Hi, My daughter has a new smartphone, a Samsung S8. She want to transfer files to it, but it's not working. Plugging in the phone in her laptop and setting the phone's USB-properties to "file transfer" results in the phone being seen. Unfortunately, from there on it fails. No way to access the phone. Rather strange, on my own PC it works. Both are running Leap 42.2. I did a journlctl -f on my daughter's laptop. This is the result : jan 05 23:03:04 julie-hp2 kernel: usb 1-3: new high-speed USB device number 11 using xhci_hcd jan 05 23:03:05 julie-hp2 kernel: usb 1-3: New USB device found, idVendor=04e8, idProduct=6860 jan 05 23:03:05 julie-hp2 kernel: usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 jan 05 23:03:05 julie-hp2 kernel: usb 1-3: Product: SAMSUNG_Android jan 05 23:03:05 julie-hp2 kernel: usb 1-3: Manufacturer: SAMSUNG jan 05 23:03:05 julie-hp2 kernel: usb 1-3: SerialNumber: xxxx jan 05 23:03:05 julie-hp2 kernel: cdc_acm 1-3:1.1: ttyACM0: USB ACM device jan 05 23:03:26 julie-hp2 ModemManager[1173]: <info> Creating modem with plugin 'Generic' and '1' ports jan 05 23:03:26 julie-hp2 ModemManager[1173]: <warn> (ttyACM0) could not open serial device (2) jan 05 23:03:26 julie-hp2 ModemManager[1173]: <info> Modem for device at '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-3' successfully created jan 05 23:03:26 julie-hp2 ModemManager[1173]: <warn> Couldn't start initialization: Couldn't open ports during modem initialization: Couldn't open primary port: Could not open serial device ttyACM0: No such file or directory jan 05 23:03:26 julie-hp2 kernel: usb 1-3: USB disconnect, device number 11 jan 05 23:03:26 julie-hp2 kernel: cdc_acm 1-3:1.1: failed to set dtr/rts jan 05 23:03:26 julie-hp2 ModemManager[1173]: <warn> couldn't initialize the modem: 'Modem is unusable, cannot fully initialize' jan 05 23:03:26 julie-hp2 ModemManager[1173]: <info> (tty/ttyACM0): released by modem /sys/devices/pci0000:00/0000:00:14.0/usb1/1-3 jan 05 23:03:26 julie-hp2 kernel: usb 1-3: new high-speed USB device number 12 using xhci_hcd jan 05 23:03:26 julie-hp2 kernel: usb 1-3: New USB device found, idVendor=04e8, idProduct=6860 jan 05 23:03:26 julie-hp2 kernel: usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 jan 05 23:03:26 julie-hp2 kernel: usb 1-3: Product: SAMSUNG_Android jan 05 23:03:26 julie-hp2 kernel: usb 1-3: Manufacturer: SAMSUNG jan 05 23:03:26 julie-hp2 kernel: usb 1-3: SerialNumber: xxxx jan 05 23:03:26 julie-hp2 kernel: cdc_acm 1-3:1.1: ttyACM0: USB ACM device jan 05 23:03:45 julie-hp2 ModemManager[1173]: <info> Creating modem with plugin 'Generic' and '1' Any hints to solve this ? Googling was no help, but maybe I'm not giving the right question. I thought usb_modeswitch would to the trick, but on both laptops it's installed, and the conf-file in /etc is the same. Or should I look elsewhere ? It's a long time since I needed usb_modeswitch, I can't remember what I did when I needed it.
