My computer cannot recognize my calculator's driver and it won't connect to TI-Connect.
Are you using TI Connect CE? https://education.ti.com/en/products/computer-software/ti-connect-ce-sw
Make sure you are plugging the cable into the calculator port firmly and try using a different USB port. Make sure to install TI Connect CE linked above.
If it doesn't show up in device manager, that usually means that either the cable or the calculator is misbehaving. Try performing a full reset on the calculator, swapping out cables and using different ports. What exact version of the TI84+ are you using?
If that's the case you need to completely uninstall TI Connect and make sure that the calculator isn't plugged in when you reinstall.
Unplug the calculator and then push and hold the reset button on the back for about 15 seconds. Then try plugging it back in.
