Could not find USB device 0x1781/0xc9f

[Archeious]

I am using a kit I purchased a kit and assembled it. The green light is lit.

When I try to using the arduino software to burn a new bootload I get the error message "Could not find USB device 0x1781/0xc9f"

I am using Vista 32bit. I am also getting the same message with avrdude. I know not where to start troubleshooting.

It not recognizing it as a USB device on either of my PCs (Vista 32bit or Windows 7 x64)

did you look at the sticky topic viewtopic.php?f=20&t=13005

[Archeious]

aye, I sure did. I turned off driver signing like it suggested and still no go.

[adafruit]

hmm. you have to restart perhaps?

[Archeious]

On my Windows 7 x64 machine it is showing up as a malfunctioning device.

[adafruit]

check your soldering just in case. also, did you manage to install the driver?

[Archeious]

Good call. It looks like the solder join on D2 got too hot and pulled up the trace.on the side that hooks up to D1. I soldered a jumper wire between to teh two and now I get a

Code: Select all

avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

I am trying to load in a new boot loader on a boardino (which I got from you guys a while back [and love it]). I will research the error but if it is something simple please let me know.

check our FAQ/HEEEELP section. we provide a lot of hints but now your programmer works

I have read the FAQ and help sections. Unfortunately they did not help me. I also think I bricked ym boardino. The red light won't even flash now. I swapped out with a preprogrammed 328 and it won't flash either.

well. ya something happened but if you didnt try to program the second chip its probably fixable.

I'm experiencing this same error while trying to load a sketch via the Arduino IDE over USB. I'm using an Arduino Duemilanove. I am able to program the device via my USBtiny and avrdude without problems. The usbtiny is not connected to the Arduino or my Mac when I try to program via USB. Furthermore I know the USB port works as I can receive serial data in the Arduino environment.

I am running Arduino 0019 on OSX. I've made sure I have the latest FTDI drives. I've also verified that the appropriate Board and Serial Port are selected. Finally, though I'm sure the correct bootloader was already installed, I have reinstalled it. Has anyone else encountered this problem?

TIA,
Dustin

you're confusing FTDI and USBtinyISP
they are not the same things, and dont use the same drivers
you should use the USBtiny to upload a new bootloader to your adruino. they use the USB port on the arduino to upload new sketches

I don't believe I am confusing FTDI and USBtinyISP. I understand they're different. I understand that I should not be seeing this error given the method of programming. None-the-less I am. When I try to program via the Arduino IDE (i.e. using USB) I see the error "Could not find USB device 0x1781/0xc9f" as though it's trying to use the ISP interface with the USBtinyISP. This is the source of my confusion and the impetus of my question.

Also, as I mentioned I did upload a new bootloader to my arduino but it did not correct the problem.

[adafruit]

if you're saying "The usbtiny is not connected to the Arduino or my Mac when I try to program via USB. Furthermore I know the USB port works as I can receive serial data in the Arduino environment.
I am running Arduino 0019 on OSX. I've made sure I have the latest FTDI drives."

that sounds like you're confusing the two

if you can program an AVR with avrdude, the programmer is working fine...you've probably messed up something with the IDE while experimenting. posting -precisely- what you're trying to do will be helpful. dont say 'program via USB' because that can mean many different things

I'm confused since the first thing I said stated precisely what I was trying to do... "load a sketch via the Arduino IDE over USB". I can only assume this is statement is unclear so I'll restate. I want to upload a sketch from the Arduino IDE to an Arduino Duemilanove. The error I receive while doing so is "Could not find USB device 0x1781/0xc9f". The aforementioned error implies that the Arduino IDE is trying to use a USBtinyISP to program the Arduino. However there is no USBtinyISP in play. The Arduino is connected to a MacBook Pro via USB and there are no other cables or devices in the mix. As far as the IDE goes, the only thing I did was install it, I've done no experimentation with it. This gives rise to two questions:

1) Can I program the device at all? Yes, if and only if I program it via ISP.
2) Is the USB connection working at some level? Yes, if I load a sketch that outputs serial data I can see that data in the Arduino IDE serial monitor.

So this leaves the question, why is the Arduino IDE trying to use a USBtinyISP when it should be using the USB connection?

My apologies for the confusion I hope that makes the issue more clear.

TIA,
Dustin
