first: it's an issue rather for support.
second: it has been reported already (should even be mentioned under  
"known issues") and there have been several proposals for a workaround:
- add echo "nameserver XXX.XXX.XXX.XXX" > /etc/resolv.conf to your  
/etc/network/interfaces usb0 stanza
- remove the link and create a file /etc/resolve.conf
