Hi Levi,
That's an unusual error. If you've wired up your P1 yourself, make sure to follow EEPROM connections like shown in this diagram. If you did wire it yourself, most likely this is a case where something isn't connected as recommended. If you are using something like a Propeller FLiP or some other board that already includes a P1 + EEPROM, then most like the problem is something else, including the possibility that the EEPROM is actually bad or worn out, in which case you'll need to contact @.*** to request an RMA and replacement.

The fact that it downsteps the baud rate first means that it's having trouble communicating with the Propeller, so perhaps it's a board (or self-wired unit) that doesn't have a fast Crystal attached? (ie: it's using the internal fast RC Oscillator only). That could also be caused by a poor-quality USB cable; some don't have very good shielding and may allow for a lot of communication noise.
