Hey guys, I contacted Sound Devices at sounddevices.com about writing a Linux driver (I was going to head the project but would take any help I can get) for the USBPre, a 2ch-in 2ch-out USB preamp with highquality balanced XLR Mic inputs.
They said that they would love to have a Linux Driver and will provide specs for me, I am still waiting on the info though. I have not asked if I can view their firmware sourcecode yet, and if it requires an NDA, I will have to work around that. What advice do you have for writing a driver for alsa? I have written some small kernel drivers for embedded Linux devices, a few audio programs in C, and I come from a DSP background, but I am not sure exactly where to start, besides the specs and firmware.
Thanks for your help
