I finally had the chance to look into my Tascam US-122L’s issue with Leopard last night. It suddenly stopped working after I upgraded to Leopard due to the driver. Tascam has finally released a new version for Leopard and also a new firmware. While installing the driver was easy, getting the firmware updater is a bit of a challenge. I have to get it from the German site, as the english site’s file is corrupt. Oh well, in the end it is working again and I am a happy camper!
I cooked up a simple progression on Garageband and did a little bit of testing with Audicity as well. So far so good!
Thanks to this site for the link from AwkwardDog.com to the German site.
