I have just found the time to try the USB mouse adapter I got in November last year from @talrek for the first time, so far I none of my mice worked. I guess I need to purchase a PS2 compatible one, as suggested in this thread? Btw, the LED never shows any sign of activity.

Would this one work? It has USB / PS2 dongle included, so it should be PS/2 compatible protocol:

Have ordered it to see if this fixes my problem.

Taken from here: http://www.cpcwiki.eu/index.php/PS2Mouse#Using_The_Mouse_Adapter


"When the power is applied, the PIC will try to recognise and initialise the mouse. If recognition and initialisation is successful, the LED will blink once for approximately one second. After this any movement of the mouse will make the LED blink. If the mouse fails to initialise (there may be incompatible ones out there or it may just be broken) the LED will flash continuously in one second intervals."

So to answer your question. If the LED never does anything, then it's either not getting power or the device is broken. An incompatible mouse will cause the LED to flash permanently. So don't buy a new mouse until the device is working.

Thanks Bryce. I guess I'll return it to @talrek  then...

Hi,
I just read all the messages.
Of course you can send it back to me. I will replace it.

Bryce, are you sure ? because I tried some mice and there are some which don’t work and the led doesn’t blink... I never had the case it blinks permanently.

Anyway, let me know if you want me to send you another one just now, or if you want me to test yours before sending a new one ! [emoji6]

Cheers.

That's good news... that it does not have to blink at all.
Let's wait for my new mouse to arrive, maybe it will just work!


Thanks both so far
Michael

I have 3 different types and only one of them works.
The LED does not light up or blink with the two that does not work
(Logitech B110 and a cheap China model IK83636 - Plexgear).


The one that works is also a cheap China model HM5211

There's only one situation where that could happen and I'm suprised it can. The firmware (at least the original one from me, not sure if that's what Talrek uses) sends a reset and then the initialisation commands. It waits after each command for the mouse to acknowledge. If no answer or an incompatible answer comes back the LED will flash permanently. The only time it won't flash an error is if the reset command wasn't replied to (otherwise it would flash all the time when no mouse is connected). As far as the PS/2 and USB HID specs are concerned all mice should use and acknowledge the reset command, which would make the no-blink situation impossible. So obviously these mice have completely ignored the specs and aren't replying to anything, so the mouse adapter thinks that no mouse is connected.

OK, the new mouse arrived and now it works like a charme!No need for further replacement / exchange action. Thanks for offering.
So, with the wrong mouse attached, you indeed see no LED activity at all.
With a supported mouse, each movement and mouse button click (and even scroll wheel) causes LED blinking.

FutureOS works fine, but with the drawback that this is an AMX mouse and hence, it behaves more like a Joystick than a "real" mouse. But better than a joystick and no mouse in any case!

Ok, good to know. The blinking with each movement is correct, that's how it's meant to function, but obviously the error trapping is missing some situations?

It seems so. For the next revision I would suggest to improve error handler or at least have some initial blinking upon start such that people know its not dead. Because that's how it occured to me with no sign of activity whatsoever with wrong mouse.

Eh, it's a 9 year old project that I no longer build. I wasn't planning on a next version unless people want some new device with more features.
