Not that one, but I've been playing with a mdm9200 based modem lately, which unless I'm mistaken provides pretty mush the same functionality for the european frequency bands. Ref: https://developer.qualcomm.com/develop/mobile-technologies/3g4g-connectivity-gobi The modem is probably already supported using one of the serial interfaces provided by the "option" driver, using traditional AT commands and ppp. But my testing has shown that you cannot push more than 8 Mbps upstream using ppp, most likely due to processing load in the modem itself. Because of the obvious limitations of ppp, I started making a driver for the ethernet emulation these chips support. This involves exposing the Qualcomm MSM Interface (QMI) protocol to userspace, so a userspace app (like ModemManager) can configure the device. Most of the kernel support will be in Linux 3.4. No ETA on the userspace support unfortunately. But I do have some primitive scripts which can be used to demo the driver. Let me know if you are interested and have the capability for testing this driver, and I'll try to provided more details. The driver discussions are also openly available on the linux-usb and netdev lists, and the driver itsef in in linux-next. Look for "Huawei E398/E392", "cdc-wdm" and "qmi_wwan". You don't happen to have a "lsusb -v" dump for the device, do you?
