求高手解答win10系统安装usb转串口驱动失败？window10 usb转串口驱动

　　前两天从网上买的51单片机散件，焊接后电脑一直无法驱动成功，usb转串口用的ch340g的芯片，开始测量芯片晶振两边对地电压分别为5v.和0，经过确认芯片信息发现必须要用12M晶振才能驱动，焊接时用成了11.0592M，重新更换晶振后，测量两边电压分别为2.43v，2.39v，判断晶振已经起振（电压为VCC1/2）。

　　连电脑后还是无法检测到硬件信息，于是考虑是芯片问题，更换ch340g芯片，仍然无法解决，芯片电压VD+3.3V，VD-接近0V，检查后发现芯片各引脚均正常，无语了…

　　最后查资料怀疑是系统问题，我用的WIN10系统，于是下载虚拟驱动VMWARE和XP镜像文件iso，虚拟系统安装好后用对应版本ch340g驱动，设备信息识别成功！

　　有以下几种可能：第一种可能，硬件问题，或者接口问题。把usb转串口线接到不是usb3.0的接口试试，或者换一个新的。第二种可能，安装软件的时候没有以管理员权限运行。第三种可能，驱动和操作系统的位数（32位，64位）不符。
