Sierra MC7354

[szlin]

Hi,

Module name:          Sierra MC7354
Vendor/Product ID:  0x1199/ 0x68c0
LIBQMI version:      1.8
Linux version:          3.12

I got the following error message *in sometimes*, after seeing that ,
system will be crashed.

#qmi-network /dev/cdc-wdm0 start

Does anyone connect to Internet by using MC7354 via libqmi library ?

Thanks for any advice.
