[alsa-devel] TASCAM US-1800
by amand 01 May '14

01 May '14

Hello! I've just bought a TASCAM US-1800 soundcard. Unfortunately, there is no driver ready for linux. I started to gather some data from the windows USB driver in order to add support in linux. I am ready to invest time in this driver, but this is my first ever attempt. Presently, I try to reverse-engineering the data I have collect with wireshark. Somebody has ever worked on a US-1800 driver for linux ? Perhaps we can get some stuff from the us122l driver... By the way, any help will be appreciated ! -- amand.
