I've never seen my provider exceed 2Mbps, a few hunderd kpbs is more common, so for me ppp is enough. I forgot to mention that even though the lsusb output i provided identified the device as an E398, the print on the bottom of the stick says "E352 HSPA+ Modem". > I just posted my first draft of a working CDC ECM based driver with QMI > support.

I really know next to nothing about USB nor HSPA/LTE nor CDC/NCM. I'm able to and willing to test provided drivers and patches, I can even do some trivial patches like adding usbids/interfaces, but "try combining the QMI support from it with the cdc_ncm" is way out of my league, sorry. -- Alex Hermann -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
