USBASP driver for Windows 7 and Windows Vista x64

24-May-2011 9:24pm

Until now, the USBASP windows driver wasn’t signed. On older versions of windows this was’t too much of a problem as you could override the signature error. On Windows Vista x64 and Windows 7, it is almost a show stopper.

Various methods have been suggested including a utility called Driver Signature Enforcement Overrider or Pressing F8 at boot time and selecting Disable Driver Signature Enforcement. These approaches were far from ideal.

With the release of libusb-win32 version 1.2.4.0 this is a thing of the past. A new USBASP driver is now available; is based on the libusb-win32 driver; and supports 32 and 64 bit windows. It is partially signed which means windows still produces a warning during installation, but that warning does not prevent installation of the driver.

OK, now for the installation procedure…

Download the driver from http://www.protostack.com/download/USBasp-win-driver-x86-x64-ia64-v1.2.4.zip and unzip it
For those having issues with the zip file, please try the following rar file http://www.protostack.com/download/USBasp-win-driver-x86-x64-ia64-v1.2.4.rar
Insert the USBASP into your USB port
The system will attempt to install a driver from Windows Update
and will fail
At this point, go into device manager and find the entry for the USBASP programmer. It should be displayed with a yellow alert icon next to it.
Right click on the device and select “Update Driver Software”
When prompted “How do you want to search for driver software”, select “Browse my computer for driver software”
Select the folder where you unzipped the driver files then click “Next”
At this point, windows will give you a nice red warning dialog with the message “Windows can’t verify the publisher of this driver software”.
Click “Install this driver software anyway” and the driver will install.

What are you using to unzip the file? What is the filesize in bytes? If you clear your cache and download it again, do you have better luck?

Depends on what browser you are using. Also, what are you using to to unzip the file?

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 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.

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.

Protostack have replaced my usbasp free of charge and without me even asking. It turned up in the post the other day. Much appreciated and good work for doing this off your own bat. regards…ab

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.

Hi Albert, did you ever get this problem resolved?. I’m trying everything but I’m still not able to mount the unsigned driver on my windows 7 operating system. Please let me know. And thanks for the time it takes, I’m sure you have better things to do.

I have a serious problem. I use win 7 professional. I installed the usbasp drivers and windows recognize the device. I also use bascom-avr for programming Atmel chips. When I try to programm the chip there comes an error” chip differs at bytes address :00000”. My usbasp programmer works perfect on another pc with windows xp.
Do you have any suggestion ??

Thanks in advance

For those who re having a problem with download they can check out this link:

This is quite irritating.
Why don’t the protostack guys overhaul this post. Just correct the Link internally or post multiple links. I mean nobody wants to waste time over bad links

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

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?

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/index.php?main_page=contact_us) and I will work through the problem with you.

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?

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.

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!

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?
