  “avrdude -p atmega16 -P usb -c usbasp -U flash:w:Blink.hex”

  it gives error as

  “avrdude: error:could not find usb device ‘usbasp’ with vid=0x16c0 pid=0x5dc”.

  I have a Windows 8 computer and I cannot get it to update the driver for the USBasp programmer. I tried starting up while holding F8 and also downloaded overrider software. No success.

    I couldnt get the driver running on windows 7. It was reported as having known issues.
    The best solution I found was to use Oracle VMWare to run a virtual version of Windows XP. You can direct the USB device to the virtual machine. You will need an older version of the Java Runtime - 1.6 is best. The latest versions of java wont work on XP. Once I went through all that , the programming went like a dream.

  You download the software Easy Driver Pack for Win8 x64 at download here (Chinese version), after downloading, run the .exe file. For other Windows versions, you accessed at http://storesofts.wordpress.com/ and search by keyword Easy Driver Pack

  Hello, I am having the same problem. My Win 7 64bit Home Premium recognises the programmer as USBASP, then the driver instalation fails (so far so good). But then, when I try to install it manually, after I select the driver folder and click next the installer says it couldn't find the driver. I have tried the drivers from your zip and also the drivers from fischl.de, but nothing works. Can you help me?

- semikonductor • 3 years ago

  Hello,

  I installed the drivers on the netbook as soon as it was recognized. Now each time I connect the ASP, it is recognized. It's working like a charm. This is weird but I guess clearing the information of all past USB devices should resolve the issue for anyone. (I connected it on the netbook for the first time before installing the drivers).

  I don't think there is a clash. A software issue maybe!

  In a nutshell, always install the drivers immediately as soon as its recognized to avoid problems.

  Besides, this device is awesome. You should add Atmega 16A to the compatibility list. AVRDUDE treats it like atmega16. Both are however, different devices even though their specs are the same (apart from a little difference in that supply voltage range). Thanks for the help though!

    Appreciate the tip. When did you install the drivers on your PC ?

    see more
- semikonductor • 3 years ago

  The device shows up in device manager as an unknown device. When I first connected it, it was recognized as usbasp. Then this pc did not recognize it. I connected it to my netbook and it was recognized as usbasp. Their is a sofware deview which shows history of all connected deviced. It also shows that a usbasp has been connected. Should I use a hub? Which hub do I need and what exactly would it do?

  see more
  - Daniel Garcia semikonductor • 3 years ago

    The fact that the netbook recognized it suggests that it is not a hardware problem. It also isn't a driver issue.

    Don't use a hub, it is always best to connect directly into your PC.

    One thing to try is disconnect as many USB devices as possible. Boot up with just keyboard and mouse if that is possible, then try inserting the usbasp. Maybe there is some sort of conflict.

    see more
- semikonductor • 3 years ago

  Same problem!

  Windows recognized the device the first time as usbasp but now it refuses to recognize it.

  This is irritating!

  The drivers are available all over the net but this is a hardware issue and if so many people have this, this is supposed to be a manufacturing defect.

  I am on Windows 7 64 bit. Someone said that the problem will be fixed on XP. Should I go on installing XP then?

  - Daniel Garcia semikonductor • 3 years ago

    There are many different reasons why you may be having difficulty with the programmer, manufacturing defect although rare is always a possibility. If you purchased it from us and there is a manufacturing defect, we will be more than happy to send you a new one. I just have a couple of questions first.

    Does the programmer show up in device manager ?
    Are you connecting directly to the PC or via a USB hub ?

    Please contact us via the Contact Us page (http://www.protostack.com/inde... and I will work through the problem with you.

  On a positive note, I downloaded the file, unzipped it fine and installed it with no problems on my laptop running windows 7 64bit. Bascom AVR programs fine using my home made programmer with USBASP.

  Now I'll have to update it on my desktop PC as I did all sorts of things in the registry on that to get the original driver to work :-)

  Thanks for your work

    A lot of people are having trouble with the zip file. I'm thinking it might be a (zip) file compatibility issue. Anyhow I've uploaded a rar file with the driver. Let me know if it helps.

  This problem has been going on for way to long.

  Whenever I download the file it seems to unzip fine. I've tried this from multiple locations. I've also tried creating new zip files and re-uploading it, but with no luck. My theory now is that there is some sort of compatibility problem with the zip file.

  This morning I re-zipped the file and turned off compression. I'm hoping the compatibility issue is in the compression algorithm. Can you please download it and have another go.

  Thanks.

  I can download the driver file OK (270 kb in size), but neither winzip or winrar will unzip it.... winzip says "cannot open file" and winrar says "unexpected end of archive". I am running Windows XP. I hvae cleared the cache and tried again, still no luck.

  Can you please please just post the drivers in unzipped form? This is very frustrating - it seems other people are having the same problem, I don't know how anyone has been able to open the drivers.

  see more
- Anthony Banks • 3 years ago

  First time that I used the new drivers, the usbasp mounted fine, but then due to a dodgy connection (who knows?), it dismounted. After that, it wouldn't recognise the device. It was then that I discovered that by repeatedly plugging/unplugging the usbasp from the computer, it would eventually recognise it. Sometimes it recognised the device in as little as 3 plug/unplug iterations; other times it took 18 or so goes...but...it eventually recognised it. The board itself could be faulty but then it worked so who knows? Persistence paid off though and I was able to upload the code to the chip.

  I also cannot install the new driver, and keep getting unkown device in the usb controller devices, despite updating the drivers in my win7 64bit professionel computer.
