I'm using my IBM Lenovo T60 for work only purposes. And I've chose to install Linux Mint Daryana on it. For a couple of days ago I upgraded to Elyssa and after a while I found out that I had problems using my COM port. I always have used USB - RS232 converter, but now it doesn't work. Also, my com port on my DOCKING- station also fails to work ( without the usb to rs232 converter ).
The error message I get from my terminal emulator is:
Minicom: Device disappeared, aborting!
I can also see that the USB to rs232 converter is disappearing from the lsusb output.
And the COM port on my docking station also disappear from the lspci output.
PS. Tried the same on my colleague's laptop too.. Worked with Daryana, not with Elyssa.
Can someone help me to get the COM port up and running again? =)
Here's an output from dmesg:
