Hi all,

I am trying communicate (telnet,ssh etc) between my host PC(RHEL4) and target (Pxa 255 running with linux) using USB cable.

1) I enabled the target as a USB slave, and assiged an ip.
2) The result of ifconfig in target

3) Then i connected the USB cable between host and target.
4) Then i assigned an ip to usb device in host.
5) The result of ifconfig in host

Now i tried to ping the target using
ping 192.168.1.63
but it is says host is unreachable. But if connect the LAN cable, i am able to ping to both 192.168.1.50 and 192.168.1.63 of target.

Please guide me what is the way to proceed?

You don't say what sort of USB cable you are using.

Why are you trying to use USB when you have Ethernet?

Its working for me now.... I am using USB host to slave cable.
I was unable to ping because i was using different gateway for host and target.

Thanks for the reply
