[BugReport] Ducky missing characters


Recommended Posts

System: MacBook Air 2011 1.6Ghz i5 4GB RAM Mac OS X 10.8

Ducky: White board (ducky-decode duckv2 flashed) & Green Board (out of box)

Memcard: Samsung 4gb Class 4, PNY 4gb Class 4, SanDisk 4gb Class 4, Included 256MB

Encoder: ducky-decode v2

Ducky is "skipping" keystrokes randomly on my machine. I've tried all the hardware above and while it seems the problem has lessened over time and the more I test it's still not going away.

It's easier to show than explain; this is the worst result I had, which was my brand new ducky with the included card. Newer runs have been a lot better but I have not been able to get a flawless run out of it yet.

We are aware, its a matter of getting the balance right. It types so fast it sometimes/rarely skips characters.

I've tweaked the current speed on the v2 firmware where I felt the balance was right, as the Ducky works best when it types fast, rather than typing at the speed of a human.

With the payloads, its about splitting up large strings (not always best) and using delays

How does your test-code fair if you insert "DELAY 50" or "DELAY 100" inbetween CMD CONTROL f, STRING X and the ENTER statements?

The extra DELAYS will hopefully give the HID buffer time to catch up.
