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 lsusb output: Bus 002 Device 003: ID 05c6:9215 Qualcomm, Inc.
