented. When all this has finished (basiclly Windows has stopped recogising hardwares), reboot your system for the end of the Bluetooth install.
When the Bluetooth installation is finished it is time to reset the system configuration using MSCONFIG. Basically you will repeat the procedure above but this time you will 'Enable All' the 'Services' and the 'Start Up' tabs. If you had a subset of start up items, use the list you wrote down earlier. Just tick the selected items. This time they are all in alphabetical order so you will have to seach for them; note that some items occur several times, make sure they are all ticked. The Bluetooth and Broadcom items should already be ticked but check this, no need to press the 'Enable All' button in this case. Finish with the OK button and reboot your system again.
