I am using Quectel gsm module on Arm board from olimex. While attaching the Device via USB, dmesg shows following:

*qmi_wwan 2-1:1.0: not on our whitelist - ignored*

*what does it mean?*

We can definitely agree that this was not an informative or good message. Luckily it was removed from the driver with commit 03304bcb5ec4 ("net: qmi_wwan: use fixed interface number matching") more than 4 years ago... It would help if you said which kernel version you were using when asking about such things, especially when the kernel is as ancient as this. That message only ever appeared in v3.4 and v3.5, and was mostly useless noise. The driver had a per-device whitelist of supported interface numbers before we got interface number matching in the USB core. For some reason, I thought it was a good idea to inform about the non-matching interfaces. Don't know why. Probably too little thought involved in the process. The current meaning of the message is that you are using an too old version of the kernel/driver :) Bjørn
