, hot-plugging this module on my computer caused a blue screen. I'm not sure if it's a module issue or a system issue.
Anyone experiencing the same problem can share their feedback in the comments. The SR9900A(I) is a highly integrated, low-power, single-chip USB 2.0 to 10/100M Ethernet control circuit.
It
adds low-cost, small-package, plug-and-play Fast Ethernet functionality to various applications, including desktops, laptops, ultra-portable computers, tablets, docking stations/port replicators/extension stations, game consoles, smart home devices, and any embedded device with a USB interface.
The SR9900A(I) integrates a USB 2.0 transceiver, a 10/100M Ethernet module based on IEEE 802.3 and IEEE 802.3az-2010, and a high-efficiency memory control module.
The SR9900A(I) is fully compatible with Microsoft's NDIS5 and NDIS6 (IPv4, IPv6, TCP, UDP) checksum features. It supports IEEE 802 IP2 layer priority coding and IEEE 802.1Q Virtual Local Area Network (VLAN).
Note that
the SPI FLASH on the board can be left unsoldered without affecting usage; the PCB can be modified to remove the Flash. This chip is in a very small QFN package; for those with poor soldering skills, it's recommended to use solder paste, stencil, and a hot plate in one step. 10cm x 10cm stencils are available for around ten yuan on Taobao.
Linux, macOS, and Android are driverless; Windows requires a driver. The attached file contains the driver package; see the steps below for installation.
Actual speed test averages 94.7Mbps.
Windows driver installation method:


Download the driver package from the attachment.


Extract the SR9900_V2.0.3 folder from the package to C:\Windows\System32\drivers.


Open Device Manager, find USB 10/100 LAN under Other devices, right-click and select Update driver. In the pop-up window, click Browse my computer for driver information.


Click the Browse button to find the copied driver folder, check Include Subfolders, and then click Next to start the driver installation.


If the installation is successful, you should see the network adapter name.
