Hello. I am a clueless n00b, and I can't make patches or use any proper development tools. But I made this modification to t613.c to support this new sensor. It is working fine with me. I just cleaned the code up a bit and compiled and tested with the 2.6.32 kernel, and it seems to be working fine. If somebody could help me creating a proper patch to submit to the source tree, I would be most grateful. The code is attached. Thank you, ++nicolau -- Nicolau Werneck <nwerneck@xxxxxxxxx> 1AAB 4050 1999 BDFF 4862 http://www.lti.pcs.usp.br/~nwerneck 4A33 D2B5 648B 4789 0327 Linux user #460716
