2. Delete the following files:

p>

C:\\Windows\\system32\\drivers\\bthenum.sys, Bthusb.sys, Bthprors.cpl; (maybe not, depending on whether the built-in driver has been installed)

C:\\Windows\\system32\\Fsquirt.exe

C:\\Windows\\inf\\bth.inf, bth.pnf, bthpan.inf, bthpan.pnf, bthprint.inf, bthprint.pnf, bthspp.inf, bthspp.pnf.

3. Find btwusb.inf in the Bluetooth driver directory and add your device ID in [ControlFlags]. The format is consistent with the one inside. ExcludeFromSelect = USB\\VID_045Eamp; PID_009c;

4. Add MSFT.DeviceDesc=BTWUSB with the same format in [WIDCOMM.NTx86.5.1],

USB\\VID_045Eamp; PID_009c; Microsoft save;

5. In; Add the same format MSFT.DeviceDesc=BTWUSB in [WIDCOMM] after Win2k specific sections,

How to modify the IVT2.3 Bluetooth driver

1. Unplug Microsoft Bluetooth Adapter (do not plug in the newly installed system);

2. Delete the following files:

C:\\Windows\\system32\\drivers\\bthenum.sys, Bthusb.sys, Bthprors .cpl; (maybe not, depending on whether the built-in driver has been installed)

C:\\Windows\\system32\\Fsquirt.exe

C:\\Windows\\ inf\\bth.inf, bth.pnf, bthpan.inf, bthpan.pnf, bthprint.inf, bthprint.pnf, bthspp.inf, bthspp.pnf.

3. Install IVT2.3 and crack it

4. Plug in the Microsoft Bluetooth adapter. The system will prompt that the driver cannot be found. The device manager is an exclamation mark. Right-click the exclamation mark of the device and select Properties. , detailed information, device example ID, look at this USB\\VID_045Eamp;PID_009c;

5. Open C:\\Program Files\\IVT Corporation\\BlueSoleil\\driver\\usb\\btcusb .inf, add your device example ID at [ControlFlags] in the same format as ExcludeFromSelect = USB\\VID_045Eamp; PID_009c; add the same format as CSR.DeviceDesc=Btusb_DDI, USB\\VID_045Eamp at [IVT]; PID_009c, save;

6. Open C:\\Program Files\\IVT Corporation\\BlueSoleil\\bttl.ini, in; changed to add sending reset hci mode to hid mode dongle command

Change the ID at [HW4] to your device example ID (ID=USB\\VID_045Eamp;PID_009c); this is CSR HID dongle mode dongle ID. While detecting this ID,

; BlueSoleil will call hid2hci.exe to change mode to HCI mode.

Add your ID (ID=USB\\VID_045Eamp;PID_009c) at [HW50], and change num=4 at [SWITCH2MODE] Add HIDUSB2 = USB\\VID_045Eamp;PID_009c, followed by 1234, save;

7. Update the driver of the device and install it from the list or specified location. Do not search for the driver to be installed. When installing from disk, IVT Corporation\\BlueSoleil\\driver\\usb\\btcusb.inf will prompt that the driver found does not have a Microsoft signature. Regardless of the prompt, the driver installation is complete

The first paragraph was researched by me. Because I couldn't find the method to modify the BTWwidcomm Bluetooth driver on the Internet, I installed it myself and gave it a try. It's mainly a Bluetooth ID problem. Check if there is an exclamation mark or question mark in the device manager. You should be able to follow the method I mentioned above.
