3Mbps doesn't work with MX-12 servo #2

Hi @horchler, I'm still using your nice DynamixelQ library but I just realized that my MX-12 servos didn't work when baud rate was set to 3Mbps although they should be able to support communication up to 4.5Mbps according to their data sheet.

Is there something special I would need to tweak ?

Thanks for your feedback,

Hi. This is an MX-12W, right? I don't have one of these so I've never explicitly tested it. What do you mean by "doesn't work"? Does it not communicate at all (e.g., return it's model number or firmware version) or just not move in response to commands? What mode are you trying to operate this in? Does it work fine at lower baud rates? How are you configuring the baud rate on the servo? Have you updated the servo's firmware?
