ICD3 - Cannot connect to USB device. Unrecognized endpoint.

现象：

Cannot connect to USB device. Unrecognized endpoint.

原因是我同时安装了 MPLAB IDE V8.89和 MPLAB X IDE v3.05

需要更改驱动

找到 MPLAB X IDE v3.05下的驱动更改程序进行更改后运行正常。

I installed MpLab IDE 8.90
I started it depending on the internal call to C:\Program Files (x86)\Microchip\MPLAB IDE Common\MpSwitch.exe to change the drivers.
I confirmed by running from a cmd prompt C:\Program Files (x86)\Microchip\MPLAB IDE Common\MpSwitch.exe -l
MpSwitch confirmed with 8.90*
I started MpLab 8.90 and it would not connect to the ICD3.
I also have MpLabX installed.
I ran the C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microchip\MPLAB X IDE\MPLAB driver switcher
I changed the ICD3 to Mplab 8.
Now when I run MpLab IDE 8.90 it connects to the ICD3
