I’m not able to update my brand new OpenSprinkler v2.1s. When I plug it into my Windows 7 machine, it shows up as “Unknown Device”, not USBasp, and Windows does not find a compatible driver. (I downloaded the USBasp driver, and pointed Windows at the directory, and no dice.)
When I plug it into my linux machine and run lsusb, the device doesn’t show up at all.
Is there anything else to try?
