Success. US122 behaves like a normal ezusb device. And the whole USx2x family is using the same loader. I think we are at a point where we can remove that firmware stuff of "us428fw8000.h" and use fxload with an extracted firmware. Ok, a final test on us428 should be done before. Pedro's Tascam USx2x extractor/loader is already here and Clemens is on the way to create an sf project for this wonderful ezusb stuff for MidiSport, Tascam devices (and maybe more in the future). > > * what's the reason of the independent snd-usb-us428-dl module? > this module seems doing only feeding the firmware to the interface, > so why not in snd-usb-us428 itself? this will reduce the use of > inter_module_* stuffs which are obsolete in 2.6 kernels. I think the main reason was a different PCI ID for loading us428fw8000.h. And the other firmware part was originally in snd-usb-us428 IIRC! Ok, removing the sniffed ezusb firmware is a good reason to forget the snd-usb-us428-dl idea completely!
