The JP108 USB LAN adapter is a testament to the ingenuity of low-cost hardware, serving as a practical solution for adding network connectivity to older or specialized devices. While it can be frustrating to set up due to its "generic" nature, its broad compatibility, particularly with older systems and Linux via the DM9601 driver, makes it a valuable tool.
The drivers typically support a wide range of operating systems:
Supports 10/100 Mbps Fast Ethernet (Note: It does not support Gigabit 1000 Mbps speeds). Jp108 Usb Lan Driver

For the JP108, the most common hardware IDs are:
“030818” is believed to be a batch number or manufacturing date code (possibly meaning March 8, 2018). It does affect which driver you need. All JP108 adapters with or without that number use the same SR9600 driver.
If your legacy JP108 driver is blocked, you can temporarily disable driver signature enforcement. Hold down the Shift key while clicking Restart in the Windows Start Menu. Navigate to Troubleshoot > Advanced options > Startup Settings > Restart . Upon reboot, press 7 or F7 to select "Disable driver signature enforcement." Reinstall the driver. 6.

One Japanese user described it as a "dubious USB NIC" that was sold in Akihabara electronics district around 2010 for about 700 yen, packaged with nothing more than a CD-R containing the driver. Similarly, a Chinese user admitted to buying one from Taobao and finding that it was not recognized by his Linux system at all.
