![]() ![]() cdc_acm 2-1:1.0: ttyACM0: USB ACM device usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 2-1: New USB device found, idVendor=16f9, idProduct=0003 usb 2-1: new full-speed USB device number 4 using ohci-pci With cdc_acm driver, dmesg and lsusb output is: $ dmesg It works fine on Windows 8+ using the usbser.sys driver. It seems to prevents the device from working properly (a GBA ST2 Bill Validator using ccTalk protocol). My issue is that only the Communication interface is being assigned to /dev/ttyACMX by cdc_acm driver, but the Data interface is ignored. The CDC Communications and Data interfaces are shown respectively on 2-1:1.0 (Comm) and 2-1:1.1 (Data) interface descriptors, and the cdc_acm driver is being loaded properly. I have a USB CDC-ACM device emulating Serial over USB communication. ![]()
