Huawei GP02 (E587 mobile router, japanese variant)

Post by CawCaw » 17 Dec 2012, 14:08

Hello, I just wanted to post a working config (sniffed on WinXP). Please add this to data package. Thank you.

Huawei GP02 (E587 mobile router, japanese variant)

Works fine with patched cdc_ncm driver. Thanks Tommy, Bjørn and Olof!

Thanks a lot !

This will go into the next data package release, of course.

There is an "official" mode switching command for Huawei devices and Linux. Could you try it once for the sake of device documentation? Afterwards, an output of "lsusb -v"would be most welcome.

This is 'the other' command:

Thank you for your advice. I misunderstood how to find the message.
I did it again with the 'standard' MessageContent (recommended by Huawei).

sudo usb_modeswitch -v 0x12d1 -p 0x1c1b -M "55534243123456780000000000000a11062000000000000100000000000000"

..and I got same result!

..and I got same result!
That is not the std Huawei message, compare again with the msg Josh posted.
You have that single "1" in a different position and its position is important!

You also got an "a" before 11062 which isn't part of a std message.

Thanks for checking, no problem with "smilies" ...

So there seems to be only one mode for this router, and it has "Huawei NCM devices disguised as vendor specific" (quote from Bjørn's patch).

Interesting.

Thanks again, CawCaw. If you want you can give me your name (or any nickname of your choice) via PM or mail, and I'll include you as the contributor of this device in the reference file.

Re: Huawei GP02 (E587 mobile router, japanese variant)

Hi

I am trying to connect the E587 to an Openwrt router for sharing over a network as the speed is far superior to ADSL lines where I live

So the target router is TL-3420 with Openwrt flashed Luci web interface etc... followed the setup at https://forum.openwrt.org/viewtopic.php?id=41069 no problems

I am using the manufacturer recommended modeswitch "55534243000000000000000000000011060000000100000000000000000000"

What I get is a router reboot as soon as the automatic modeswitch happens (seconds after plugging in the modem). the output of dmesg and logread just before the reset are as follows:

dmesg

Could this be a sudden power drain on the router or some other problem with the modeswitch?

Has anyone seen anything similar?

Try with a separately powered usb hub in between to see if it is a power drop issue.

TP-Link routers do often have "weak" power on the usb port, I have a MR-3420v1 which can handle some 3G modems but not others.
In your case I think it may be the charging circuit for the battery in the E587 that switches in and makes the power drop so much that the router itself doesn't get enough power.

Thanks for your reply

That helps me a lot, as at one time I was working well with it without resets and I couldnt work out what had changed but it was most likely a partial battery discharge that has upset the whole issue, I will try a powered usb hub and see how it goes.

at first I thought it was some parameter in the usbswitch message.

No, your dmesg shows that the modeswitch was successful and the ncm drivers gets loaded after the device reappears in target mode.

Hi

Still have the same problem even with a powered usb hub, it still seem to be when the usbswitch happens or very close to this , I cannot tell as the tplink unit locks up as soon as it happens

The new dmesg is

I can't see any problem from your logs, whatever makes the router reboot is lost from being logged, usb_modeswitch has done what it should do and has exited after loading the option driver.

Comment out the bridging of the wwan0 device in the luci gui so that the device is not used and check if the router still reboots.
Do you use the latest 3.7.5 from trunk with the updated ncm driver?
You are probably better helped by posting your problem in the openwrt thread you linked to, the users there has a better knowledge about the builds and their configurations.
