Flash Memory Update/USB Connection Issues in POD HD Posted May 25 Hi guys. Just to let you know that I've also solved my issue by replacing the USB Controller chip and the USB Port. This topic was very helpful and I hope all of you can solve your problem as well. I bought a CY7C68013A-56PVXC (I didn't buy it directly from the Line 6 distributor, I bought it from ebay) and it worked nice. For those who believe it wouldn't work because it should have a firmware pre instaled, actually it needs a firmware but the firmware isn't located in that part so you don't need to be worried about buying directly on any Line 6 distributors.
