While there are many USB-serial cable
manufacturers, there aren't nearly as many USB-serial chip
manufacturers. FTDI and Prolific are two of the most common chip manufacturers, so most cables use either an FTDI or Prolific chip. For instance, the cables we sell use the Prolific chip. IOGEAR cables also use the Prolific chip, whereas Sabrent cables use the FTDI chip. This information should be available from the cable manufacturer or vendor.
