Hello All,
I am having similar problem as shown in this thread with EM7565 modem using a raspberry. In my case I have a similar situation as described in this thread: EM7565 stuck in a USB composition without QMI or AT ports
My modem has same VID:PID: 1199:90c3 as described there, so I am trying to update the PID to standard one as described in this thread. However it seems that the modem is not detected over USB interface.
I download the drivers and updated qmi_wwan.c and qcserial.c files to add VID:PID 1199:90c3. Then I installed mbpl driver (EM7565 driver/firmware issue - #10 by jyijyi) and rebooted, but ttyUSBx are not present (if I use a different modem ttyUSBx appear right away)
Checking /sys/kernel/debug/usb/devices I can see there is no Driver associated to the modem
