   I found out why my device won't see the SD card. But first:   
      
   I can't update the onboard eeprom without using the imaging tool, that's   
   apparently by design. The CM4 won't let you touch that stuff because   
   it's "impossible to remove the eMMC if something goes wrong." Makes   
   sense, but still a PITA for those of us not using the thing in production.   
      
   However, the real reason I'm having all these issues is because, after   
   inspection, my vendor sent me the 8GB eMMC version instead of the no   
   eMMC version I asked for. That sucks because I don't really want storage   
   I can't ever change because it likes to go bad, but there it is.   
      
   I believe the reason the device won't USB boot on the MCUZone carrier is   
   because it is indeed going into panic at boot - I've seen some   
   information about the USB device on this being problematic.   
      
   My next step is to try and flash the eMMC on this one the see what   
   happens. I'll let you know.
