[Lcdproc] VLSYS L.I.S 2005 Driver written

[Daryl F]

  I wrote a driver for the L.I.S 2005 (not the L.I.S 2) by tracing the
USB traffic on a WinXP system with VLSystem's (vlsys.co.kr) driver and
application running. I've inquired with them if I can release the driver
to open source but have received no response.
  Can I release this driver for lcdproc without their permission? Does
it break copyright law to trace a datastream and write a driver without
decompiling or disassembling their programs?

Thanks,
Daryl
