TP Link MA260, Ubuntu 12.04 LTS

[achim_59]

So here's what I got using the CS-15 (a device known to work with kernels 2.6.x and onwards)

After inserting the device check /var/log/syslog:

I am beginning to suspect that the people who put the macine together for me have done something to make UMTS impossible. If that is the case, then I will get them to fix it under guarantee. But I need to be sure. Note that both MA260 and CS-15 work fine with _WinXP. I will take an old Windows machine with me this week, so that I can continue to communicate with anyone willing to give me a hand sorting this out. incidently, I also tried lsmod, though the output is a bit of a mystery to me. I'll need to do some research to figure out what it all means. Here is the output:

To quote Marvin the paranoid android of Hitch-Hiker's Guide fame: "I think you ought to know that I'm feeling very depressed."

Please show the output of the command

usb-devices

[Sandro kensan]

I can add my info:

https://lkml.org/lkml/2013/7/30/191
https://lists.ubuntu.com/archives/ke...ly/031024.html

This is a note to let you know that I have just added a patch titled

usb: option: add TP-LINK MA260

to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree

The result of the usb-devices command for CS-15 ( I think from the info so far, that I have better chances with it):

OK, I did the fdisk thing and "catting" the fstab file. Here are the results.

Firstly without any UMTS device.

I haven't examined the data in detail, but a cursory perusal suggests that there is no difference whatever.

In the meantime I have contacted the company who put the machine together (yes it's a custom job - my employer paid for it and is waiting expectantly for me to get it working). Aside: Employer != Owner of the paying project. The company who put together my machine have sent a link to their support site. I will check the support stuff out and, if it has helpful information, I'll pass on the details.

Incidentally, yesterday I used the Nokia CS-15 for my connection and today I'm using the TP-Link MA260. I'm doing this with an old dodgy WinXP machine. So both devices are working properly.

Your device is listed in the latest version:

DefaultProduct=0xf000

TargetVendor=  0x2357
TargetProduct= 0x9000

[achim_59]

In fact both devices are listed.

The usb_modeswitch command you describe is almost the same as that which I used previously, with the exception that I included a target product ID. The following is part of my earlier post:

achim@achim-W840SU-Series:~$ usb_modeswitch -v 0x2357 -p 0xf000 -P 0x9000 -M "5553424312345678000000000000061b00000002000000000 0000000000000"

I have not yet attempted to use a config file and the -c option. I will, however, if and when I figure out why the command doesn't work as expected. I could try leaving out the target product ID, but I don't know what that would achieve.

It seems a bit odd that I would need to run the usb_modeswitch command every time I insert one of these devices. In an earlier version of 12.04 there was the option to change one of the udev rules. The device (the CS-15 at the time) would then be switched over to modem mode automatically. Is there some similar change I could make to (maybe) /lib/udev/rules.d/40-usb_modeswitch.rules?

From the message above, I am assuming that there is some package missing on my machine. I will check the support site of the computer manufacturer tonight, but it will be the weekend again before I can install anything. For those following this in the hope of some answers, you'll have to be patient.
