I am using Delphi ESR 2.5 (it's a radar) and has two ways to communicate (CAN and Ethernet), first I did it using CAN and is working.

The second one which I thought it would be easier is the Ethernet. I got an USB-Ethernet adapter from the internet (cheap one) and tried to ping using the following link:

But didn't work, Radar ip is 192.168.1.22 and pc 192.168.1.21 connecting them directly (without gateway and subnet mask 255.255.255.0)

So today tried with another USB-Ethernet adapter and didn't work too.

Should I try with the one specified in the manual (Monoprice USB 2.0 adapter)?

Or model/brand are not important and I have another problem which I couldn't figure it out?

I tried to communicate with the radar by two different ways:

1) ping 192.168.1.22

2) roslaunch delphi_esr delphi_esr_eth.launch after setting ip address in the launch file

From your description I wouldn't know what the actual cause would be, but I would assume that "no", the brand doesn't matter, as long as the NIC is of sufficient quality (ie: doesn't lose connection every N seconds, is capable of sustaining the required transfer rates, etc).

Note that -- in general -- USB devices will not be as performant as their PCI(E) counterparts.
