Redoing the command is not a problem for the Sanyo 5500 phonebook or
calendar.  There is no state in the reading or writing of these.

The filesystem seems to work reliably.

Of course it might be a problem for media transfers since the ringers
and pictures are not in the file system.

My phonebook test code worked fine on Windows, using a Futuredial
driver.  (I think the same driver as used for the 4900 and other sanyo
phones.)

If I capture the data with SnoopyPro, the packet I send to the phone is
a single 1034 BULK_OR_INTERRUPT_TRANSFER thingy, but the response comes
back in 4 or 5 groups.  The first set of bytes almost always 99 bytes
which might be followed by 396, 198 and 341 bytes.  These counts will
vary.
