AVRISP mkII pogrammer was working but is now failing

I am tearing my hair out over this.  I have received an AVRisp Mk2 this morning.  I initially got avrdude: usbdev_open(): did not find any USB device "usb" so I followed the instructions to create a libusb-win32 inf file and installed that driver.

All worked great for about 15 minutes when it stopped working.

I now cannot get it to recognise the AVRisp any more.  I get the following error in both Arduino IDE and VM:

avrdude: usbdev_open(): Found [unnamed product], serno: [unknown]
avrdude: usbdev_open(): USB device has no configuration
avrdude: usbdev_open(): did not find any USB device "usb"

The correct programmer is selected.  I have reinstalled drivers,  rebooted,  tried changing USB port etc etc but I still get the same error.

The driver is showing as working  (libusb-win32 devices) but it doesnt seem to connect to the AVRisp.   

If I change the USB port then it always installs the Jungo driver.

If I use the Jungo Driver and try to connect via 'device programming' in Atmel Studio it also wont connect.  (This worked fine when I first plugged it in)

I am beginning to think that my AVRISP is bricked.   

Any suggestions?

Hi,

Sorry to hear about all this. I think there might be more experienced people to ask in the Arduino.cc forum.

Personally I have had a single avrisp mkII for a long time without problem so that does not really count as have experience.

Did you try letting the jungo drivers install then click on the "Remove" driver option on the mkisp in Device Manager allowing windows to permanently delete the driver. Then run the win32 lib usb.

I hope you don't mind that I have split your programmer discussions into new threads. 

The system auto generates an "off topic" link but your discussions were not off-topic. It makes life easier for other users by keeping each new issue in a new thread. It also reduces unwanted forum notifications to other members.

The "off-topic" info links in the other posts will be removed in a  few days

Thanks

Yes I tried that.   It's just odd that it suddenly stops working when it was OK.

I can't return the AVRisp till Monday so my plan is to attempt a clean installation of Arduino in a virtual PC so I can check whether the problem is due to driver conflicts.  I may also try a manual firmware update on the AVRisp although I havent yet found the tool to do that (it's meant to be in Visual Studio Tools although I cant find it in my version).

I will report back on my progress.

PS no problems with moving my post - thanks

This is most bizarre.

Firstly I plugged the AVRisp into my Macbook and tried it with the Arduino IDE on that.  Amazingly it worked fine.

I then plugged it back into my PC and guess what? - It works perfectly.   The only thing that wont work is burning the bootloader but that is less important as I can use another device to do that.  It gives an error 'USB' not found

Anyway I now know my AVRisp is working OK.  It must have been a driver issue of some sort.  I wont fiddle now for fear of breaking it again.

Don't you just love computers  Undecided

Thanks for the update that is good news. The bootloader burn issue is a known problem in the last release and fix in the next (due next few weeks)

The bootloader burn doesn't work in Arduino IDE either.  It works with USBASP but not AVRISP so I'm not sure whats going on.

Thanks for all your help.

It works with avrisp mkII in the Arduino Ide for me. Did you select the right board? Which board are you using?

By the way I noticed a bug with avrdude (affects both vm and Arduino). After I upload using avrisp I can't then upload to the board using normal serial/usb unless I burn a new boot loader.

Isnt that because the uploaded sketch overwrites the bootloader?  I thought that was how it was meant to work.  Thats the main reason why I want to use a programmer as the sketch starts up quicker and also doesnt use as much memory

After much more hair tearing and trial and error I have finally got a stable development system working to upload via AVRisp programmer and debug via serial.

1)   AVRisp was proving very unreliable and kept locking up requiring a complete restart of AS and often reboot of the PC.   I finally tracked this down to my USB 3 hub.  If I plug the programmer into a separate USB 2 port on the PC it works perfectly and hasnt failed now for some time.

2)  The serial debugging was also unreliable,  often giving 'failed to open port' errors.  However, as soon as I moved my programmer to a separate USB port the serial port worked every time.   My serial link is still plugged into the hub which gives me the benefit of a better power supply.

3)  The well known USB auto-reset problem was fixed by using an FTDI converter board connected to pins 0 and 1 with no reset connection.

It's been a frustrating couple of weeks but now I can get down to some coding at last.

I hope this may help others who may run up against the same problems

Great post thanks. Yes this will be very useful for advanced users who want to use hadware programmer and dump the bootloader.

The FTDI workaround to prevent auto-reset is possibly the cleanest idea but here is some info for you or others just in case.

If the auto-reset is a problem when serial starts then you will see on the serial monitor a Dtr checkbox. Sometimes the window needs to be made wider to see this checkbox. The setting of the checkbox is saved between sessions and when OFF will prevent the auto-reset.

The debugger will override this setting unless you set "Startup Delay/Dtr" = False in the Visual Micro project properties. The default is True otherwise the debugger can miss breakpoint notifications from early in the Arduino startup such as in the setup().

Thanks again for the info and best of luck
