Hi, Donald.
 
Try this command below (instead "dmesg | tail -100"):
cat /var/log/dmesg | tail -100
And you typed "/sbin/ifconfig-a", but the command is "/sbin/ifconfig -a". Need 
to put a space between the command "/sbin/ifconfig" and the option "-a".
Try again and show us the results.
 
Also, try this command "/sbin/mii-tool", before and after inserting the USB 
device.

Senhor! Naquele tempo, disse Jesus aos seus discípulos: 7“Pedi e vos será dado! 
Procurai e achareis! Batei e a porta vos será aberta! 8Pois todo aquele que 
pede recebe; quem procura encontra; e a quem bate a porta será aberta. 9Quem de 
vós dá ao filho uma pedra, quando ele pede um pão? 10Ou lhe dá uma cobra, 
quando ele pede um peixe? 11Ora, se vós, que sois maus, sabeis dar coisas boas 
a vossos filhos, quanto mais vosso Pai que está nos céus dará coisas boas aos 
que lhe pedirem! 12Tudo quanto quereis que os outros vos façam, fazei também a 
eles. Nisto consiste a Lei e os Profetas”. - Palavra da Salvação. - Glória a 
vós, Senhor.

Assunto: Re: [LINUX_Newbies] Re: Installaling a second Network connector
 

 
   
 
Thank you Cameron but no cheers!   Using the command /sbin/ifconfig-a on the 
first Terminal did produce the eth0 and lo and also wlan0.  When I type in the 
dmesg |tail-100 ....I get bash command not found!    So maybe I am not typing 
this command correctly.
I opened a second Terminal plug in an adapter, wait several minutes type dmesg 
| tail-100 ...I get again command not found.   I then type /sbin/ifconfig-a 
...this time I get the following 
bash: /sbin/ifconfig-a: No such file or directory.    I am at the root level 
when I am giving these commands. 
It really seems that Centos does not see the adapter.
Thank you for you help.  If you have any more suggestions, I would certainly 
try them out.
Thank you
Don

My instructions were for the command line.

Please open a terminal.
At the command prompt, type:

/sbin/ifconfig -a

Note what inferaces are shown; probably "lo" and "eth0".

Type the command:

dmesg | tail -100

Leave it on the screen for reference.

Open a second terminal.

Plug in a USB adapter and wait a few seconds.

Type the command:

dmesg | tail -100

Is there new stuff at the bottom of the output?

Type the command:

/sbin/ifconfig -a

Are there any new ethernet interfaces shown?

Repeat with each USB adapter until one or both of dmesg and ifconfig show new
stuff (ideally both).

When ifconfig shown a new interface you can try to configure it with
whatever setup tools your desktop interface offers.

Anyway, please try the command line based experiments recited above and
report.

Cheers,
