HISTORY
The uslsa driver appeared in NetBSD 4.0.

AUTHORS
The uslsa driver was written by Jonathan A. Kollasch. Code and style was borrowed from existing NetBSD USB-serial drivers. Due to the unavailability of documentation, Craig Shelley's reverse-engineered Linux driver was used as documentation.

CAVEATS
Hardware flow control may not work correctly.

Settings other than 8 data bits, no parity, and 1 stop bit seem to be refused by the chip.
