The connection assistant is not able to detect the PEmicro hardware. The first step is to make sure that the USB Multilink or Cyclone hardware is connected to the PC via a USB cable. If so, plug and then unplug the USB cable from the interface and click refresh in the connection assistant. The second step is to make sure that the Multilink is not being used in another software. If the hardware still does not show up, see the following remedies:

The device also supports a dedicated charging-port (DCP) mode when the upstream port is not connected. The DCP mode is compliant with the USB battery charging specification and Chinese Telecommunications Industry Standard YD/T 1591-2009.

(A) Re-Enable the USB driver

If you connected the Multilink/Cyclone interface prior to installing the drivers, Windows will not have been able to find the appropriate driver and may have disabled the device. On the Multilink, this will cause the Blue LED to not light up. If you unplug and re-plug in the device, Windows will automatically disable it even if you have installed the drivers. To force Windows to try and load the driver again, perform the following steps while the USB interface is connected to the computer:

1.) Open the Control Panel (Start Button->Settings->Control Panel)
2.) Double Click the 'System' Icon
3.) Select the 'Hardware' tab
4.) Click the 'Device Manager' Button
5.) The category Jungo should appear there. Expand out the Jungo tree. There will be two devices shown depending on your version of Windows. In Windows 8 and below, you should only see 'WinDriver'. In Windows 10 and newer, you should only see 'pemicrowindrvr'. Then you should see 'USB Multilink 2.0' or 'Cyclone/TraceLink'. They may have a warning (yellow exclamation mark) next to it. Double click this device.
6.) Click the 'Reinstall Driver…' button and follow the dialog instructions for having Windows automatically install the driver.

(B) Re-Install the USB driver

If either of the two devices do not show up in the device manager, download and run the driver install package appropriate for your Windows version (attached to this FAQ). Driver for wireless card.

(C) Uninstall old USB drivers

If multiple versions of drivers exist on your PC, Windows could be loading an old driver version that is incompatible. This can occur if you updated Windows, for example.

For Windows 10 x64 users, perform the following steps to remove the old drivers:

1.) Open a command prompt (you may need administrator privileges) and list all installed driver packages into a text file:

pnputil.exe /enum-drivers > pemicro.txt

2.) Remove all of the inf files for windrvr6.inf. Look in the text file for all drivers where the 'original name' is windrvr6.inf. For instance, you might see the following example:

Published Name: oem163.inf
Original Name: windrvr6.inf
Provider Name: Jungo Connectivity
Class Name: Jungo
Class GUID: {c671678c-82c1-43f3-d700-0049433e9a4b}
Driver Version: 09/23/2013 11.4.0.0
Signer Name: Jungo LTD

You should remove it with the following command:

pnputil.exe /delete-driver C: Windows inf oem163.inf

Repeat the previous step for all oem*.inf where the original name is windrvr6.inf until they have all been deleted.

3.) Open another command prompt (you may need administrator privileges) and manually uninstall the existing devices in device manger:

Go to the directory C: PEMicro PEDrivers supportfiles Drivers_12_7_0 windriver and type the following commands:

wdreg_gui.exe -inf pemicrowindrvr.inf -log pemicrowindrvr.log uninstall

wdreg_gui.exe -inf pe_winusb_interface.inf -log pe_winusb_interface.log uninstall

wdreg_gui.exe -inf windrvr6.inf -log windrvr6.log uninstall

4.) Delete the following files from your Windows directory if they exist:

C: windows syswow64 drivers pemicrowindrvr.sys

C: windows system32 drivers windrvr6.sys

C: windows syswow64 peusb32bin64os.dll

C: windows syswow64 peusb64bin64os.dll

C: windows syswow64 peusbmgr.dll

C: windows syswow64 peusbmgr2.dll

C: windows syswow64 peusbmgr264.dll

Also delete any files that are peusbaXX.dll and peusbbXX.dll if they exist.

5.) Open another command prompt (you may need administrator privileges) and manually install the drivers:

Go to the directory C: PEMicro PEDrivers supportfiles Drivers_12_7_0 windriver and type the following commands:

wdreg_gui.exe -inf pemicrowindrvr.inf -log pemicrowindrvr.log install

wdreg_gui.exe -inf pe_winusb_interface.inf -log pe_winusb_interface.log install

6.) Restart your PC.

(D) Scan for Hardware Changes

Drivers Yep Telecommunication Port Devices Download

If you tried the above remedies and the issue still isn't resolved, let's try to force Windows to re-initialize the connected USB interface. Keep the USB device connected.

1.) Open the Control Panel (Start Button->Settings->Control Panel)
2.) Double Click the 'System' Icon
3.) Select the 'Hardware' tab
4.) Click the 'Device Manager' Button
5.) Expand out the Jungo tree. Right click on 'WinDriver' or 'pemicrowindrvr' and select uninstall driver (check the box to delete the 'driver software for this device' if it exists).
6.) Go to the toolbar and click Action -> Scan for hardware changes.
7.) Repeat this process for all other drivers such as 'USB Multilink 2.0', 'Cyclone/Tracelink', or 'PEmicro OpenSDA Driver'

These steps should also help if your device is reporting an error or warning (it displays a yellow exclamation mark).

(E) Test for installation of the USB driver files

To test the driver installation, download the driver test utility attached to this FAQ. This will check to make sure all files were properly installed. Select the appropriate version of Windows in the utility to check. This may give some indication of what the problem is.

(F) Using a USB Hub

The USB MULTILINK is a high power USB device that draws 500 ma of current from the port. If a USB HUB is used, it must be a self-powered hub (i.e. with a power supply). If the HUB is an unpowered device the USB MULTILINK will not work. USB ports directly on the PC are high-powered (self powered) ports, in general. However, some front panel or laptop USB ports may not be high-powered.

(G) Update Your PEmicro Software

To ensure that your PEmicro software is compatible with the latest drivers and firmware you should update the software. Licensed users of our software are entitled to cost free updates for one year. If your purchase was more than one year ago, please contact us for pricing.

If you receive this error Windows cannot load the device driver (Code 38) in the Device Manager, it means that a previous instance of the device driver is still in memory. Every time a device is used, the driver is loaded into memory, and then unloaded.

Bothered by Windows 10 USB Error Code 38

Each time you connect external devices like scanners, printers and the likes to a Windows 10 computer, the device either pushes the drivers through the USB or any other port or you are expected to install the drivers through an external media. In both cases, the driver will be loaded in the system, allowing you to use the device. However, it doesn’t always go smoothly as you could encounter some errors like the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory (Code 38)”.

Top Reasons for Error Code 38 Windows 10

To help you better understand this Windows cannot load the device driver for this hardware code 38 error, we summarize some main causes as follows:

These things might cause Windows cannot load the device driver for this hardware code 38. Focusing on them, we introduce some solutions for you. If you are not sure which is the real cause of the error, you can try these methods one by one until you find the suitable one.

Solution 1: Make Sure the Hard Disk Is Never Turned off

Perhaps, you don’t know that the hard disk on your computer is set to be turned off after a certain period by default. If the Windows 10 Device Manager Error Code 38 issue happens to an external hard disk, you can go to check and modify the settings in Power Option to make sure that the hard disk is never turned off.

Here is a guide on how to do this job:

1. Click the Windows search box and type Control Panel.
2. Select Control Panel from the search result to open it.
3. Click Power Options.
4. Click the Change plan settings link that is next to Balanced (recommended) in the Preferred plan section.
