Quoted from genex:
Thanks for the input - gonna go buy an old school 2.0 USB and hope it works - the operator I am working with this on had mentioned he has a lot of issues updating the code on the JJP games so this must be why. Guess if we find one that works we'll designate that for all his JJP machines
Updated Houdini on one of the USBs we tried for JJP and it worked fine so must be one of those compatibility things...
These are the drives I'm using and having no issues so far:
You can get the kingston drives at Fedex office stores and maybe walgreens or CVS.
