Debian Jessie无法使用usb调制解调器热插拔

当我在电脑启动前连接调制解调器时，一切正常。但当连接到工作PC时，会出现错误

没有使用任何来自其他地方的驱动程序，所有的工作都是在默认的debian jessie存储库上进行的

这里是dmesg：

已发现：

按照正确的顺序，

cdc_ether

首先加载，并对 装置。新的

eth1

界面已配置，一切正常。之后 做了一些研究后，我决定试一试。如果我们只是 禁用了sierra驱动程序？这似乎是最新的Sierra Wireless 这个设备其实并不需要那个驱动程序，因为它可以通过USB进行通信 疾病控制中心。它会伤害什么？没什么，我想，所以我敞开了心扉

/etc/modeprobe.d/blacklist.conf

（别忘了用

sudo

调用

vi

） 然后去上班。下面是我在底部添加的内容
