Hi,
So I'm trying to upload code to my Trinket, but my computer won't recognize that the Trinket is plugged in. I have the latest IDE, I'm on Mac (so no drivers), I've installed the Trinket board, and I'm using a USB 2.0 hub.
Help please.

Are you using the USB interface or the FTDI interface? Try pressing the reset button on the Trinket.

I'm using the USB interface, and it just says
avrdude: usbdev_open(): did not find any USB device "usb"

Re: Uploading Code to Trinket
Ok so after some time I think the IDE recognizes the microcontroller, but now after I push the button on the Trinket and upload the basic Blink example code, it says
avrdude: Expected signature for ATtiny85 is 1E 93 0B
Double check chip, or use -F to override this check.
Wrong microcontroller found.
What on earth does that mean and how do I fix it?

The device is only available while the bootloader is running. If you press the reset button just before the upload starts, it should start running the bootloader. You can tell it is in the bootloader when the red led is pulsing.

Yes I know that - I push the button and the red LED is pulsing and I get the error message I mentioned before.

Good. That means that the bootloader is running. Try a different USB cable or USB port. USB 2.0 ports generally work better than USB 3.0 ports.
