I mean so that 'Jane Doe' get the LEDs working when she plugs in her wheel... At present the patch uses the devices ID's to register the LED's. ie. -- Mar 14 14:57:35 ubuntu kernel: [ 6462.204185] Registered led device: 0003:046D:C294.0009::RPM1 Mar 14 14:57:35 ubuntu kernel: [ 6462.204251] Registered led device: 0003:046D:C294.0009::RPM2 Mar 14 14:57:35 ubuntu kernel: [ 6462.204301] Registered led device: 0003:046D:C294.0009::RPM3 Mar 14 14:57:35 ubuntu kernel: [ 6462.204354] Registered led device: 0003:046D:C294.0009::RPM4 Mar 14 14:57:35 ubuntu kernel: [ 6462.204402] Registered led device: 0003:046D:C294.0009::RPM5 -- Simon. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
