Under Win 7 / 64 Device Manager recognises under Other Devices a device ProMicro 5V but the driver is no good.
Strange, but I could not find on the SparkFun site a link to the driver.
Googling, I found at following site http://www.mindkits.co.nz/store/arduino-compatible/pro-micro-5v-16mhz-1
has what appears to be a driver "SparkFun ProMicro.inf" which is accompanied by a readme file.
This driver file will not install from Device Manager although I browse and point directly to the folder.
Is there a problem with this driver?
