Connect your Bluetooth card to your laptop and then transfer it to your PC.
Confirm the connection is stable and the driver is properly installed. Test the USB port with another device to ensure it works correctly. Avoid using improvised tools for data connections, as improper soldering can cause issues. If you haven’t maintained the setup recently, it might affect performance.
I observed the Bluetooth card running hot. After confirming the 5V cable is supplying power, everything seems fine. You haven’t used a soldering iron for the data lines, and the USB port functions properly. Devices have worked before and after making these changes.
It appears there was an error in the setup: this Bluetooth USB operates at 3.3V instead of 5V. It’s likely the Bluetooth component was disconnected. If you still wish to attempt it, you can convert 5V to 3.3V using a regulator available on eBay, or simply connect an orange wire from your PSU (3.3V) if your power supply is inexpensive. I don’t advise doing this with a high-quality PSU.
You're confused about why it wasn't designed for 5V instead of 3.3V, and you mentioned having a USB source but not a 3.3V one. It's okay—Bluetooth works fine even without the right voltage. If you ever need something like this, buying a compatible device is now easy and affordable. Thanks for your patience and for sharing your thoughts!
