Hello,

I am a regular user of Avrdude and USBasp from http://www.fischl.de/usbasp/.

It was working great till the WinAVR-20071221.
I recently installed the WinAVR-20080512 version and it has stoped detecting the USBasp device.
It says :

Code:

avrdude: error: could not find USB device "USBasp" with vid=0x16c0 pid=0x5dc

I am not sure what is the problem here. When I revert back to the older WinAVR version every thing works fine.

Kindly help me to resolve this issue.

Hello,

Did you check by rolling back to the older version. Since mine started working as I did it. I am managing with the older version of WinAVR for now.
Lets hope that some one would answer this query.

Hello!

This is caused by libusb (libusb0.dll since version 0.1.12.0). Use Version 0.1.10.1 instead.

I too suffered the avrdude failure with my usbasp after upgrading from WinAVR-20071221 to WinAVR-20080512.

My 'work-round' is simply to rename 'avrdude.exe' in WinAVR-20080512 to 'avrdude_doesntwork.exe'.

This just means that the path environment variable is traversed a little further before avrdude.exe is found (in the previous installation directory).

Or just update the windows driver for USBasp. Download here:
http://www.ulrichradig.de/site/forum/vi ... 3792#p3792

The problem was, that the dirver version 0.1.10.1 is not compatible to the libusb DLL version 0.1.12.1 in WinAVR 20080512.

Hello,

The new driver given in the Link by thomasATulrichradigDE did work.
I am now able to make connection to my USBasp.

Additional feature is that a Safe unmount is available for the USBasp like some Pro' devices.

Thanks for the generous help.
