Hi I get a LED light on the Tobi expansion board near the USB connector

This is the output of the command
tail -f /var/log/syslog
Jan 14 20:02:02 ubuntu kernel: [178209.569697] usb 2-1.2: device descriptor read/64, error -32

It appears as though it has problems recognizing Tobi. What should i do?

If you watch log on your workstation do you'll see which serial port to use.

For example on Ubuntu when plugging in the Tobi board console connection

scott@hex:~$ tail -f /var/log/syslog
Jan 14 09:02:38 hex kernel: [11985.448132] usb 4-2: new full-speed USB

Make sure you belong to the appropriate group to open the device. It's
'dialout' on Ubuntu.

scott@hex:~$ ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Jan 14 09:02 /dev/ttyUSB0
scott@hex:~$ grep dialout /etc/group
dialout:x:20:scott


For kermit a ~/.mykermrc  file like this might be useful.
Change the set line device as appropriate.

scott@hex:~$ cat ~/.mykermrc
set line /dev/ttyUSB0
set flow-control none
set carrier-watch off
set parity none
set stop-bits 1
set speed 115200
connect

Then you can just type kermit at the prompt.
