A USB driver is a software bridge that allows your Windows PC to communicate with your Samsung B310E hardware. Without this driver, your computer will either not recognize the phone or label it as an "Unknown Device." For the B310E, which runs on a proprietary Spreadtrum (now Unisoc) processor, generic Windows drivers will not work.

Sometimes the standalone B310E driver doesn't exist. Instead, GSMForum members package it within larger collections. Look for:

Download any of these only if the thread title explicitly mentions "Samsung B310E tested."

Q1: Does the Samsung B310E USB driver work on Windows 7? A: Yes, perfectly. In fact, Windows 7 requires no signature bypass. The driver installs natively.

Q2: My B310E charges when connected but PC makes no sound. Why? A: The phone is in "Charge Only" mode. You need to force Download Mode: With phone OFF, press and hold Volume Down + Power simultaneously while plugging the USB.

Q3: Is this driver required for Samsung PC Studio? A: No. Samsung PC Studio (old software) uses a different proprietary driver. The GSMForum Spreadtrum driver is for low-level repair, not data backup.

Q4: I downloaded from GSMForum, but the ZIP is password protected. What is it? A: Genuine uploaders rarely password-protect. If protected, try gsmforum, samsung, or b310e as password. If those fail, delete it – it's a spam upload.

Q5: Can I use this driver on macOS or Linux? A: No. The .inf and .sys files are Windows-specific. For Linux, you need libusb and a custom udev rule, which is not covered on GSMForum.

Since many GSMForum users struggle with modern OS driver signing enforcement, follow this precise method.

If GSMForum links are dead, you can try the generic Samsung USB Driver v1.5.63.0 from Samsung Developers website. However, this driver does not always include the .inf entries for CDC ACM devices like the B310E. In that case, you must manually add the following lines to wpdmtp.inf or mdmcpq.inf:

%SAMSUNG.DeviceDesc%=SAMSUNG, USB\VID_04E8&PID_1234&MI_00

But honestly, the samsung b310e usb driver gsmforum community edition remains the most reliable.
