[Q] USB Only Charging, No Other Connection Types Working topic

I have been fighting this for awhile now. My phone boots up just fine, and I am able to charge it through USB, but I cannot get Windows to recognize it. I have tried multiple ports, checking and unchecking MTP and PTP in settings, enabling and disabling ADB, and even putting the phone in download mode. LGNPST won't even recognize it in download mode. I'm really not sure what to do at this point. Does anybody have a suggestion? I'm currently running CWM 6.0.4.7 and CM 11. Thanks in advance for any help.
