RTL8192EU 802.11b/g/n WLAN Adapter

[Andrew Randrianasulu <randrianasulu%gmail.com@localhost>]

I have this device plugged right now into box, running Slakware 15.0
i586 with custom kernel:

Linux slax 6.12.26-x64 #1 SMP PREEMPT_DYNAMIC Sun May  4 23:16:06 MSK
2025 x86_64 AMD FX(tm)-4300 Quad-Core Processor AuthenticAMD GNU/Linux

Unfortunately, when I booted into my self-compiled back in May NetBSD
kernel device failed to scan wifi (via wpa_cli) and when I updated
kernel to snapshot:

wget https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/20250913234600Z/amd64/binary/kernel/netbsd-GENERIC.gz

https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/20250913234600Z/amd64/binary/sets/modules.tar.xz

It just outright disappeared among with amdgpu ....

Inability to scan might be related to  this (solved by now) Linux bug:

https://bugzilla.kernel.org/show_bug.cgi?id=216746

But in my experience networks and their SSIDs were visible on bugged
Linux kernel module, just authentication failed.

lspci -v from Linux:
