I am running into an odd keyboard problem: some key combinations end up reversed (e.g. "pl" ends up being emitted as "lp") when I'm typing quickly. The problematic ones are the key combos I hit with two adjacent fingers on my right hand-- in other words, the combos I can hit the fastest. No idea how fast is "fastest", but I guess around 50-150 msecs gap between them.
I'm trying to track down whether this represents a failed keyboard, an inherent limitation of my Goldtouch USB keyboards, or a software problem on my Windows 7 Lenovo T500.
I use a PS/2 version of the same Goldtouch keyboard at home with no problems. I've tried another USB keyboard with my laptop and can't repro the problem. I've also used this keyboard on other laptops without a problem.
According to this SU thread, USB keyboards have higher latency than PS/2 keyboards-- up to 30 msecs. I find it hard to imagine that I can type key combos faster than 50 msecs, probably more like 100-150.
Anyone encountered this problem with this or another keyboard? If so, how did you fix it? Any idea if there's a "keyboard log" or some way to diagnose the problem inside Windows?
