(Bear with this complete newbie in programming uC.) I received AVR XPLAIN (the original) evaluation kit, installed AVR Studio 5 on a Windows 7 machine, powered up the board with a USB cable connected to the same Windows box. All appear functional except Windows won't enumerate the USB device. It recognises it as Xplain USB Gateway but has no way of installing a driver for it.
I downloaded several versions of AVR drivers including http://www.atmel.com/dyn/resourc... that has this description: "(2 KB, revision A, updated 5/11) The driver file supports both 32-bit and 64-bit versions of WindowsÂ® XP and Windows 7," as well as http://www.atmel.com/dyn/resourc..., http://www.atmel.com/dyn/resourc..., etc. Windows 7 doesn't know how to install it nor can it "update driver" using these files. Inside AVR Studio 5, it only recognises simulator as available tool.
Then I loaded the boot loader by jumping pins 1 and 2 of the JTAG USB header. One driver specifically said to work with Win7, https://www.avrfreaks.net/modules..., does allow Win7 to see the device as AT90USB128, but AVR Studio 5 still don't see any new interface.
Beginner guides I can find mostly talk about Studio 4 and JTAG tools, with little mentioning of USB gateway installation. (Most stop at WinXP, too.) Google led me to https://www.avrfreaks.net/index.p... but I can't seem to make full sense. (For example, one post says 'the "official" driver is just a wrapper that uses the Microsoft CDC driver for the board, so any existing CDC INF will work once you've changed the VID and PID.' Now does Win7 come with a CDC driver? Another post says "you have to load the xplain-bc.hex into the USB controller and not the one in the display-demo chapter." How do I do that?)
MacOS X thinks the preloaded firmware presents a dial-up network service called "Xplain USB Gateay" and pretends to dial out if I allow it to; if I enable the boot loader, OS X would no longer see it in network devices. Either way, it can do nothing about it.
At this point, my first objective is to get to see the virtual COM port that the USB gateway is supposed to expose. The second objective is to load compiled code from Studio 5. Do I need another tool to do any of these?
