[ Please CC me as I'm not on list ] Hi, I have an M-Audio MobilePre, it's a USB audio module which works with snd_uadio, however to get it working I need to load the firwmare (via DFU).
Unfortunately the only way I can get it to re-enumerate after sending the firmware is to unplug it enough to disconnect the data lines (but not power) and then reconnect. I have tried usbconfig reset, power_off/power_on, set_config and set_alt but to no avail..
