MT7612U WiFi USB dongle that start ad CDROM (contain Windows driver)

[Menion]

Hi all

I have just received a chinese USB dongle based on Mediatek MT7612U
that is quite particular...

When plugged in it starts with VID_0E8D&PID_2870 showing itself as a
SCSI CDROM, which can be mounted and contains the windows driver. In
windows, once you install such driver, it switches to the well known
VID_0E8D&PID_7612 detected as a Mediatek adapter and working ok.

In Linux of course it remains stuck at the "CDROM mode".

Is it something known at mt76 development and that can be managed?

This is usually handled by the usb_modeswitch utility. Do you have it
installed? If you do, you may need to add the USB IDs to it.
