I haven’t been able to figure out how the process of installing the USBasp drivers for the USNoobie is supposed to work.
I’m using the instructions on the USNoobie Usage page here: fischl.de/usbasp/. The driver download is a .zip file named usbasp-windriver.2009-02-28.zip, which contains the driver files but no install program. So, I assume I’m supposed to tell Windows to use the drivers in that folder when Windows prompts for a driver.
I’m not clear on what the button sequence is for launching the USNoobie bootloader. The Usage page says “hold down the bootloader-activation button, then press and release the reset button, then release the bootloader-activation button”, but the video on that page says: press and hold reset, press and hold bootloader, release reset, release bootloader.
I’ve tried both of these, but in either case Windows displays a “USB device not recognized error”, without any reference to usbasp, and without giving an option to provide a driver. Device Manager lists it under “Universal Serial Bus controllers” as “Unknown Device”. I tried updating the device driver from there, but when I selected the folder I unzipped earlier, it displays “Windows has determined the driver software for your device is up to date” message. (Actually, it displays that message no matter what folder I select, so I don’t think Windows has a clue what kind of device it is).
I’m using Windows 7 x32.
I’ve installed lots of USB drivers over the years, and the “Unknown Device” thing usually means a hardware problem. I’m not sure if the problem in this case is something that went wrong with the build, or I’m just not triggering the bootloader. The hardware seems OK - I followed the instructions for testing continuity and voltage in the assembly instructions (which are excellent, by the way), and those tests worked.
Can anyone tell me if the driver installation is supposed to work differently?
