I get these errors on my PC

cdc_ether is loaded on my PC:

root at noteboontu:/home/andy80# lsmod | grep cdc
cdc_ether               7168  0
usbnet                 20232  1 cdc_ether
usbcore               146028  6 cdc_ether,usbnet,usbhid,ehci_hcd,uhci_hcd

ah ok

ok, I'll try again

ok, here is the output:

PC 'ifconfig -a': http://pastebin.com/m2f41af61
PC 'lsmod': http://pastebin.com/m18e33f6f
PC 'dmesg': http://pastebin.com/m6b042830
PC '/etc/network/interfaces': http://pastebin.com/m146c0e63

Tablet 'ifconfig -a': http://pastebin.com/m46e90eda

I hope to have given you all the info you need to understand the
problem. Thanks for the help.
