Hi,
the problem is in usb-modeswitch.sce
I have converted and make the fusion of usb-modeswich.tcz and usb-modeswitch-data.tcz from the Core5.x repository to an usb-modeswitch5.sce and an usb-modeswitch5.sce.dep with:
usb-serial-3.16.6-tinycore
usbutils
wvdial
tk
Then the sce-import of usb-serial-3.16.6-tinycore, usbutils, wvdial and tk
then sce-load usb-modeswitch5.sce
plug the dongle, and the results of dmesg:

and... Got it!
Of course this is not a very polite system to make or import an .sce but it says that the problem is in usb-modeswitch.sce from the ubuntu repository and that perhaps it is necessary adding some dependencies like tk (tcl and tk in Core5.x) and others that perhaps are not in the original .sce and probably in dCore-jessie too. That is the next prove.
At least, perhaps, it can be make a script to create this usb-modeswitch.
