=USB driver not found=
 
==Problem==
 
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
 
 
==Solution==
 
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: [[:Media:180112_WinUSBDriverInstall.zip|WinUSBDriverInstall.zip]]
 
#Execute the InstallDriver.exe

=J-Trace detected as HP Printer BIDI=
 
==Problem==
 
J-Trace PRO is incorrectly detected as a HP printer device. This is a problem with the HP BIDI printer driver and Windows 7 / Vista. The wrong driver is assigned to J-Trace and it cannot be used with the J-Link/J-Trace software. This happens on PCs where the HP BIDI driver is installed '''before''' any J-Trace was ever connected to the PC. In order to fix this, the correct driver needs to be assigned to J-Trace manually. This only needs to be done once.
 
 
* Open the Windows device manager
 
* Open the USB devices tree. There should be a HP BIDI device shown which is really a J-Trace. (Check if the device is removed from the list if J-Trace is disconnected to make sure the correct USB device is selected)
 
* Richt-click the USB device and click '''Properties'''
 
* Go to the '''Driver''' tab and click '''Update Driver...'''
 
* Click '''Browse my computer for driver software'''
 
* Click '''Let me pick from a list [...]'''
 
* Select '''WinUsb Device''' and click '''Next'''
 
* Windows will show that the new driver has been assigned successfully
 
* Check that J-Trace is now correctly listed as WinUSB device
