我是 Ubuntu 新手。我有一块用于嵌入式开发的 Ubuntu 运行板。我正在尝试配置华为 EC315 调制解调器以实现网络连接。
输出lsusb如下：
root@texe_hub:~# lsusb
lsusb: cannot open "/usr/share/usb.ids", No such file or directoryBus 002 Device 001: ID 1d6b:0002
Bus 001 Device 002: ID 12d1:14db
Bus 001 Device 001: ID 1d6b:0002
我可以使用以下命令成功将设备从大容量存储切换到调制解调器：
root@texe_hub:/etc/udev/rules.d# usb_modeswitch -v 12d1 -p 1f01 -J
Look for default devices ...
product ID matched
Found devices in default mode (1)
Access device 003 on bus 001
Current configuration number is 1
Use interface number 0
Use endpoints 0x01 (out) and 0x81 (in)
USB description data (for identification)
Manufacturer: Huawei Technologies
Product: HUAWEI Mobile
Serial No.: not provided
Using standard Huawei switching message
Looking for active driver ...
OK, driver detached
Set up interface 0
Use endpoint 0x01 for message sending ...
Trying to send message 1 to endpoint 0x01 ...
OK, message successfully sent
Reset response endpoint 0x81
Reset message endpoint 0x01
-> 运行 lsusb 来记录任何变化。再见！
此后，当我尝试使用加载驱动程序时modprobe，出现以下错误。
root@texe_hub:~# modprobe usbserial vendor=0x12d1 product=0x14db

如何修复此问题？请指导我该怎么做才能使其正常工作。
