J-Trace PRO USB driver problems
J-Trace PRO V2 Cortex-M and J-Trace PRO V2 Cortex do not use the SEGGER USB driver like J-Links do, but they use WinUSB instead. WinUSB was distributed by Microsoft via Windows Update so in case a USB device needed WinUSB, Windows downloaded it automatically in the background, where necessary. However, Microsoft changed their policy for Windows Vista / Windows 7 and WinUSB is no longer distributed via Windows Update. This may now lead to "no USB driver found" like problems when connecting J-Trace PRO to a PC for the first time.
Affected Operating Systems
- Microsoft Windows 7
- Microsoft Windows Vista
The easiest way to solve the driver issue is to install the required drivers manually. Please find below a step-by-step instruction:
- Download the following archive: WinUSBDriverInstall.zip
- Execute the InstallDriver.exe
