I just bought an Inland USB Parallel Converter from MicroCenter for about $10 and on the package they claim: "Fully compliant with USB specifications version 1.1, Provides bi-directional ECP function, supports standard PC parallel port register-based operation,... Maximum throughput: 1.2 Mbps (ECP mode)..." Does this info help? I'm trying to get a Powerbook to use a parallel printer. This should be fun...
