If I remember correctly, over IRC you said that a grep of messages for i2400m only turned: Jul 22 16:20:03 x201 kernel: i2400m_usb: probe of 2-1.3:1.0 failed with error -22 It that's the case, I missed to make the code properly report an error condition, and we need to find out which one is it. Can you enable debugging?: 1. unload the i2400m and i2400m-usb modules 2. $ modprobe i2400m debug='driver:8 control:3' 3. $ modprobe i2400m-usb debug='usb:8' that should be printing way more logs to the console
