You get an "Input/output" error when trying to connect to a USB CDC-ACM device. These devices include, USB modems, mobile phones, and any USB device that uses Heyes modem "AT" style commands.
The `minicom` command will give this error:
minicom: cannot open /dev/ttyACM0: Input/output error
The `screen` command will give this error:
Cannot open line '/dev/ttyACM0' for R/W: Input/output error Sorry, could not find a PTY [screen is terminating]
The `kmobiletools` command will just fail to connect to your mobile phone without a unique error.
The problem is with your USB hub or host adapter.
Unplug the device and plug it into a different hub or USB port on your system. That will usually fix the problem. If you only have a few ports and no hub then it means your host adapter is confused. The only solution I have found is to reboot.
