I know this topic has been covered before, but I have not been able to find a solution to my particular situation. I am using an AVR ISP MKII programmer with a custom board. The board is essentially just a pro mini 3.3V with a few other components added to it. when I hook the board up I get a green light on my programmer, but when I try to program the board, I get the following error.
avrdude: usbdev_open(): did not find any USB device "usb"
I manually installed what I thought was the correct driver for the ISP.
When I look at the driver details it tells me the following list of driver files:
C:\Windows\system32\drivers\libusb0.sys " "\libusb0.dll C:\Windows\system64\libusb0.dll
That's all the relevant info I can think of at the moment. I'm at a loss. Oh, I should also add that at the bottom of the IDE window it says the following: Arduino Pro or Pro Mini (3.3V, 8MHz) w/ Atmega168 on COM4.
I was happy when I saw that thinking it meant it recognized it...but still the same error. Thanks!
