电脑如果COM口不够，可以使用USB转COM口线，将COM口转换成USB口。
COM口转USB线的使用方法：
1、首先准备一条USB转串口线，可以看到这种数据线一端是标准的USB口，可以连接笔记本的U口，一端是标准的9针串口公头，可以连接目标设备；
2、再来安装USB转串口数据线的驱动，驱动文件一般会在购买数据线时附送的光盘上面，也可以从网上下载；
3、双击setup驱动安装文件，将驱动安装到笔记本上；
4、将USB转串口数据线插到电脑的空闲USB数据口；
5、因为这种数据线增加的串口一般都不是默认的串口1，所以需要先查找一下新增串口的序号。打开【我的电脑】；
6、在【我的电脑】上点击右键，选择【设备】；
7、可以在【端口】的选项中看到新增的串口为【COM7】；
8、打开串口助手软件，在串口号的位置选择【COM7】；
9、点击【打开串口】，可以看到标志灯已经亮了，表示串口连接正常。这样就可以来通过这个新增的串口调试设备了。
