The 245 is described as a "FIFO" and the VCP driver is a VirtualComPort
driver, whilst the 232 is "UART".
Don't know the actual difference as such, but the 245 seems to be able to
handle higher speed.

Correction, there is a 245 that is paralell as well.
So they have two different 245, 245R, paralell FIFO and 245BM/BL/BQ SERIEL
FIFO
