If a Linux system isn't booting anymore after the TRACE32 USB driver files 10-lauterbach.rules was installed, then please check, whether an irritating CR character is inside this file or not.

A check can be done with command:

cat -et /etc/udev/rules.d/10-lauterbach.rules

No ^M should be displayed at all.

In the directory /dev/lauterbach/trace32 you can find a lot of links from system devices which shouldn't exists there (e.g. audio, disk, dvd, ..)

# conversion steps

# if package tofrodos isn't already installed

sudo apt-get install tofrodos

cd /etc/udev/rules.d/

# converts all CF+LF pairs to LF

sudo fromdos -d 10-lauterbach.rules
