EC25 | Device not getting via adb devices

Hi All,
I have purchased EC25 development kit.
And connected to Ubuntu 14 host ,but device is not getting using via adb devices command.
created file adb_usb.ini in .android directory and wrote usb vid 0x2c7c .
what might be the reason.
Regards
Richu

what does “lsusb” tells you?
Did you added the Vendor specific Changes to Kernel as described in Driver manual?

Regards,

Brian

HI Puck,
I have a important question, pls help.

With new module EC25E(EC25EFAR06A11M4G) that bought from quectel.
Can I use ADB shell or not ?

But i encountered a issues that when i received a EVB from local FEA , I can use ADB shell, but after i have a new module and soldered on PCB, i see that, i can’t use ADB shell any more.
Are there any errors here or must use QuecOpen to open ADB shell

thank you
