I just plugged them in and no lights, no indicators at all. SimDash recognizes when I start iRacing but when I click on configure for the GI-Max and SPI-D the SPI-D says either the device isn't connected or I need a firmware update. I updated the firmware to the SPI-Dv3 but nothing changed.
My pc sees both the devices but lists them under the category of Unspecified.
