Get modem status - can’t read modem information,
AT command can’t run,
View EM7565 version information from the adapter board as follows
Is there any way to repair it
seems your USB driver has problem, are you installing GobiSerial driver?
What did you see in dmesg about the ttyUSB port?
H i jyijyi
The GobiSerial driver has been installed OK
No information about the ttyUSB port is displayed
then that means USB port cannot be enumerated when USB cable connected to the host.
Here is my test on Ubuntu PC:

So are you trying to perform a PPP dial up through the AT command port or are you trying to use the RMNet interface (at!scact=1,1)?
As @jyijyi hs has there is no information on the ports being enumerated on the system, the AT command port is normally the third port that comes up you are using a ttyS0 or at least ttyUSB, I would have expected it to be ttyUSB2 as the AT command port for you to run the gstatus command you are trying with.
Use the RMNet interface，Do you have any good instructions for me。
if the GobiNet driver is working, you can use QMI SDK instead of AT command to start the rmnet interface.
Try the attached file.
