Revenge of Windows 7Not that simple, alas.
I attached my USBTiny to my Windows laptop. It runs Windows 7, which refuses to load unsigned drivers without some fairly vigorous persuasion. Even when persuaded, it would not load the driver for the USBTiny. I think the driver may not not compatible with my laptop's 64-bit AMD processor. After an hour of unsuccessful experimentation I decided to try something else.
My next two attempts also failed. I can drive the USBTiny using avrdude on one of my Linux servers, but I can't install the latest Arduino IDE on that machine. The server is is running Ubuntu Hardy Heron, and I can't upgrade it easily. Its main job is to act as VMware host to a bevy of virtual servers, and VMware server currently needs patching before it will run on Karmic. I'd have to coax avrdude into some tricky fuse setting; it's easy to brick a chip if you get that wrong. I decided not to try.
Next I tried to use one of the virtual servers. It's running Ubuntu Karmic, and the Arduino IDE installs and runs, but it won't recognise the USBTiny. I suspect VMWare's virtual USB drivers are getting in the way.
