Yes. I just tried the firmware update again. It didn't work. Then I re-plugged the unit and the update still didn't send. Then I power-cycled the unit. And the firmware update sent OK. So I thought, why not try sending some saved midi data. OMG! The slider moved. So I connected ardour, and everything's working OK. Since then I've re-plugged it, power-cycled it, removed and re-added the alsa modules. And it's still working. I've struggled with this thing for 2 weeks, and it starts working again now, of all times. And I didn't do anything differently. Maybe it was the incense I burned last night... :-\ > I guess re-plugging the device doesn't help? This is what happened (before it started working again, obviously): ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:215: sending packet: [ 1b be 7b 00 ] ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:190: urb status -32 ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:215: sending packet: [ 1b bf 7b 00 ] ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:190: urb status -32 ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:215: sending packet: [ 0f ff 00 00 ] ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:215: sending packet: [ 0f ff 00 00 ] ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:190: urb status -32 usb 1-4: USB disconnect, address 4 usb 1-4: new full speed USB device using ohci_hcd and address 5 usb 1-4: configuration #1 chosen from 1 choice ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:215: sending packet: [ 0b b0 07 43 ] ALSA /usr/src/alsa-driver-1.0.11/usb/usbmidi.c:190: urb status -32 If there's anything else I can do to help, please let me know. bye John _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
