Trying to figured out the LED RGB bits #23

So I've had a portal laying around doing nothing for forever now and decided to mess with it. No Skylanders to scan but hey there's an RGB LED!

After digging around I noticed this project and https://github.com/capull0/SkyDumper both use the portalio.cpp code for setting color. I noticed it was sending the C command and the three subsequent RGB values to the device via the hidapi. Not being very (or at all) skilled in C++, I set out to implement the color code externally.

I'm still working on getting something going with Python + PyUSB but still a ways off.

I did however do a little usbmon sniffing in wireshark to see what exactly Sky{Reader,Dumper} was doing to set the color. I noticed it sends the R (reset) and A (activate) commands before sending the C + 3 byte RGB. Where I'm at now is that AFTER I have used the portalio code once to set the color, I can then do it manually via usbtool. 

sudo usbtool -v 0x1430 -p 0x0150 -d 0x43,0xFF,0xFF,0xFF control out 0x1 0x01 9 0x0200 0

The control variables were ascertained out of the wireshark dump I ran. I have been unlucky in trying to send the R and A beforehand, so my current method of starting control is running the dumper tool once just so it initializes it.

I guess my question after all of this is: Any tips on trying to send the R and A myself? Ultimately my goal is to implement all this in the aforementioned Pyhton + PyUSB. (I've tried the R and A both in PyUSB and usbtool but have come up short for solutions)

sorry for the very late reply, are you able to wireshark sniff you python code and see what python is sending differently from the working command?

Oh jeeze. I don't even know if I have that portal anymore. I guess I'll just close it. If I find it again I may come back to it.

Thanks
