Hello,

I recently upgraded my razer_hydra install to the indigo branch, and made sure that the udev rules were properly installed. Now when I run the command:

roslaunch razer_hydra hydra.launch publish_tf:=true

I get the output:

process[razer_hydra_driver-1]: started with pid [8245]
[ INFO] [1405699624.237070758]: Using filter corner frequency of 3.0 Hz

[ INFO] [1405699624.280525075]: starting stream... (first packet takes a few seconds)

and the process hangs there.

Has anyone else had this problem? When I was using the hydro branch, things worked fine.

Thanks! Kel

So I didn't realize that the line of code was removed that said something like "First message recieved, everything should be working now" However, I get nothing from rostopic echo /hydra_joy

Could this be a problem with the udev rules? When I downloaded the source and catkin_made, it did not place the 99-hydra-indigo in my udev folder. I had to do it manually.

Ok, so I blew away my build and devel and catkin_make again. I also switched from the ros fork to you aleeper git, and it works fine. So not sure if it was my environment or something in the hydro-devel branch of the ros fork. Probably my workspace :) Thanks for the help!
