TP Link MA260 - cannot get UMTS device to be recognised orswitched.
Once again I am confronted with problems getting a UMTS device working. This time it is a TP Link MA260. I've downloaded the DataSheet from the TP Link website, but unless you're using some flavour of Windows, it isn't very useful.
Currently I'm running Ubuntu 12.04 LTS.
The result of running lsusb:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 8087:8000 Intel Corp.
Bus 002 Device 005: ID 2357:f000
Bus 002 Device 003: ID 8087:07dc Intel Corp.
Trawling the net I saw a lot of very techincal posts mentioning this relatively new card and that including this rather tantalising piece:USB_ModeSwitch ? View topic - New device TP-Link MA260.
This and a few other technical posts suggest that the MA260 has been "added to the kernel options", though I confess I do not know exactly what that means. I assume that means the firmware has been added. It's not entirely clear which kernel versions have been blessed with this update.
I tried the man page for usb-modeswitch and attempted to give a command to switch the device over to UMTS modem. I tried the following:
This had the effect of placing me in some sort of interactive mode in which I had no idea what to do next. So I got out with Ctrl-C. There was no change whatever to lsusb.
usb_modeswitch -v 2357 -p f000 -P 9000 "5553424312345678000000000000061b000000020000000000000000000000"
I am starting to get quite desperate, because I have no private access to internet other than a mobile device. I am doing this after hours at work so I can check the results at best tomorrow. At the weekend my time is limited so I cannot spend ages on this problem.
The MA260, it's vendor ID and product ID are all missing from the list in /lib/udev/rules.d/40_usb_modeswitch.rules. The format for this stuff also seems to have changed in the past 2 years. I look at some backups from 18 months ago and it looked quite different.
I'm happy to provide further information if anyone can help. I just don't know what's needed.
