Quectel RM500Q Connection Issue

Ive just adquired a Quectel RM500Q-GL, but im not able to make it works. I have cloned this git repo following the instructions of the documentation of the web I bought the module. Im trying to use it with a khadas VIM3 board. There is no device in the /dev/ directory pointing to the module but when I write lsusb in the command prompt y see

“Bus 001 Device 003: ID 2c7c:0800 Quectel Wireless Solutions Co., Ltd.”

When I try to launch the QConnectManager in the Khadas board I get the following error:

khadas@Khadas:~/quectel-CM$ sudo ./quectel-CM 
[02-22_17:06:21:631] QConnectManager_Linux_V1.6.2

I hope you can help me soon.

Do I need to install some driver?
