Description of problem:
Using a serial port connected via USB, setserial fails with the message
"Cannot get serial info: Invalid argument" for all comands.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Connect a serial port to the USB bus, verify it's up&running.
2.Issue any setserial <USB-port> command.
3. Watch the error message
Actual Results: Error message as described above
Expected Results: Either functionality as described in the setserial(8)
manpage, or a decent error message saying that this kind of device isn't supported
If setserial isn't implemented for these devices, the documentation must be
overhauled. In particular, the description for how to set up
pppd relies on a working setserial.
May I look at /proc/bus/usb/devices?
No time to write the code for that feature. Bug the author...
