Install driver for USB-UART bridge converter on Linux Ubuntu12.04

Ubuntu下USB转串口芯片驱动程序安装，支持cp210x,pl2303等

 

Reference: Fixing the cp210x open - Unable to enable UART Error

 

When you plugin your USB-UART converter, and run "> ls /dev/tty*", if you don't see the /dev/ttyUSB0 (or similar), your Linux does not detect your USB-UART device.

 

We need to install the driver for your device.

 

Here we use Ubuntu12.04, and Updated the source to 3.2.0 version. If there is difference about version Number from your OS platform, please try to modify it into yours.

 

 

1.Download the Linux Source Code

 

Open a terminal and execute the following commands. Note that your version of Linux may differ slightly -- adjust accordingly.

$ cd ~

$ sudo apt-get install build-essential linux-source

$ cp /usr/src/linux-source-3.2.0.tar.bz2 .

$ bunzip2 linux-source-3.2.0.tar.bz2 

$ tar xf linux-source-3.2.0.tar 

$ cd ~/linux-source-3.2.0

 

 

 

2.Recompile and Reinstall the cp210x Driver

 

From within a terminal, execute:

$ cd ~/linux-source-3.2.0

$ make oldconfig

$ make prepare

$ make scripts

$ cp /usr/src/linux-headers-3.2.0-34-generic-pae/Module.symvers .

 

Here, I have the "3.2.0-29" version also, I launched the command above, but not the below:

  "cp /usr/src/linux-headers-3.2.0-29-generic-pae/Module.symvers ."

 

Recompile and Reinstall the cp210x Driver

Here, We can actually install many kinds of USB-UART converter drivers. We take cp210x as the example.

From within a terminal, execute:

 

$ make M=drivers/usb/serial

$ sudo mv /lib/modules/$(uname -r)/kernel/drivers/usb/serial/cp210x.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/cp210x.ko.old

$ sudo cp drivers/usb/serial/cp210x.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/

$ sudo modprobe -r cp210x

$ sudo modprobe cp210x

 

Reboot Linux system.

 

Run Terminal: 

$ ls /dev/tty*

The we can see the device is detected by Linux Host OS:
