Only USB device I can think of that work on an ADB Macintosh is the AlphaSmart 3000, via special adapter cable

Techknight: I think bbraun was trying to make an adapter that would allow, at least, for one to use USB keyboards/mice with an ADB Mac. I don't remember if he was successful or not, although he did come up with a nice USB to ADB + 128k/512k/Plus adapter.

I have a working ADB to USB adapter. But I don't think that USB to ADB exist.

A cable adapter won't do jack, if you'll pardon the pun.  You're talking about two very different data streams: USB would have to be intelligently translated by a microcontroller to ADB, and you need a micro that can be a USB host, not a device.

This is something I've been considering making. There's a software USB library for AVR microcontrollers called LUFA, that supports both USB device and host modes, so the microcontroller wouldn't necessarily need hardware support for USB host (though it would be nice). bbraun also did some work on this idea a year or two ago, and got something that mostly worked, so it's definitely possible.

One of the Kensington Mouse-in-a-box (64475) is a USB laser mouse and it comes with an ADB attachment. I have never used it but I gather from other fora that the USB>ADB attachment is specific to this mouse.

Amazon have one at the moment but I'm not going to lavish $50 + postage to find out about it.

I have a Kensington TurboMouse USB/ADB trackball. The function is right in the name. I lost the USB adapter ages ago, though, because I only use it on ADB machines.

So it is an ADB device with an ADB>USB adapter?

I have an ADB Turbo Mouse trackball and it is a nice device. I use it attached to by KVM as my main mouse.

The TurboMouse USB/ADB has a cable attached with a male mini-din plug attached. It has a non-standard pin layout. One each adapter cable from this to ADB and USB are included. I believe the unit has separate ADB and USB controllers inside, using different pins on the mini-din for each.
