This is targeted to owners of a non Chumby One device.
The script does not install any file and does not attempt to modify the firmware.

The utility has been updated and those users who got a negative report may get a different result with this one.
Also a new version (1.5) has been added here
It provides a direct feedback on the Chumby by showing messages during the test.
It may turn out to be useful for those users who can't find the install.log on the USB key after running the test. This happens if the key is formatted as NTFS and sometimes even with FAT32: the Chumby mounts it as read only thus blocking any writes.
Read the README file for the available options.
