[sane-devel] Troubles with PIXMA MX870 and USB

I got some more info on the router issue and ADF Duplex. ADF Duplex
works properly - I just had to set the page count properly or tell the
client to scan all available pages (e.g. in gscan2pdf). I hadn't tried
very hard at the time of writing and figured it out later this afternoon
- sorry for that.
Second info is on the router. Although it was supposed to handle the DNS
lookup of local ip addresses, it seems it doesn't handle it at all. The
wrong DNS entries seem to come from my ISP (Vodafone in Germany). I
"solved" the issue by configuring an external DNS server in my router
(i.e. the resolv.conf on my computer still is configured to use the
router as nameserver, but the router acting as DNS proxy gets
information from an independent DNS server - not the one provided by my
So, for now the USB connection (not working at all) is the worst issue
(would be faster then wireless networking, I hope ;-)).
