Not sure if polling too often is causing the issue, but it could be assigning a value directly to a parameter too often might be the issue. Maybe sending the info to chops would resolve this issue. Definitely need to test this.

BTW, did you notice one of the comments on this video mentioned my site? Very cool!

following up on what Mr. Bleh pointed out, have you tried to get the data into CHOPs first and then reference from there? is that stable? can you have 2 Mouse CHOPs?

are you able to get any info on why it’s crashing? can you spit out a text file or echo to the console before assigning values to params? you’d have to figure out how to launch H from the cmd line in Windows. cygwin?

does your method allow you to test other devices like a mouse? does it crash? can you incorporate that HID stuff? what about pygame?

first i thought you were getting bad data, but now i’m thinking that maybe depending on context you’re polling too often and not allowing H to do other tasks. possible? just guessing here.

if i sit starring at this text any longer i’ll come up w/ completely opposite ideas… like maybe the polling process is too slow for the param to use it? hopefully fixed by going to CHOPs first, yes?

whatever it is, you must be really really close. you just need to find the invisible door. ;o)

on a related note i thought you might find this interesting, someone took a Wii-mote and wired the sensor into their pc and they are using it to modify parameters to drive a car around inside the Houdini viewport:

pretty cool actually, and kinda related to what you are trying to do, so i though i would share
