I have a TV with ROKU built in..it works fine with my external. I bought 1 for my TV in living room it won't pick up external??? The ROKU built in TV will pick up the USB device but the other ROKU express I bought for the living room will not! It doesn't show the USB connection?
Is there something I may have overlooked with the express?
Yes, a lack of a USB port on the Express, you can't use the non-Roku tv usb port on a roku that is simply plugged into the same non-roku tv!! Only true Roku TV's and Roku Ultra have USB ports, sorry.
