As @bpl said, check the kernel messages. The messages that you show in that photograph indicate that although nine root USB hubs have been found, no USB keyboard or even mouse devices have been enumerated.
You have a mass storage device on hub 3, an ELAN device on hub 3, a camera on hub 4, a BlueTooth node on hub 4, and nothing else. No keyboard/mouse HIDs at all.
The ELAN device is a fingerprint reader.

An external USB keyboard should work. Everything that I can find indicates that on Thinkpad E14s the keyboard is actually a PS/2 keyboard (sic!). So look at the part of dmesg that scrolled off your screen that deals with PS/2 device enumeration.
There's also some bizarre extra PS/2 stuff related to that Elan USB device, but that's to do with your fingerprint reader/trackpad.

I was reading through the #OpenBSD documentation and ran into a small but revealing detail: in OpenBSD 5.6, released in 2014, the project didn’t merely disable Bluetooth by default it removed the Bluetooth subsystem altogether.
The official release page simply lists “bluetooth” among the utilities removed from the base system, while the 5.6 changelog gives the blunt explanation: “bluetooth(4) support removed (code did not work properly anyway).”
What I find interesting is that this was not presented as a grand statement that Bluetooth itself was inherently unacceptable or impossible to secure.
OpenBSD had carried Bluetooth support before: its historical changelog shows that parts of the #NetBSD Bluetooth stack were imported and that Bluetooth drivers were later added to the generic kernel configuration, though initially not enabled. There was even a driver, ubt(4), for #USB #Bluetooth #adapters in OpenBSD 5.5.
So, the practical reason OpenBSD dropped it in 5.6 was much simpler: the code was not working properly, which strongly suggests it had become difficult to maintain and could not meet the project’s expectations for reliability and code quality.
Rather than leaving behind a feature that existed mostly on paper, behaved unpredictably, or accumulated unreviewed complexity, the developers chose to remove it.
In many systems, keeping a feature can feel safer because users may rely on it someday. OpenBSD often takes the opposite view: unsupported or broken code is not really a feature it is maintenance debt, potential attack surface, and a promise the project cannot honestly keep. Removing it makes the system smaller, easier to audit, and clearer about what actually works.
My takeaway from reading this is that OpenBSD 5.6 did not abandon Bluetooth because of a single dramatic vulnerability or because wireless hardware was categorically forbidden.
It removed Bluetooth because the implementation was not in a state the project considered worth carrying forward. It is one of those deceptively small release-note lines that reveals a bigger principle: for OpenBSD, a feature has to earn its place through working, maintainable code not merely through demand or familiarity.

Do such cables exist that allow me to connect a USB-A into a computer or whatever and another USB-A to a power source and that would all go into a micro USB type B slot?
And if those exist, how much are they? What are they called? Who makes em??
I'm having some power reliability issues that I need to solve for a project. And yes, it involves USB gadgets and Linux.

🆕 blog! “Why don't smart watches use USB-C to recharge?”
It looks like the new Google's Pixel 4 watch comes with yet another incompatible change in charging technology. This is a ridiculous situation.
The original Pixel Watch used one type of wireless charging. Then the Pixel Watch 2 & 3 removed wireless charging and swapped to a different charging mechanism. And…

Assuming you have USB Thumb Drive that has two connection points being the 'latest' USB-A and USB-C versions connectors
Is the USB-C faster? or are they the same.

If any of you guys use a JMicron JMS578 SATA 6G -> USB 3.0 Adapter (USB: 0x152d 0x0578) you may want to get some drop-in replacements as they may die after a year or so of 24/7 use...
- Don't ask me how I found out...
Not shure how and why it died.
- Drive behind it was fine tho...

Yet another toot regarding #FreeBSD and #tvheadend with a #Hauppauge WinTV duoHD - while it is possible for me to pass the #v4l2 driver via #webcamd to the userspace and actually get DVB devices like /dev/dvb/adapter01 etc. the programs I want to use with these devices just won't work properly.
Unfortunately, tvheadend or the commad line tool w_scan simply can't find any station over DVB-C. Using the same hardware that works without problems on Linux. Meh.
So one solution I found is to set up a #bhyve instance on your FreeBSD desktop system runing Linux/tvheadend and then pass the #usb #dvb device through to that bhyve instance.
Sounds a bit like cheating - after all I want to replace my infrastructure Linux server (serving CUPS, dnsmaq and tvheadend) with FreeBSD .
But if that's the only way for FreeBSD to handle DVB-T2 devices, then it shall be that way ... (I only hope that it will work) 🤷

🆕 blog! “I'm a USB-C Maximalist”
My wife and I recently went on a 7 week holiday around Europe. Although we each took a massive backpack, we wanted to travel fairly lightly. I took a single universal power brick. This little unit was all I needed to charge my various gadgets.
It has a hefty USB-C PD (Power Delivery) port for rapid charging of my phone and laptop. Two other USB-C…

Para la colección de reliquias: el manual original de la Epson Stylus Color 600, de 1998.
Imprimió miles de páginas esa maquinita, conectada con puerto paralelo DB-25 a la compu, y con un conector que se llamaba Centronics, de 36 pines.
No sabía lo que era el USB.
Tantas páginas, mitad ES, mitad PT, y creo que no ha sido leído por nadie 🤔
BTW, debe estar en una caja guardada ahce décadas... calculo que se habrán secado los cabezales 😅
