Hi John,
The USB Mass Storage (ums) works in Windows, Linux and OS X (EL Capitan). But, not in OS X (Yosemite). By applying the said patch, it extends the ums support.

The test what I did is like this:
Linux: - Run ums to expose all my eMMC partition - shows all correctly - Run ums to expose only 1 partition of my eMMC - show correctly
Windows: - Run ums to expose all my eMMC partition - it detects but it prompts, if I want to format it (due to a non windows partition) - Run ums to expose only the FAT32 partition - it show the partition correctly.
Note: I have a patch to expose only 1 partition: e.g: ums 0 mmc 1:8
