If you’ve landed on this page, chances are you’ve just plugged in a new piece of hardware—likely a barcode scanner, a receipt printer, a USB hub, or an embedded device—and saw “SC GKDL USB2.0” pop up in your Device Manager with a dreaded yellow exclamation mark.
You’re not alone. The “SC GKDL USB2.0” driver is one of those generic-sounding yet frustratingly specific drivers that Windows often fails to auto-install.
In this post, we’ll break down what this driver is, why you need it, and—most importantly—exactly how to install it.
Microsoft maintains a vast driver repository. For many OEM devices, the SC GKDL driver is distributed via Windows Update.
Since "SC GKDL" is a generic chipset name, you need to identify the actual device.
Since SC GKDL usually masks a standard serial bridge chip, try one of these drivers:
For CH340/CH341 chipset (most common):
For PL2303 chipset:
For CP210x:
After installing, go back to Device Manager, right-click the device, and select Scan for hardware changes. The name should change to “USB Serial Port” or your actual device name.
Q1: Can I use the SC GKDL USB2.0 driver on Linux or macOS?
Q2: My device is a fingerprint reader, not a smart card reader. Will this driver work?
Q3: Why does this driver keep reinstalling itself after I delete it?
Q4: Is there a 64-bit version of the SC GKDL USB2.0 driver?
Be very careful when Googling obscure codes like "sc gkdl driver." Many "Driver Update" websites that appear in search results are actually malware or adware.
Summary: "sc gkdl" is likely a generic USB device. If Windows 10/11 doesn't install it automatically, use the Hardware ID in Device Manager to find the true chipset manufacturer.
If you're looking for the driver, here are some possible sources:
If you're experiencing issues with the driver, here are some common problems and potential solutions:

: If the driver fails to install automatically, users often need to manually select "Update Driver" in Device Manager and browse to the extracted driver folder. Virtual Hub Conflicts
: Some boards, like the Arduino Leonardo, use a virtual hub that may cause the Device Manager to refresh multiple times, potentially leading to timing issues during sketch uploads. Port Specificity : Users have reported better stability when using USB 2.0 ports
specifically, as some legacy CH340 drivers may struggle with USB 3.0/3.2 ports Arduino Forum Installation Best Practices Download from Trusted Sources
: Use official manufacturer sites or reputable repositories like DriverScape to avoid malware. Manual Installation
: If the executable fails, use the "Let me pick from a list" option in Device Manager to manually point to the Check COM Port
: Once installed, verify the assigned port (e.g., COM3) in the "Ports (COM & LPT)" section of Device Manager to ensure your software (like the Arduino IDE) is targeting the right location. Arduino Forum troubleshooting a specific error code?
