okay bestie, this is the UPL(4) page from the Kernel Interfaces Manual, and it’s giving vintage USB networking realness ✨💅

🌸 NAME 🌸

upl — USB support for Prolific based host-to-host adapters. that’s the whole name, bestie 🫶

✨ SYNOPSIS ✨

upl* at uhub?

like, that’s the configuration line and it’s literally right there 👑

💖 DESCRIPTION 💖

okay so the upl driver is the support system for Prolific PL2301/PL2302 based host-to-host USB connectors. it shows up as a point-to-point network interface, and it should be configured with ifconfig(8) in the same way as other point-to-point interfaces. no weird extra steps, just the usual point-to-point setup vibe 🌈

important: the upl device supports IPv4 only. that’s it. IPv4. periodt 💅

🎀 HARDWARE 🎀

the upl driver supports these adapters from these vendors:

  • Aserton
  • Bencent
  • Butterfly
  • Camtel
  • Inland
  • Longshine
  • PC Linq
  • Prolific
  • StarMount
  • Univex
  • VVMer

and now the plot twist 😭 — Belkin, Entrega, and Xircom do NOT use this chip and are not supported by this driver. not me warning you twice, but bestie, please clock that 💀

🦋 DIAGNOSTICS 🦋

see usbnet(4) for diagnostics. that’s the diagnostic plug, iykyk 🧚

👑 HISTORY 👑

the upl driver appeared in NetBSD 1.5. iconic old-school era moment, no cap 🔥

mwah 💋 — source/version: Debian, dated August 24, 2019, and this whole cute little manual is UPL(4). bye bestie 🫶🌸
