No, I cannot. But I can say that it doesn't match the Gobi1k or Gobi2k layouts. > How to add VID/PID pair to the kernel driver and recompile it? You don't need to do that just to test. A QMI function needs 3 endpoints, so first try to find out if any of the unknown USB interfaces have 3. "lsusb -vd 19d1:fff1" will tell you this. For example: Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 3 bAlternateSetting 0 bNumEndpoints 3 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 255 Vendor Specific Subclass bInterfaceProtocol 255 Vendor Specific Protocol iInterface 0 means that interface #3 has 3 endpoints and is a suspect. Then unbind this interface from the option driver and dynamically add the device ID to qmi_wwan: echo 2-1.2:1.3 >/sys/bus/usb-serial/drivers/option1/unbind modprobe qmi_wwan echo 19d1 fff1 >/sys/bus/usb/drivers/qmi_wwan/new_id This should make qmi_wwan bind to interface #3 instead of option. You can now use libqmi tools to probe the /dev/cdc-wdmX device. Or let MM probe it if you built MM with QMI support. Repeat for every unknown (i.e not successfully probed by MM) interface with 3 endpoints.
