Fedora

[jwinarske]

I have a TRX40 Creator running Fedora. I don't see any visual response when using your tool. This is after installing rule that matches device present. Perhaps I need to boot into windows and update the firmware. I was hoping to avoid buying/booting Windows and doing the tracing, but I think I may need to.

In addition to the documented protocol, it would be good to have Wireshark traces for each of the example transactions.

Could you post here the output of lsusb?

Ok, the device is the same.

Please try running as sudo:

sudo asrrgb --mode=off
sudo asrrgb --color=0000ff

This should turn off all leds and then turn on as blue. Firmware upgrading the controller should not be needed, but maybe there is some particularity for your motherboard.
