Huawei K 4203 USB modem support ?

[murat göttendelik]

Hi,

I have a K4203 USB modem. I tried to use it as a 3G backup on 2nd WAN, but it is not supported by the router.
Would it be possible to add support for this modem ?

Thanks.

Q: I'm having problems with my 3G/4G USB modem. Can you help/can you fix it/can you support it?
A: I don't touch the USB modem support code since I have no way of testing anything related to that feature.

thanks for your response. what can I do about this ?
is there a way for me to add a linux module to the kernel ?

Hi,

I've found some information on the page below and the following command changed mode of the USB.
Now the K4203 is working with my AC88U

usb_modeswitch -v 12d1 -p 1f1c -W -I -M 55534243123456780000000000000011062000000101000100000000000000

Now, how can I make this persistent ?
Should I put it in a script ? if that's the only way, on which script should I put this command ?

no. that's not actually correct.
when I do that modeswitch command, the USB modem is identified as an ethernet port and Asus router can not handle the PPP connection over it.

So, I need some other solution.
Maybe a module to support it as a USB 3G modem.
