simcom7100c在ubuntu下移动宽带mobile broadband上网

自己的ubuntu版本是14.04lts 已经包含了qmi的qmi_wwan.ko驱动

首先装载驱动Insmod (modprobe) cdc_wdm

然后装载 insmod (modprobe) qmi_wwan
下一步将vid pid写到new_id里面echo "vid pid" >/sys/bus/usb/drivers/qmi_wwan/new_id

sudo echo "1e0e 9001" > /sys/bus/usb/drivers/qmi_wwan/new_id

chit@ubuntu:~$ sudo find / -name qmi_wwan* -print
