Unfortunately I cannot assist you here. I mostly write my own firmware. You
could try requesting a skeleton firmware from Silicon Labs. and then
modifying it to suit your needs. Afterall, a Mass Storage class device is
only different from a HID device because the device and interface
descriptors say they are. The default Windows XP drivers, for example,
support Mass Storage class devices by default.

The firmware generator might not create the string descriptors required,
even if it would create a solid skeleton firmware for a Mass Storage class
device. The Device, Configuration and Interface Descriptors make use of a
String Descriptor table that presents the human-readable strings which an
operating system shows during device enumeration. These strings dictate
manufacturer name, device name and possible device version etc. Make sure
these strings are correctly initialized and set (they are UNICODE strings).
