Reviving a thread from June,2015...
My brand-spanking new XPS 13 has a dongle for the Thunderbolt port that
implements a RTL8153, which
is recognized by my system (FreeBSD 11.0-RELEASE-p1 #8: Tue Oct 18 22:57:49 PDT
2016):
Oct 19 07:11:01 TWE6 kernel: ugen1.3: <BILLBOARD CLASS> at usbus1
Oct 19 07:11:02 TWE6 kernel: ugen1.4: <GenesysLogic2> at usbus1
Oct 19 07:11:02 TWE6 kernel: uhub3: <GenesysLogic2> on usbus1
Oct 19 07:11:02 TWE6 kernel: uhub3: 4 ports with 3 removable, self powered
Oct 19 07:11:03 TWE6 kernel: ugen1.5: <Realtek> at usbus1
Oct 19 07:11:03 TWE6 kernel: cdce0: <CDC Communications Control> on usbus1
Oct 19 07:11:03 TWE6 kernel: ue0: <USB Ethernet> on cdce0
Oct 19 07:11:03 TWE6 kernel: ue0: Ethernet address: 00:24:9b:1d:90:e5
NB: the MAC address matches that inscribed on the dongle.
usbconfig info:
ugen1.5: <USB 101001000 LAN Realtek> at usbus1, cfg=1 md=HOST spd=SUPER
(5.0Gbps) pwr=ON (64mA)
NB: cfg=1 which should be correct for if_cdce and RTL8153. This was verified by
'usbconfig -d 1.5 dump_curr_config_desc" (complete configs dumped below).
I manually set the IP address:
ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 00:24:9b:1d:90:e5
inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
The problem is, "it doesn't work'.
Using wireshark on a ping target machine, I can see that the XPS outputs
packets (which look correct), but it
doesn't seem to be receiving the replies. When I set 'sysctl -a
hw.usb.cdce.debug=1' I get a constant (~ 5Hz) stream
of "cdce_intr_read_callback: Received 24 bytes" whether there is network
traffic or not; when I ping the XPS
this message doesn't change.
The hardware/cable works OK under Windows.
Any guidance is appreciated; TIA
David
