How do i flash this to the attiny85?

You will need an In System Programmer (ISP) hardware device and some software such as avrdude. If you don’t have an ISP there are a few inexpensive ones that work well. You also will need to connect the AtTiny85 to the ISP. If it is soldered the the board you’ll need a chip clip to connect to the pins.

I have connected a blank ATtiny85 to a Raspberry Pi, and flashed onto it a .hex file I have obtained by reading the programmed ATtiny85 from a BlinkStick Pro kit. The "copy" doesn't work -- when I insert it into the BlinkStick Pro kit's DIP-8 socket, the BlinkStick Pro doesn't even get enumerated on the USB bus...

I must be missing something...
