I finally finished this custom USB Controller using a 12 position switch. The customer will be using it as a USB MIDI Controller where they want to select 11 different settings.

It's a bit taller than I'd like but the switch is pretty tall and I need a certain amount of space for the PCB and controller.

The enclosure is 3D printed and so is the knob. The multi-color prints for both came out great.

I want to throw out a big #HotDamn to 20 years of #softwaredevelopment . I recently bought a used #Behringer #BCF2000 which had a #SysEx editor last developed in 2004 in #Java available for download from the official website. I downloaded the software to my #Fedora system and it recognized the device over the modern #Linux #USB interface and worked like a champ.

Well done, 20 years of #software develoment and backwards compatibility!

I've just listened to an #ITSecurity presentation, which gave me a few more nightmares to worry about.

First, there is #Shodan , a search engine for the #Internet (as opposed to the World Wide Web), aka "how to find hackable things on the Internet". If you have any devices accessible via the Internet - such as security cameras - it can probably be found there. And there are numerous people and companies who leave these devices unsecured - as the presenter demonstrated.

Also, #USB cables exist which look like the real thing but contain secret WLAN access for hackers. They cost around $200 these days, and can only be distinguished from the real thing by #CT scans.

It is 10:20 Central European Time. Do you know what your networks are doing?

Has anybody found a USB-C ethernet adapter that also does PoE to USB-PD?

I'm thinking something that could be plugged into a Pi4 or 5 that powers and adds a second ethernet port.

one #goBags tip i have is to get some of #Waterfield (aka #sfbags) gear pouches or #bellroy's fantastic zipper tech valets. you can put a large capacity 29000mAh+ power bank, some a-to-c c-to-c a-to-mini|micro #usb and room for adapters and wall chargers too. zip the little guy together and toss in your bag. i have two and i pull one when i am taking a trip that doesn't involve fleeing the country.

again, bellroy is a #bcorp and you'll love their gear.

I've been using RUFUS, but saw Etcher and thought, shiny, let's try it, then I catch this 411, and all those happy thoughts went away.

So yeah dammit, this is why we can't have nice things.

Yup, it's been a while since I've touched this #USB hard drive.

Hello Linux friends. Is there any way to use my computer to test USB-C cables?

I want to plug both ends of a cable into two different USB ports on my laptop.

I want to see the emarkers, resistors, and any other data about the cable. Maybe even run a speed test?

Is there a Linux utility which will do that?

(Yes, I know I can get external dongles. I want to do it locally without buying more stuff.)

77 commits later, and #libobscura has a scripting system good enough to initialize a #USB #Camera

So it's back to the same functionality, except with extra complexity, lol.

Next up: organize the commits (don't leave a mess if you want contributors) and make sure #librem5 works the same way.

First time I've ever experienced plugging in a new keyboard and it not Just Working.

Turns out: some new keyboards need usbhid stuff set up in FreeBSD. They work in console, but not in Xorg, otherwise.

Problems with booting Ubuntu Server 24.04.1 LTS on my Raspberry Pi 4 from usb hard drive #boot #systeminstallation #usb #harddrive #raspberrypi

I bought a couple of these MicroCenter #USB #flash drives yesterday and I'm going to have to return them because they get **very** hot to the touch after being plugged in for a few minutes, even with no file operations going on.

https://www.microcenter.com/product/669747/micro-center-512gb-dual-type-a-type-c-2-in-1-rotate-superspeed-usb-32-(gen-1)-flash-drive-silver

The ID is 2450:0512 but 2450 isn't a recognized manufacturer code; the packaging only says it was made in Taiwan. So this is a warning not to get the ones with the metal casing, but also a request to see if anyone knows who the maker is.

Cleaning task for today done! Washed and dried the USB flash drive in the washing machine

(still working, LOL)
#cleaning #usb

#Tech question:

I have two #USB 3 slots on my computer, but it seems like they cannot perform I/O operations simultaneously, e.g. moving files from one connected flashdrive to the other, whilst it is no problem to do so from a device connected to one of the USB 2 slots to one connected to a USB 3 slot.

Is this normal behaviour, is it a #Linux issue or is it just my computer?

Note: I can connect 2 devices to the USB 3 ports, use them after the other, without disconnecting one.

How can one retro-fit a #USBA port to a 10 year old #thinkpad when the #minipcie internal USB port card device (see link below) is not on the #lenovo #whitelist e.g. of a #thinkpad_x230
BTW the #usb port is for then fitting a #lora #rnode or #meshtastic #note inside the #laptop case. This video shows the problem.
