Which USB Drivers?


I apparently lost my USB Bootloader Driver or the USB Driver during a failed sketch load. At the time I was running a simple blink test from my Rpi2. It worked several times, then I had a glitch during the loading. I have attempted to reload from my Windows 7 and from my Rpi2 without success. I read from several searches that there are several versions of the drivers for the Arduino Leonardo, one from cc and one from org. Neither one appears to work. I have tried to reload by using the reset button on the board and through deleting the drivers. At this point I am lost.

Which drivers should I use? Do you have a recommended method for reloading?

Thanks ahead of time and best regards,

I thought I solved it, but it still did not work. According to the instructions, my Ind I/O uses standard Leonardo Drivers. I was hoping that the support files had those in the folder, but I could not find them. So I still need to be pointed to the correct drivers. Thanks.

The standard Leonardo driver should be in Program Files->arduino-1.0.5-win->drivers After installation you should see a COM port pop-up in the "Tools->Serial Port" menu of the IDE. Then select "Arduino Leonardo" in "Tools->Boards" menu.

Maybe also check if by chance the bootloader didn't get got corrupted... In your Windows device manager can you see any USB device that identifies itself as Arduino Leonardo?

Never mind. I see I need to use the drivers included. Sorry.
