I think a good example of how ALSA should work with USB devices is the gphoto approach.

(I'll need to test that out) The problem I see is how does ALSA access the kernels USB modules and once that is sorted out we need the specs for the devices. So how do we go about writing a "low-level-ALSA-USB-class-driver"? -- Patrick Shirkey - Boost Hardware Ltd For the discerning hardware connoisseur Http://www.boosthardware.com Http://www.boosthardware.com/LAU/Linux_Audio_Users_Guide/ >_______________________________________________ >Alsa-devel mailing list >[EMAIL PROTECTED] >https://lists.sourceforge.net/lists/listinfo/alsa-devel _____________________________________________________________ Want a new web-based email account ? ---> http://www.firstlinux.net _____________________________________________________________ Run a small business?
