USB ethernet adapter connected and found in ifconfig, but not working
I've bought a USB ethernet adapter for my ARM-Board running debian to have a second interface. I compiled and loaded the driver/module and the device is being recognized:
[ 5.285487] usb 2-1.3.1: new high speed USB device number 5 using usb20_host

Then I ran
ifconfig eth1 up
ifconfig eth1 192.168.2.2 netmask 255.255.255.0
then showing up as:
ifconfig eth1
eth1 Link encap:Ethernet HWaddr 80:4a:56:02:1e:84
inet addr:192.168.2.2 Bcast:192.168.2.255 Mask:255.255.255.0

But when connected to the ARM-Board the LED on the device (for link and activity) do never show up. Therefore I checked the power consumption (despite the fact that the USB ethernet adapter is connected via an active USB hub):
lsusb -s 002:005 -v | grep MaxPower
MaxPower 248mA
Furthermore, I can't ping the IP form outside, nor I can reach any other PC or gateway in the network. So it seems that I/O isn't working at all. Fully working and also blinking is the adapter when connected to my laptop running opensuse 13.1 (with included drivers). Any ideas what could cause this problem?
EDIT2: In the current setup both interfaces are connected to the same switch, I also interchanged the cables and tried in total 5 different ones, all them are working when using the usb adapter with the laptop connecting to the same switch:

You should make sure that the routing table and the DNS are correctly configured. To fix the first:
sudo ip route add 192.168.2.0/24 dev eth1
sudo ip route add default via 192.168.2.1
and for the second, as sudo, add the folloing two lines to /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
