next in thread | raw e-mail | index | archive | help
I have a HP Pre3 (webos) which when switched into USB tethering mode with
freetether exposes a RNDIS Ethernet Device. This should simply appear as ue0
and off to the races. Unfortunately it attached via umodem due to the
usb.conf/devd usb_autoconf scripts and a device class overlap with if_urndis.
After commenting out those manual attach lines for umodem and kldload
if_urndis the device still didn't attach. After going into if_rndis.c and
enabling the "umodem" conflict section on line ifrndis.c:173 (I'm running
10.1) and recompling the kernel module the device appears and
functions, I'm using it to post this.
How to I make this permenant (create a quirk?) so I don't have to hack
usb.conf and if_rndis.c each time I upgrade?
Thanks,
