OK - in the interest of proper testing, I reset one of my 68U routers, reloaded 384.5, factory reset, reformatted the 2.0 USB drive on a linux box, then went thru the router setup (including Samba and ftp), removed and replaced the USB drives (both 3.0 and a 2.0 - and yes, plugged into the proper ports...). 3.0 is seen and works, 2.0 not seen by the OS (blue light is on). Then did the toggle trick, rebooted... Still no good. Reformatted 2.0 as a fat, rebooted... still no good... Logs show nothing for the 2.0 on insert, removal...
