    Hi,

       I am trying to set up a DSL router based on FreeBSD and in the process I
    need to make a PPPoE connection to the DSL modem using a USB network inter-
    face. The make/model is "Teledat Fast Ethernet USB". It is recognized by
    FreeBSD as "aue0".

    With FreeBSD 4.6-RELEASE, I had the following problem:
    * The card worked fine when plugged in after boot and "found" by usbd,
      but on system shutdown or when disconnecting the card from USB, I
      got a lot of "usb error o rx: IOERROR" and the system hung. When
      booting with the card already connected, it would be detected and
      visible with "ifconfig" but at the first attempt of accessing it
      using "ppp", I got into an endless loop of "aue0: MII read timed out".

    With FreeBSD 5.2-RC1, the card behaves more consistently:
    * No matter whether you boot with the card attached or not, the first
      attempt of accessing it using "ppp" will always cause an endless loop
      of "aue0: MII read timed out".

    I found a message by Scott Mitchell on this list from last October
    (http://lists.freebsd.org/pipermail/freebsd-questions/2003-October/021984.html)
    in which he suggests that a 100 Mbps network might give the driver trouble.
    I am on a 100 Mbps network (since I put a little 10/100 switch in between
    the 10 MBit DSL modem and the USB NIC), but forcing the aue0 interface to
    10 MBit via "ifconfig aue0 media 10baseT/UTP" did nothing to solve
    the problem.

    Any insights are most appreciated!

    Bye
    Frederik
