I have an Asus B550-F ROG Strix (Wi-Fi) motherboard and the front USB ports of my case and the USB ports except the 2 lower ones on the rear of the motherboard have issues detecting my iPhone 12 and if it does detect it my PC won't detect any folders or files in my iPhone 12 or once in a while will detect a few files but not all. I connect my iPhone 12 to my PC via USB to import photos onto my PC. I tested my old iPhone 5 SE and I don't have that issue with it. I really want to use the front USB ports of my case for devices I connect temporarily but I can't do it with my iPhone 12 due to this detection issue. All other device I tried have no problems with detection with those USB ports, just not my iPhone 12. I tap on Allow on my iPhone but the it detects the phone but not the folder or files and if I try to reconnect it won't detect my iPhone 12 at all. Does this sound like a compatibility issue with the B550 chipset with the iPhone 12? Is there something different about the 2 lower USB ports on the rear of my motherboard compared to the rest of the USB ports of the motherboard including the front USB header? I'm using Windows 10 Pro and have the latest BIOS version and latest chipset drivers installed. Also my older PC with a X79 Chipset motherboard and my NUC does not have this issue with my iPhone 12 through USB connection.
