for tethering you shouln't need a package at all: on phone side you should
be able setup USB debugging mode (permanently) and enable tethering after
the phone has been connected to the Linux machine.
Having D7/XFCE and a Samsung Galaxy S2 (SGS2) I thought I'd try this,
but without success, so far.
Expected behaviour:
- Plug in SGS2 to laptop USB port, set USB tethering
- See a new interface listed in wicd
- Be able to choose to connect, disconnect, set IP settings, DNS, etc
Actual behaviour:
- Plug in SGS2 to laptop USB port, set USB tethering:
Done
- See a new interface listed in wicd:
SGS2 or usb connection not listed
- Be able to choose to connect, disconnect, set IP settings, DNS, etc:
Unable
Not much of an expert on network drivers etc in Linux, so would
welcome some guidance on exactly where to look for the problem, but
here are the relevant syslog entries. The first block is when
plugging in the SGS2, before the USB tethering was selected. The
second block is the Debian response once the SGS2 was in tethering
mode. [The syslog extracts have had date, time, and machine name
removed to make the lines shorter, and easier to post and read.]

Notes:
(a) The udevd line is very long, so I've added a blank line above and
below it for readability on the list in cases where the reader will
wrap the text
(b) wicd does not list this usb interface, listing only its existing
wired ethernet adaptor, and the different wifi networks that its
built-in wifi device can receive.
Does the syslog extract show it working, or not? Perhaps there is
another log that would be useful - I checked dmesg but that contained
nothing since startup. /etc/network/interfaces only contained eth0
(the wired socket on the laptop). Should wicd be able to list the
SGS2/usb device or connection?
Not knowing much about the networking setup in the machine, I really
Would be very grateful for any suggestions; it would be worth getting
it to work.
