插拔模块，dev目录无变化，不能使用at指令
what did you see in dmesg?
how about adding this?
echo 413C 81CC > /sys/bus/usb-serial/drivers/qcserial/new_id
Thank you very much. I have changed DW5816e to the universal EM7430. As for the driver, I forced it to be installed under Windows and then changed it using the at command. It was perfect. Thank you!
I still have two EM7430 vid 1199 pid 9076, which should be on Panasonic computers, and I am working hard to resolve them.
Hello, I have three modules. Two of them have been successfully modified, but one module only outputs “error” when using the command AT!ENTERCND=“A710”. Has the password of this module been changed?

yes, i think so, you need to enter the correct password
I don’t know the password. Is it a situation with no solution?
you need to ask the owner of this module
Is there a method to force firmware updates? Or force a factory reset?
what did you see in device manager now?
BTW, have you tried in linux?
i don’t know, you can try it or try in linux
