i have a EM7330,the DM port and NMEA port can be detected by device manager normally,but have no AT command response.The hardware ID is:USB\Vid_1199&Pid_9041&MI_03.
for good sample,the hardware ID is:USB\Vid_1199&Pid_9041&Rev_0006&MI_03.
What’s the “Rev_0006” here?
What’s the possible rootcause for “Rev_0006” lost?
Can i modify the hardware ID?
Can you help on this? Thanks!
