The ES58X devices has a CDC ACM interface (used for debug purpose). During probing, the device is thus recognized as USB Modem (CDC ACM), preventing the etas-es58x module to load: usbcore: registered new interface driver etas_es58x usb 1-1.1: new full-speed USB device number 14 using xhci_hcd usb 1-1.1: New USB device found, idVendor=108c, idProduct=0159, bcdDevice= 1.00 usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1.1: Product: ES581.4 usb 1-1.1: Manufacturer: ETAS GmbH usb 1-1.1: SerialNumber: 2204355 cdc_acm 1-1.1:1.0: No union descriptor, testing for castrated device cdc_acm 1-1.1:1.0: ttyACM0: USB ACM device Thus, these have been added to the ignore list in drivers/usb/class/cdc-acm.c N.B. Future firmware release of the ES58X will remove the CDC-ACM interface. `lsusb -v` of the three devices variant (ES581.4, ES582.1 and ES584.1): Bus 001 Device 011: ID 108c:0159 Robert Bosch GmbH
