wonder if this would be a much better hw solution for TeslaUSB...

#32Literally converting it into a successful Mac accessory itself is a kickstarter gold!
Re: Raspberry Pi 4 as a USB-C peripheral
#33Yay, that feature was previously only available on the Pi Zero. Does anyone know if this will work on older computers, using a USB A-to-C cable?
Yep, should work fine with a USB-A to USB-C cable as well
Re: Raspberry Pi 4 as a USB-C peripheral
#34I fail to imagine a usw case for that. Could someone enlighten me?
... build a smart boot device that provides a bunch of different CD images for BIOSes that don't do USB boot well ... build a safe password keeper that looks like a HID device ... do something interesting with USB-based gamepads to map those to keyboard keys for playing old DOS games ... make a connected USB storage device that offers some sort of additional sync services for the data stored on it (maybe over wifi?)…

There are a few of those around.
Re: Raspberry Pi 4 as a USB-C peripheral
#35You can also do a USB client on a $1.50 AVR chip: https://www.obdev.at/products/vusb/index.html Source: Compiled and connected a mouse/keyboard firmware running on an ATtiny861a using internal RC oscillator.
Why would you do that though when there are a gazillion Cortex-M chips available that support hardware USB? Fast USB and you don't have to use AVR.
Hell, Atmel even sells Cortex-M chips with High Speed USB-2 support (reasonably hard to find; most are only Full Speed).

Full ATmega32U4 board is 2.50 and doesn't need any hacks to work.

#38Fyi: USB-c in the rpi 4 is not standards compliant.
A new revision is underway, a fix is just using dumb cables.

Does anyone know if any such similar devices are already available? Whether based on an RPi or not?

Could you provide a link to that $2.50 price?
