Have you tried using the full pathname? Just type the following on the
command line.
/opt/Eltima/eveusb/bin/eveusbc

Hi Peter,
Thanks so much for you help.
Here is what I'm getting with permissions. It looks like it has
execute permissions?
root@beaglebone:~/usr# dir
bin share src
root@beaglebone:~/usr# cd bin
root@beaglebone:~/usr/bin# dir
eveusbc eveusbd
root@beaglebone:~/usr/bin# ls -l
total 0
lrwxrwxrwx 1 root root 30 Dec 5 2014 eveusbc ->
/opt/Eltima/eveusb/bin/eveusbc
lrwxrwxrwx 1 root root 30 Dec 5 2014 eveusbd ->
/opt/Eltima/eveusb/bin/eveusbd
root@beaglebone:~/usr/bin# .eveusbc
-bash: .eveusbc: command not found
root@beaglebone:~/usr/bin# chmod 777 eveusbc

Hi Ian,
Thanks for your email. Yes, it works more or less like in DOS, but
there are some differences:
- most Linux systems are configured such that root (as opposed to
most other users) does not by default execute files in the current
directory. This is for security reasons if I'm not mistaken. This
can be bypassed by typing the relative or full path to the
command, such as ./eveusbc . Since that doesn't work, it is worth
looking into another important difference with DOS:
- Linux systems have more extensive file permissions than the
original DOS system. It could be that the eveusbc file does not
have "execute" permission. You can check by 'ls -l', which shows
the permissions in a format such as rwxrw-r--. There are three
groups, identifying permissions for owner, group and world (from
left to right). Each group can have r(ead), w(rite) and execute
permissions. To excluse any problems in this area, you can give
all permissions to everybody by 'chmod 777 eveusbc' and then try
again './eveusbc' .
By the way, 'chmod 777' is not necessarily the best way to keep a
computer secure ;-) but it should help determine whether the
problem is related to permissions.

Hi Peter,
Yes I'm logged on as root but I'm in the directory where the
file is.
Does this not work the same as DOS?
I tried typing ./eveusbc but I just get "No such fie or directory"
I must say I'm lost.
Any ideas?
Thanks
Ian

Try ./eveusbc
From the prompt it seems you are logged in as root and
usually root does not have the current directory in it's
path for executing commands.
Best regards,
Peter
