That means the library didn't find any mounted USB mass storage devices.

Not really, unless the volume name is included in the library output.

Drivers are useful if you're trying to interact with a USB 
communications class device (like a USB board that controls some 
external machine or process), but not if you want to read/write data 
to/from a USB mass storage device.

Some USB mass storage devices (specifically some digital cameras) use 
Picture Transfer Protocol (PTP) to transfer images to computers; devices 
that use PTP don't show up in Revs "the volumes" list.

Here's a function based on one written by Dar Scott & Ken Ray a few 
years ago. It will give you more info about available drivers than 
driverNames(). I use it to detect what USB communications class devices 
are connected. Maybe it will help. Watch for line wraps!


function deviceNames
   switch the platform
      case "MacOS"
         return _macDeviceNames()
      break
      default
         answer "Not supported."
         exit to top
      break
   end switch
end deviceNames


function _macDeviceNames
   local theNames="", ioregOutput, skipLines, temp
   local IOTTYDevice, IODialinDevice, IOCalloutDevice
   set the hideConsoleWindows to true
   put shell("ioreg -n IOSerialBSDClient") into ioregOutput
   repeat forever
      put lineOffset("IOSerialBSDCLient",ioregOutput) into skipLines
      if skipLines is zero then return thenames
      delete line 1 to skipLines of ioregOutput
      -- Get all the data between the braces
      put char(offset("{",ioregOutput)) to (offset("}",ioregOutput)) of 
ioregOutput into temp
      get matchText(temp,"\"IOTTYDevice\" = \"(.*?)\"",IOTTYDevice)
      if it is not true then next repeat
      get matchText(temp,"\"IODialinDevice\" = \"(.*?)\"",IODialinDevice)
      if it is not true then next repeat
      get matchText(temp,"\"IOCalloutDevice\" = \"(.*?)\"",IOCalloutDevice)
      if it is not true then next repeat
      put IOTTYDevice,IODialinDevice,IOCalloutDevice & lineFeed after 
theNames
   end repeat
end _macDeviceNames
