Jp108 Usb Lan Driver [upd] -
1. What is the JP108? The JP108 is a USB 2.0 to 10/100 Mbps Fast Ethernet adapter . It lacks a true manufacturer; instead, multiple Chinese factories produce it using reference designs from ASIX Electronics (typically the AX88772A chipset) or, less commonly, the SR9900 (a clone of the AX88772).
Connectors: USB-A male, RJ45 female. Speed: 100 Mbps max (not Gigabit). Bus: USB 2.0 (backward compatible with USB 1.1). Power: Bus-powered, no external supply needed.
2. Driver Compatibility – Complete Table | Operating System | Native Support? | Recommended Driver | Common Issues | |----------------|----------------|--------------------|----------------| | Windows 11/10/8.1/8/7 | Partial (auto-installs generic driver) | ASIX AX88772A v3.x or later | Driver signature errors; old versions cause blue screens | | Windows XP/Vista | No | ASIX AX88772A v2.x | Manual install required | | macOS (Intel & Apple Silicon) | Yes (built-in for AX88772) | AppleUSBEthernet (native) | None – plug and play | | **Linux (kernel 2.6+) ** | Yes | asix or ax88179 module | May need modprobe asix | | Android | No (unless device has OTG + custom kernel) | Third-party apps (e.g., USB Ethernet) | Unreliable; only specific apps work | | Chrome OS | Yes | Built-in | May require enabling “USB Ethernet” flag | | Nintendo Switch | No (fails with “Unsupported device”) | None | Requires specific chipset (AX88179 or RTL8153) | | PlayStation 4/5 | No | None | Not recognized; Sony whitelists only certain chips | | Raspberry Pi (Raspbian) | Yes | asix module | Works out of box |
Critical note: Some JP108 units use a fake chip ID . Always verify with lsusb (Linux) or Device Manager (Windows) – real ASIX VID is 0b95 , PID 7720 or 772a . Jp108 Usb Lan Driver
3. Performance Review | Metric | Result | |--------|--------| | Max throughput | 85–92 Mbps (real-world TCP) | | CPU usage (USB 2.0) | 5–15% (depends on host) | | Latency increase | +0.3–0.8 ms vs built-in NIC | | Packet loss (under load) | ~0.1–0.5% (poor cables worsen) | | Wake-on-LAN | Not supported (no magic packet) | | Jumbo frames | Not supported | | VLAN tagging | Not supported | Verdict: Acceptable for web browsing, printing, light file sharing. Not suitable for gaming (latency spikes), streaming 4K, or large NAS transfers.
4. Installation Guide (Problematic Cases) Windows – Driver fails to install (Code 52 / Code 10) Solution:
Download official driver from ASIX website (not random CD or third-party site). → Search “ASIX AX88772A Windows driver”. Disable driver signature enforcement (Windows 10/11): It lacks a true manufacturer; instead, multiple Chinese
Shift + Restart → Troubleshoot → Advanced → Startup Settings → Disable driver signature enforcement.
Install manually: Device Manager → Update driver → Browse → Let me pick → Have disk → point to .inf .
Linux – Not detected or shows usbnet but no link Solution: sudo modprobe -r asix sudo modprobe asix sudo ip link set eth1 up Bus: USB 2
If still fails, check dmesg | grep -i asix – counterfeit chips may need option driver with manual VID/PID override. macOS – Works but disconnects after sleep Fix: System Settings → Energy Saver → Uncheck “Put hard disks to sleep when possible”. Or use a powered USB hub.
