安装CH340/341的串口驱动时，在网上搜索到很多要自己下载源代码编译安装的方法。其实最新版本的ubuntu已经完美支持。第一步，先找到USB设备,使用命令

lsusb

Bus 001 Device 002: ID 0409:005a NEC Corp. HighSpeed Hub
Bus 007 Device 003: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
Bus 008 Device 002: ID 1bcf:0002 Sunplus Innovation Technology Inc. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

找到usbserial设备的信息，这里是bus 007 Bus 007 Device 003: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter 然后装入usbserial模块, 根据结果修改vendor和product参数

sudo modprobe usbserial vendor=0x1a86 product=0x7523

最后看看是否成功安装

lsmod | grep usbserial

返回结果

usbserial               37161   1 ch341

有上面一行信息意味安装成功参考:http://forums.reprap.org/read.php?12,4546
