Using Arduino IDE with FabISP to program ATtiny85

Other Hardware 3rd Party Boards
1

hello,

in the past i've successfully programmed tiny45s and 85s using the arduino IDE and a variety of ISP programmers. right now i'm trying to use the fabisp to upload a sketch to a tiny85 and i get the following error message:

avrdude: usbdev_open(): did not find any USB device "usb"

checking my mac system report i can see that the fabisp is listed under USB > hub.

i've also tried adding the following lines of code to the programmer.txt file, because i know i need to edit something somewhere, but i always forget what i have to edit and where.

fabisp.name=FabISP
fabisp.communication=usbtiny
fabisp.protocol=stk500v2

if anybody can help, that would be wonderful! thanks.

Selected board?

in the tools > board menu i have ATtiny85 selected.

in the tools > serial port menu the FabISP does not show up, so nothing is selected. but i don't remember being able to select it in the past either.

that worked perfectly. thank you!

it was only slightly confusing because there are two boards.txt files, and at first i looked at the one alongside the programmers.txt file, which is in the hardware folder, inside the arduino application folder. here i found no mention of the ATtinies.
in the other boards.txt file, which is in the ATtiny45_85 folder in the hardware folder, inside the arduino sketchbook folder, i found the ATtiny code! which i replaced, and now all is good.
