LINK/DATA TRANSFER NOT WORKING

Quest 3 running Horizon OS 2.7 build 5243367.3600.520 has completely lost USB data functionality. The headset charges but does not enumerate as a USB device on multiple PCs. It also does not offer USB data/MTP when connected to an Android phone. The issue persists in bootloader/recovery mode. Multiple known-good data cables have been tested, including cables that successfully transfer data between phones and PCs. Factory reset and port cleaning have also been performed. When you click on link, it just says "Charge only device connected" for every cable.
