For some time now, those wanting to use the Adafruit Industries USBTinyISP<\/a> with the 64-bit versions of Windows 7 or Vista were faced with the following errors when attempting to install the device drivers<\/a> supplied by Adafruit:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

For some reason, the 32-bit versions of these operating systems don’t prevent the unsigned drivers from being installed, although they do complain.<\/p>\n

There are a few\u00a0workarounds<\/a> that involve hacking Windows or disabling digital signature checking,\u00a0but thanks to a tip by user wayneft<\/a> on the Adafruit support forums, I was able to make the process much more straightforward.<\/p>\n

The USBTiny drivers are based on\u00a0libusb-win32<\/a>. \u00a0Based on some notes I found on the libusb-win32 wiki<\/a>, I discovered that the latest libusb drivers contain a proper digital signature:<\/p>\n

Vista\/7 64 bit are supported from version 1.2.0.0 since a Microsoft KMCS accepted digital signature is embedded in the kernel driver libusb0.sys. libusb-win32 based device drivers can also be submitted for Microsoft WHQL testing. Several companies have successfully finished the WHQL testing with their libusb-win32 based driver package. This will allow the customers to install the driver without a warning under current 32bit\/64bit Windows.<\/p><\/blockquote>\n

This is good news!<\/p>\n

I downloaded the latest\u00a0version of libusb-win32 (1.2.1.0) and used the included inf-wizard tool to create new drivers for the USBTinyISP:<\/p>\n

usbtinyisp_libusb-win32_1.2.1.0<\/a><\/p>\n

I used the Windows device manager to upgrade the broken drivers on my Windows 7 64-bit machine. \u00a0There is still a warning that “Windows can’t verify the publisher of this driver software” but there are no more errors about digital signatures and the new drivers appear to install and work correctly.<\/p>\n

I haven’t done a huge amount of testing with the drivers, but I was able to communicate with the USBTiny via avrdude and flash a simple program to an AVR. \u00a0 I also haven’t tested this fix on Vista, as I don’t have access to a computer running it. \u00a0If anyone tests these drivers on Vista x64, please post your results in the comments!<\/p>\n","protected":false},"excerpt":{"rendered":"
