I am using an EP06-E LTE modem and decided to upgrade the firmware from EP06ELAR03A08M4G to EP06ELAR03A09M4G.
I noticed that now the modem is no longer recognized as 1-1 but as 2-1 and consequently it is not detected by your firmware.
De facto, I had to ask this question to make the switch from USB 3.0 to 2.0.
gl_modem -B 2-1 AT AT+QUSBCFG=\"SS\",0
Except that I’m often remote and I can’t execute this command after a reset!
Can you update the 4.2.1 firmware?
