New AC68U running Merlin 376.49_5. Running fine except for a quirk with the USB3 port. The router does not see either of my external USB3 drives when they are attached to the USB3 port. Sees them fine on the USB2 port, no problems streaming music to my receivers. The USB3 port seems to be functional, I plugged in a USB stick and I saw it. The powered external USB3 drives are formatted NTFS, nothing unusual. Not a big deal, just using the USB ports to stream music from the external drive. Just wondering if anyone has encountered this problem and was able to solve it. I do understand that the Asus routers can be touchy with attached drives. Thanks, Steve
