Hello! Sorry, but i'm not sure i'm writing in the right place. I own an usb GSM modem named Olivetti Olicard 145, and with my kernel version (3.7.10-gentoo) it doesn't work just pluggin it in, but loading the usbserial generic module and passing by hand product and vendor id. Taking a look on the kernel sourced I noticed that an Olicard 100 is present in usb/serial/option.c, so I added a couple of lines in the file to try my 145 with the same module, I rebuild the modules plugged the card in, the modules loaded without doing anything and it just works. I send the patch file, I hope this can help. Filippo.
