mackrackit,

My project is going well. Without your help I would be still stuck trying to make this SDFS work. Thank you for your help.

After a lot of reading, I figured out a way to make USB and SDFS work. I had to modify the 18F4550.bal file. There are two versions of this file, one for USB and one for non-USB devices. The option for USB devices had some memory settings commented out. I enabled back these settings and BINGO, it worked.
