I have an ASUS Sabertooth Z97 Mark 1 motherboard.
When I first set up the computer, I remember that the USB Charger + feature of AI Suite III detected my iPhone without issue.
Now, 1.5 months after setting up the computer, I just receive a Device not found message. I can confirm that the cord is plugged into the white-outlined USB port (labeled USB flashback). I have tried uninstalling, cleaning, and reinstalling AI Suite, I have tried rolling back all my USB drivers, and neither has worked so far.
I have another USB-related issue involving this motherboard and the UEFI BIOS; if I press del to enter bios on startup, and have my razer mamba 2012 plugged in, the bios freezes. If I unplug the mamba, I can use my keyboard to navigate the bios. This is an ongoing issue: ASUS wants me to RMA the issue away, but I'm not convinced that will actually solve anything. I'm talking with razer as well to see if the issue is (as I believe) software-related. I only mention this issue because it's also USB-related, and therefore might be connected to my USB Charger+ issue.
