Re: [gentoo-user] tethering an htc incredible

[Allan Gottlieb <gottlieb@nyu.edu>]

I should first add that I have verizon and that I have not contacted
them.  I am willing to contact them and pay a monthly fee if necessary
for the times I am away from normal wifi access (basically two weeks
on a NH island).

I should also add that in all my attempts I have never had
ifconfig report a usb0 entry (or any usbN) and have never had
a /dev/usb0 (or usbN).

Thank you all for your help.

I do not see a "tethering" option.  I do see "3G mobile hotspot" and "3G
modbile hotspot settings".  These seem to relate to having the phone act
as a wireless access point.  This requires contacting verizon, but does
not seem to be the option in question since it is for wireless access
not usb access.

I do see mobile broadband connect.  When I select it, it does show
that the USB connection has been changed to mobile broadband connect.
But nothing extra appears in dmesg.  I have previously set this option
permanently on the phone for testing (rather than changing to it after
plugging in the usb cable) also with no success.  This is the reason I
feel that I must have some kernel option missing.  I do have the ones
suggested in a forum post (now they are built in, I also tried as
modules).

CONFIG_USB_NET_CDCETHER=y
CONFIG_USB_NET_CDC_EEM=y
CONFIG_USB_ARMLINUX=y
CONFIG_USB_ACM=y
CONFIG_USB_WDM=y

There are no changes to dmesg output after I enable mobile connect

When I plug in the phone dmesg gives
