    USB: qcserial: Add support for Quectel EC20 Mini PCIe module · 9d5b5ed7

    It seems like this device has same vendor and product IDs as G2K
    devices, but it has different number of interfaces(4 vs 5) and also
    different interface layout which makes it currently unusable:
    
    	usbcore: registered new interface driver qcserial
    	usbserial: USB Serial support registered for Qualcomm USB modem
    	usb 2-1.2: unknown number of interfaces: 5
