Leapfrog Crammer won't mount as a USB flash drive

Solution 1:

Before trying anything too complicated, have you opened Disk Utility and looked to see if the other partitions are listed and just not mounted?

We've seen an increase recently in "flip flop" USB hardware. This hardware (typically things like USB 3G modems or printers) originally registers itself to the host computer as a USB mass storage device (flash drive) containing the driver, and then the driver is able to change the mode of the hardware to access its real functions. I suspect that this may be what is happening with the Leapfrog Crammer.

The piece of software responsible for automatically changing the mode of this hardware in Ubuntu is called usb_modeswitch. In all likelihood, usb_modeswitch doesn't yet know that it needs to change the mode of the Leapfrog Crammer, and may not know how. The usb_modeswitch homepage has documentation on how to modify the configuration to handle new devices
