Hog 4-18 constantly going to Login and not going to hog software

I am working on a show and an hpu did that this morning.  We are using 4.2  I noticed that it wouldnt see any jump drives i plugged into it.  So i restarted and i got the hog4 login screen.  I was able to use a full install to get the hpu working again.   I replaced it with a rackhog and a dp8k.  And rebuilt the show.  Then about 10 hours later it did the same thing!!!  I would love to know what is going on.

Do the USB cards show up as "BOOTLOADER" in the file browser on your HPU?  In some cases, we have observed an issue with the driver for the V1 USB cards and we have a solution if that is the case here.
