Knowing the chipset and device ID might provide some clues. Post the output of the lsusb command.

I have connected my USB ethernet and ran the command lsusb i get this..

Code:

[root@localhost ~]# lsusb
Bus 001 Device 001: ID 0000:0000 
Bus 001 Device 002: ID 148f:2573 Ralink Technology, Corp. RT2501USB Wireless Adapter
Bus 002 Device 001: ID 0000:0000 
[root@localhost ~]#

Is there anything else i need to do ?

When i insert the USB ethernet in USB port and connect a LAN wire from switch to it. There i get a red light on the USB ethernet.

Is there no auto plug and detect utility ?


Running ifconfig show the below....

Code:

[root@dhcppc1 ~]# ifconfig

when you uselinux there no need to install drivers to support linux automatially catch drivers..you can use
ifconfig... then you 'ld check your status id.
you should check your eth0 setting & change this for active state
