My MC7710 can't work on Linux after plug-in it to Windows8

IoT Modules MC/EM Series
12

If you are really brave, then you could try a perl script I hacked together based on the MBIM and QMI code I used while developing the drivers:
git.mork.no/?p=wwan.git;a=blob_p … usbcomp.pl

I have tested it on an MC7710 and an EM7305 and it seems to do the job for me. I tried configuring the EM7305 for MBIM only (although it still showed the DM channel):

And then I ran the script with a “–usbcomp=19” parameter:

./swi_setusbcomp.pl --device=/dev/cdc-wdm2 --usbcomp=19

which provided the current setting before changing it to 19:

bjorn@nemi:~/privat/prog/git/wwan/scripts$ ./swi_setusbcomp.pl --device=/dev/cdc-wdm2 --usbcomp=19

After resetting the modem (which the script will not do), I got a multi config device as expected:

Let me know if you try this. Note that the descriptions are hard coded in the script, based on the AT command output from the MC7710. I don’t know how to dynamically retrieves these. This will probably not work as expected on newer modules (MC7455 etc). But it should be easy to adapt to those if anyone is willing to debug a bit.
