_______________________________________________________
Details:
There is a bug in usbtiny_paged_load() that causes a read/verify operation to
overflow the flash memory buffer and crash the application.
The chunk being read is always 128, regardless of the actual bytes requested
or bytes left.
See patch.txt for details.
