After about half a century of wearing denim jeans, I finally find a use for the ridiculous little coin pocket: it holds a stick pretty neatly!

Watched the excellent technical talk on USB4 (and related topics) by @MacLemon at #GPN22 https://media.ccc.de/v/gpn22-359-usb-wie-funktioniert-das-eigentlich-certified-usb4-version-2-0- Great speaker, good balance of technical and entertainment. I hope somebody will contribute english subtitles eventually. #usb #hardware #making

@LaF0rge @MacLemon Ah, I wanted to ask for a different talk anyway but maybe you know? How do you contribute subtitles for a media.ccc.de talk?

@LaF0rge Also, I’ve given pretty much the same talk in English at #BalcCon2k23

There are only minor differences since Thunderbolt 5 wasn’t yet public and it lacks the live demo I‘ve squeezed in for #GPN22

@schizanon it's such a fun upgrade. Even silly things like backing up devices to my NAS. It's so fast...

pro tip: label your usb cables with their capabilities. maybe your hdmi cables too.

Troubleshooting battery powered LED lights that quit working after a few weeks. No charge LED and measuring where the USB’s 5vdc is being lost I realize there isn't any at all, even at the jack. Remembering some of the usb-c spec, I try an A to C cable with old USB A power cube and the device starts charging. The C to C cable which charges an iPad doesn't do a thing.

After a little searching:
TL;DR: USB-A charging ports by default provide 5V to whatever is plugged in. USB-C charging ports don't.

https://www.reddit.com/r/UsbCHardware/comments/c3q4s6/why_do_some_usbc_devices_not_charge_with_a_usbc/

My guess is this cheap circuit board doesn’t have the CC resistors to signal the system that it wants 5v (it shipped with an A to C cable).

Frage zu USB:

EDIT: Beantwortet. Ich habe ein 5-V-Steckernetzteil gefunden und an den USB3-Hub angeschlossen, damit werden auch die neuen DVD-Laufwerke erkannt. Danke für die Aufmerksamkeit 🙂

Ich hantiere hier derzeit mit drei externen USB-DVD-Laufwerken, um meine DVD-Sammlung zu rippen. Eines davon hab ich schon länger, zwei habe ich vor einiger Zeit neu dazugekauft. Alle drei sprechen USB3, alle drei sind markenlos und aus China.

Bei den zwei neueren stand bereits im Angebot, daß man sie nicht über einen Hub betreiben könne. Die beiden hab ich tatsächlich vorne am PC hängen (eins davon aus Platzgründen am USB2), und sie funktionieren einwandfrei. Sie funktionieren allerdings tatsächlich nicht an einem externen USB3-Hub, den ich mir kürzlich zusätzlich gekauft hatte, weil mir vorn am PC die USB3-Schnittstellen ausgehen. Das ältere Laufwerk kann am Hub betrieben werden. Die Idee war eigentlich gewesen, alle drei an den Hub zu hängen.

Woran liegt das? Also, was unterscheidet die beiden neueren von dem älteren? Einsparungen in der Elektronik? Und: Läßt sich das im Nachhinein „enhancen“, also könnte man die Laufwerke so umbauen, daß sie auch am Hub funktionieren?

Habe schon 2x in meinem Leben VDD am USB A Stecker mit Tape abgeklebt.

Bin ich der einzige oder entscheiden sich andere auch für solches Gefummel mit der Pinzette?

bisher (noch) nichts in diese Richtung gehend unternommen.
Was hat dich dazu bewegt?

@meldrian ich will USB Host und Device mit getrennten Spannungsquellen versorgen, um ein HW Problem zu debuggen :) Da ist es hinderlich, wenn der USB auch Spannungsversorgung spielt.

Ignore the dust. This is the unit bearing the front USB3 ports of my PC case, a CoolerMaster N400. When opening this, I thought I would find a circuit board that I can easily trace and solder. Nope. It's just a piece of black plastic held together by dark forces. The lower port is broken. It works if I bend it upwards with considerable force, but it doesn't stay like that. I assume it's a broken solder joint and there's still a PCB inside. I wonder if the plastic would be able to withstand 150°C or so for 10 minutes. Maybe I could try reflowing it with the case on?

@rayko @fell yes there's no pcb inside i'm sure

@lamp @rayko Yeah nah. It's all glue in there. There's no way.

Just installed on my computer. Stupidly forgot to install and before rebooting though so now have no speech. Would any sighted person out there be willing to help me login, connect to the internet, and install what I need over a ? It shouldn't take too long, and I don't want to boot from the again. is great, but I'd prefer help from someone who knows .

Ugh, lol I'm impatient. About to say just forget it and boot from the USB again. I do need to eat, though, so maybe I should go do that and give this post some time.

@RareBird_15 I know linux (although not arch specifically) and I should be able to help. Would jitsi be ok, e.g. under https://meet.coredump.ch/doggy ?

Samsung Bar Plus 256 GB Stick vs. Kingston DataTraveler SE9 512 GB.

Beide sind relativ schnell, schlüsselbundtauglich und haben ein Gehäuse aus Metall (ohne Deckel).

Der Samsung kommt an meinen Schlüsselbund wegen der höheren Leserate. Der andere an den TV.

@inviridi meine Freundin sieht manchmal lineares Fernsehen. Da kann es ganz praktisch sein, auch mal "Pause" zu drücken oder etass Aufzunehmen. Für beides wird eine Festplatte oder ein USB Stick gebraucht.

@thomas Interessanter Anwendungsfall! Aber verständlich, immer nur Netflix ist ja auch langweilig.

I'm thinking about setting up a rule that triggers some actions when a given device is removed. For that I'd like a minimal device/token, think "only vendorid and productid", no actual functionality (which could fail and cause issues, etc.). Does anyone have a source for something like that? It's obviously ridiculously niche and not at all cost-effective to manufacture...

@lpwaterhouse you can do this with any USB device you can imagine. Do it with a flash drive. Doesn’t matter if the flash is corrupt or dead, you’ll never access the flash anyway.

🆕 blog! “Review: ACS ACR1251T-E2 USB Token NFC Reader II”
★★★★☆

Recap - I want to build an NFC reader expansion card for the FrameWork laptop. So I've bought a couple of components. This is the ACR1251T-E2 - it's a USB pen-drive sized NFC reader with a side-out USB-A plug. Costs about £40. There's a recessed green LED which flashes to let you know that it …
