One has to remember that USB is just the bus just like pci,=0D=0A micro=
channel, etc. Even though you have access to the device on the=0D=0A bus=
you still need a driver for that specific ethernet chip your=0D=0A kern=
el. This is analogous to having a video card on the pci bus, you=0D=0A s=

regardless if it can see it on the bus.=0D=0A I have an HTC Nexus One s=
o I may fiddle with this and see if I can=0D=0A help some more here. I a=
m wishful that at least we can get a tty=0D=0Ajust=0D=0A like other gsm =
modems and from there it's pretty straight forward=0D=0A using wvdial or=
alike. If it's only the Ethernet over usb like you=0D=0A mention, then =
the chipset driver would have to be translated/ported=0D=0A to=0D=0A the=
FBSD kernel, if it's not already there ?=0D=0A Ok. But I will clarify he=
re:=0D=0A The HTC Android systems uses an "Internet Sharing" feature-=0D=0A=
essentially Google has coded in routing/nat system into the base OS=0D=0A=
(probably moding the leftover code already in the linux base), and is=0D=
=0A trying to allow similar using bluetooth and wifi at a later date as=0D=
=0A well. The RNDIS is a M$ system that allows sharing anything over USB=0D=
=0A (network, files, etc- but all essentially operated as network=0D=0Aan=
yway),=0D=0A something they've been playing with for some years- I was lo=
oking for=0D=0A an A-A USB cable since around 2003 or so to quickly trans=
fer files=0D=0A when needed. Apparently M$ opened the specs a year or two=
ago and=0D=0A everyone's jumped on to use it. So where Google started wa=
s to start=0D=0A allowing the use of the router/nat via RNDIS USB - someh=
ow this was=0D=0A easier than allowing bluetooth or wifi (probably securi=
ty and=0D=0A available hardware features).=0D=0A So yes, apparently the p=
hone hooks up as a usb mass storage device,=0D=0A uploads a file to the c=
