What is a Base System Device?

A Base System Device is a problematic hardware device marked by a yellow warning symbol, and is listed under “Other Devices” category in the Device Manager. The term “Base System Device” is not really a device name – it may refer to a generic card reader or the built-in smart card reader of your PC, but there are also cases when the base system device is actually a component of your chipset device.

The main reason why Other Devices Base System Device occurs is because the required device drivers that initiate the connection between your computer and the device are missing or are not installed.

The above images came from my friend’s Windows-7-based laptop which I borrowed for a night, and was surprised to discover that his laptop had three Base System Devices. And unlike other problematic devices that I encountered, the Device Manager was unable to display the Device Name or Type; it only adopts the phrase “Base System Device,” making things difficult. And as usual, clicking the Update Driver Button had no results.

Base System Device Roles and Possible Issues

Once again, the main reason for these problems to occur is device driver related. Most of the time, the correct drivers are missing or they have not been installed yet.

If the Other Devices Base System Device is either a card reader or the built-in smart card reader, then you will be unable to use these card readers until the problem has been fixed. But if it’s a chipset component – then you will need to fix it immediately to prevent serious PC problems.

A chipset plays a vital role in determining system performance, and it controls the communication between the processor of your PC and the external devices attached to it. Some roles of a chipset component may range from connecting the CPU to high-speed devices such as graphics controllers, and integrated peripherals like an Ethernet card. For example, Intel Technology claims that a Base System Device in a PC using Intel Chipset is a component of Intel® I/O Acceleration Technology – improves data flow to enhance system performance.

Options for Fixing Base System Device Problems

Generally speaking, fixing problems associated with missing device drivers is not too hard if you know the identity of the problematic device and have the  driver backup or installation CD. But that’s not the case with Base System Devices, since the Device Manager doesn’t provide the Device Name and Type.

Here are two options that you can undergo to fix a Base System Device trouble:

  1. Using the Installation CD – Since you don’t have any clue, you can install the chipset drivers, and then check if there is no more Base System Device listed under the Other Devices category. If it’s still there, you can try to install the drivers for SD card reader or for the smart card reader, and check again your Device Manager. If the trouble still exists after installing these drivers, you can try to search online.
  2. Searching Online – In case of our example, I searched online to find the required device drivers, since we had no available installation CD. Well, for a newbie, searching online without any clues will be very hard. You can start by searching what a Base System Device is, and you will find same results as explained above. One thing which will give you useful clues regarding the identity of a Base System Device is the ID’s available in the Device Instance Path of a Base System Device. To access this information, double-click the Base System Device, click on the Details tab, and then select the Device Instance Path. As for our example, VEN_197B stands for Vendor ID = 197B, and DEV_2382 stands for Device ID = 2382.

Since hardware IDs belong to a specific device, you can use VEN_**** and DEV_**** as search keywords in the “search box.” To remove worries of installing wrong or outdated device drivers, I went through “Device Search” and “Vendor Search” in PCIdatabase.com. There I found out that the Base System Device is actually a JMN38X SD/MMC Host Controller, and the official website of JMicron Technology was also provided – where I downloaded the device drivers, and then installed them on the laptop. After installing the drivers, I checked the Device Manager and there was no more Base System Devices, nor the Other Devices category! This time, SD devices were listed under the “Memory Technology Driver” category.
