Won't work.  LocalTalk on the Mac is only supported through the built-in
serial ports.  It depends on the hardware support provided by the Zilog
Z8530 SCC chip to implement the bit-synchronous HDLC framing, and is
very timing critical.

A USB-Serial adaptor wouldn't be able to handle it without corresponding
serial hardware and implementing the low level parts of the AppleTalk
stack (at least the LLAP driver) in the peripheral.
