Karsten Wiese's patches are making their way into the ALSA driver, from v1.0.18rc1 (check the changelog).
Unfortunately I have an US-144 for testing...
I first compiled Kernel Vanilla 2.6.25.4 under Ubuntu 8.04 Hardy Heron following Federico Briata's tutorial.
I then tried to modify snd-usb-us122l_0.5.patch l.771-781
Code:
+static struct usb_device_id snd_us122l_usb_id_table[] = {
+ {
+ .match_flags = USB_DEVICE_ID_MATCH_DEVICE,
+ .idVendor = 0x0644,
+ .idProduct = USB_ID_US122L
+ },
+/* { */ /* US-144 maybe works when @USB1.1. Untested. */
+/* .match_flags = USB_DEVICE_ID_MATCH_DEVICE, */
+/* .idVendor = 0x0644, */
+/* .idProduct = USB_ID_US144 */
+/* }, */
into
Code:
+static struct usb_device_id snd_us122l_usb_id_table[] = {
+/* {*/
+/* .match_flags = USB_DEVICE_ID_MATCH_DEVICE, */
+/* .idVendor = 0x0644, */
+/* .idProduct = USB_ID_US122L */
+/* },*/
+ { /* US-144 maybe works when @USB1.1. Untested. */
+ .match_flags = USB_DEVICE_ID_MATCH_DEVICE,
+ .idVendor = 0x0644,
+ .idProduct = USB_ID_US144
+ },
Even after multiple replugs and reboots, dmesg outputs
Code:
snd-usb-us122l: probe of 5-5:1.1 failed with error -5
with an additional "couldn't __get_free_pages()" error message (generated from sound/usb/usx2y/usb_stream.c)...
Might be due to my patch mashup.
I also tried to compile this latest ALSA driver version (--with-cards=snd-us122l among other configure flags), but no related module gets built. The changelog reads "build stub for us122l", hence probably still some inactivated code snippets...
I guess I'll go fetch a Native-Instrument Audio Kontrol 1 tomorrow...
Good luck!
