and yet to check with Salix 13.1.2. Report back soon ,-) There is a bug report at https://bitbucket.org/ahixon/r5u87x/issue/26/ in this connection.
What I did in Ubuntu was, I commented out the { 0x05CA, 0x1870, 0x0112, 0, 0 }, // Used for HP Pavilion dv1xxxx (1870.fw) in loader.h and recompiled. and it worked well.
