  • Hey folks,
    I had to make an account to respond to this, because it might save a ton of frustration.
    It's true that you can build this circuit out of spec and it might work, but that can be dicey. I built something similar (attiny45 and v-usb) and I found that without the voltage regulation, only 1/3 of the computers I tried it on could recognize it as a usb device.
    It is absolutely worth it to slap on a few diodes to bring the voltage down to the 3.3-3.6 range to improve your chances for compatibility.

No public wish lists :(
