I have the interface up an running but it does not recognize my USB Drive. I have the wireless connected and have update both Control and Interface Firmware to the latest version but the bottom left of Interface show "no usb drive." The Drive light on Interface is also not illuminated. I have formatted two different drives (including the one that came with Interface) with FAT32 and prepped them using the wizard in Control. I have checked the USB port on Interface and it does not appear to have any buildup pr foreign particles in it. Everything else seems to work fine outside of I can't get it to recognize any USB drive. Any help would be appreciated.
