Sorry, I don't have any other suggestion than using the modems/firmwares you have found to be working.

This is a dongle ( Huawei E3131-s2 ?) with both ncm direct ethernet interface and serial ppp interface, don't load the cdc_ncm driver if you use it in serial ppp mode. I've seen the same callback error and dongle firmware crash in the past when both protocols are active. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

USB-modem not working correctly
Hi list, I'm trying to get an USB-modem running on a Smileplug, which is some Arm7-device, using it with the kernel 3.12-6. As far as I can tell it's an USB3-port.
