Need HELP - Arduino Leonardo bricked

Development Tools IDE 1.x
1

Hello everyone,

First post here, so i have a sketch on my leo for a while it was a mouse clicker i was playing around with.

So i haven't touched it in over 6 months, i plugged it in and my computer can not detect the leo. It is the same computer that i was using to make the sketch and mess around with it. So basically i need to detect it so i can use it again.

Any suggestions?

Also, when it gets plugged in, it says USB not recognized

i own a UNO and a LEO, and no programmer, i read online that that you can take another good leo and use a USB programmer and redo it. is that true.

You can use the Uno as a programmer. Do a search.

Have you tried different USB cables as suggested above; there are charge only cables.

Does your board still do what you programmed the last time (mouse clicker)? If not, check / replace the cable.

Before going the programmer route, you can test the following; instructions are for Windows, if you use Mac or Linux you will have to use the equivalent commands for the Windows device manager.

Open Windows device manager.
2)
Press and release the reset button on the Leonardo.
3)
Check in device manager under ports if there is a com port labeled something like "arduino leonardo boot loader".

If not, burning the boot loader might possibly solve the problem.

If the above com port shows
4)
Start the upload of a blank sketch.
5)
When the IDE reports the memory statistics, press and release the reset button.

Let us know how far you get.

Note that the Leonardo only stays in the bootloader for several seconds after pressing the reset button, and double pressing the reset button has no different effect. So you need to have Device Manager open and be looking at it when you press the reset button.

Just curious here , I am a newbie here but was wondering if you tried the loop back procedure? Basically you tie tx to rx and reset to gnd I believe, then you open serial monitor and type anything in it and it should repeat what you typed below .Couldn't hurt, you could find that procedure in the trouble shoot section.
