Serial Connection problems

[JDMoore0883]

Hello everyone!

So this seems to me to be a bit more of an OS issue on my end, but I will post for help nonetheless... So I am using a USB Serial connection to the Pi. In windows, using PuTTY, the connection is fine. When I try to use it in Linux however, it doesn't. Here is the command I am using:

sudo minicom -b 115200 -D /dev/ttyUSB0

I get prompted for my sudo password and minicom comes up. But the bottom right status lists as offline, and there is no responses to any input. If I unplug the USB cable, I get an error about not being to read the /dev/ttyUSB0 device.

I am very sure I am doing something wrong somewhere, as the connection is fine in Windows and PuTTY, but I can't for the life of me figure out what and where things are going wrong.

Any ideas?

I've also had issues with getting minicom to work and, eventually, both on my Pi's and Ubuntu netbook found GtkTerm easier to set up and get working (from the Desktop)

Not sure if this will help but I only use sudo with minicom when setting the config. After that don't use sudo.
