Hello,

I'm making an attempt to migrate my laptop strictly to linux. However, I have a USB to serial adapter "FTDIBUS\COMPORT&VID_0403&PID_6001" which I regularly use to console into various hardware routers, switches and ect. I've attempted several online guide with no luck. Any help getting this to work would be greatly appreciated.

Linux Mint 14 64-bit

Thanks in advance!

sudo lsusb yields the following:

Bus 003 Device 009: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

I tried:

sudo mknod /dev/ttyUSB0 c 188 0
sudo mknod /dev/ttyUSB1 c 188 1
sudo mknod /dev/ttyUSB2 c 188 2
sudo mknod /dev/ttyUSB3 c 188 3

Then tried connecting putty to /dev/ttyUSB0 as well as /dev/usb/ttyUSB0 with no avail. Also,

dmesg | grep tty

Solved. Below is total work performed to resolve issue.

1. Physically connect USB-Serial Device
2. Verified adpater via "sudo lsusb"
3. Used sudo mknod /dev/ttyusb0 c 188 0
4. Added user to dialout security group
5. Configured putty to run with higher privileges. I did this because "sudo screen /dev/ttyUSB0" would let me connect to my switch via the console port, but putty would not work until I elevated it's privileges.
