Vec pola godine imam neki USB Bluetooth modul "Eracom".
I pravilo prilikom instaliranja glasi: {Prepricavam} Prvo instalirajte Ove drajvere sa CD-a, kada vam bude bilo zatrazeno da konektujete Bluetooth na racunar, otkazite i nastavite instalaciju. Tek kada se instalacija zavrsi, konektujte bluetooth i pustite da se instaliraju Windowsovi drajveri. Ako prvo ubacite Bluetooth i instaliraju se Windowsovi drajveri, a potom ubacite CD i pokrenete instalaciju ovih drajvra, uredjaj nece raditi. Tako i jeste, ja sam slucajno ubacio Bluetooth, pre instalacije Drivera i programa sa CD-a i posle, kada pokusam da pokrenem Bluetooth, pojavi se greska, u smislu da trazi neki Licence kod, koji ja nemam............

Pitanje:

Kako mogu da Uninstalliram drajvere, koji se automatski pokrenu prilikom prvog konektovanja bluetootha na racunar? One koje Windows sam instalira? Jednom sam to uspeo da uninstaliram i posle normalno radi,ali se ne secam tacno...

I ja sam imao takvih problema...

Probaj da obrises iz desni klik na mycomputer pa propertaris pa hardware i onda device manager. Tu nadji drajver i obrisi.

Ja sam imao isti problem sa wicomm drajverom,ali to je do SP2 koji ne da da se instalira ništa jer je kao njohov drajver pametniji.Na nekom forumu sam pronašao rješenje pa ću ti ga dat milim da će upalit i kod tvog problema.


Moguće je da ti SP2 na WinXP jebe drivere od Bluetootha. Odinstaliraj
Bluetooth i ponovo instaliraj prema uputstvima ispod. Kvaka je u tome da
povučeš pravi driver s instalacijskog CD-a umjesto onog kojeg su instalirali
Windowsi, i da disejblaš Windows drivere da se podignu kad resetiraš sustav.
Jednostavno je, samo slijedi upute.

In the Service Pack 2, Microsoft included a generic Bluetooth driver,
naturally being WHQL-certified -- it's directly from Microsoft. The WIDCOMM
Bluetooth driver however is not WHQL-certified, so windows XP continues using
the generic driver. This interferes with the WIDCOMM Bluetooth software
resulting in the above error.
You can force Windows XP to use the WIDCOMM driver by following the steps
below:
1. Disconnect the Bluetooth Dongle from the USB port
2. Uninstall the WIDCOM Bluetooth Software
3. Restart the Computer
4. Install the WIDCOMM Bluetooth software. When asked to plug in the Bluetooth
device and click OK, don't do it. Instead, click Cancel.
5. After the WIDCOMM setup has finished, connect your Bluetooth device and let
Windows install the driver. There should be two Bluetooth icons in the system
tray:
a) One blue-white: this is the Windows driver, and
b) One blue-red: this is the deactivated WIDCOMM driver
6. Open the Device Manager, right click on the "Generic Bluetooth Radio" and
select "Update driver". Don't let Windows XP connect to the Internet, select
"Choose software from a list or specified location".
7. In the next window, select "Don't search, but select the driver to
install".
8. In the next window, activate "Show compatible hardware" (if it isn't
activated already) and point to the driver on the CD driver (e.g. CSR) instead
of the "Generic Bluetooth Radio" driver.
9. Click next until the new driver is installed.
Now the WIDCOMM system tray icon should be blue-white as well, activated and
ready to use. If you now double click on "My Bluetooth Places" (e.g. on the
desktop), the WIDCOMM software installation will be continued and finished.
After doing this, you might want to consider renaming "C:\WINDOWS\INF\BTH.INF"
to something like "BTH.INF.BAK" so that the Microsoft stack doesn't get
reinstalled.

Uspeo sam!
Hvala na pomoci! 

odlično,to je nama naš SP2 dao.
