Hi, I'm back with the results. And to make it short, everything works now. Thank you, Hans and Pyun, and all others who looked into this for me.

OK, the patch usb2_ethernet.patch2 in <20090212043033.GC6313@michelle.cdnetworks.co.kr> worked, and now the ue0/AXE interface is working fine. Though I have only tested in 100BaseTX/full-duplex mode, ping -f over a 100Mbps switch run without any packet loss (sysctl net.inet.icmp.icmplim=0, of course), and the interface statics shows no errors too: Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll ue0 1500 <Link#4> 00:90:cc:xx:xx:xx 32634 0 32192 0 0 ue0 1500 192.168.1.0 192.168.1.3 32553 - 32190 - - Also, At Thu, 12 Feb 2009 12:51:00 +0900, Hiroharu Tamaru wrote: > I also have em0/em1 interfaces, and I am switching with ue0 > when I test AXE. > > It turned out that although I 'ifconfig em0 inet delete > down' those unused interfaces, the arp table entries remain. > 'arp -nda' shows 'delete: cannot locate 192.168.1.1' and the > like for every entry in the table, and they are infact not > deleted. Deletion fails both when em0 is up and down. This symptom was solved after I have brought my userland in sync with the kernel. So here I am, with all my USB2 problems solved! Thank you all for this quick assistance! And finally, I'd appreciate if you could send me or the list the 'commit done' message on this ethernet patch and the mountroot delay patch, so that I can mark to forget about patching the kernel as I cvsup it. Thanks. Hiroharu
