Subject: Re: [PATCH] plusb.c patched to support Belkin F5U258 USB host-to-host cable

Hello,

Sorry to hijack this thread, but today I bought one host-to-host USB
cable, and it's a Belkin F5U258.

I applied it against my linux 2.6.26 tree, enabled plugged the two
ends into two ports of my computer, used "ip l set usb0 up" and "ip l
set usb1 up", started an "arping -I usb0 <some address>" and "tcpdump
-i usb1", and I see packets.
Then I changed the mac address of usb1, let ipv6 choose a link-local
address and pinged it from usb0, it's working too.
I didn't try some more advanced test as I only have one computer at
the moment (but it should be possible to do something with iptables, I
did it once)

The attached file is the dmesg output, I see timeouts when the
interface is set to up (at 895 and 985), but nothing else, is this ok?
