Hi, I work on connecting a cellular module (with H24 Telit component) using an USB interface to our Yocto distribution. The /dev/ttyACM0 interface is not mounted on the Yocto distribution I use following USB connection. Here are the dmesg logs: [65133.056335] usb 2-1: new high speed USB device using musb-hdrc and address 2 [65133.214965] usb 2-1: device v22b8 p2d91 is not supported [65133.220520] usb 2-1: New USB device found, idVendor=22b8, idProduct=2d91 [65133.227508] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [65133.234924] usb 2-1: Product: Motorola Phone (H24) [65133.239929] usb 2-1: Manufacturer: Motorola, Inc. [65133.274108] usbcore: registered new interface driver cdc_acm [65133.280029] cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters
Maybe the used cdc-acm driver is not the right version. Would you know which cdc-acm driver version I should use please? How is it possible to change/upgrade the cdc-acm module? Would you have any advice to help me please? Thanks for your help. Regards, Simon Andrieu
