Confused about firmware features

[this-is-me]

Ok, so I have some specific questions about the firmwares on the ducky github page.

I am currently running c_duck_v2.1.hex which supports mass storage and hid. I need to know; Does it support key triggers, such as num lock, scroll lock, caps lock?

Also, I tried using a vidpid.bin, and the device didn't report the new values. Does this firmware not support vidpid.bin?
Considering the vidpid.bin and composite firmwares, it seems that I would need three VID/PID combinations: One for the composite device, one for the keyboard and one for the mass storage controller. I would like to use the following values:

Composite:
0936 NuTesla
0030 Composite Device, Mass Storage Device (Flash Drive) and HID

Keyboard:

05ac Apple, Inc.

0202 Keyboard [ALPS]

0b05 ASUSTek Computer, Inc.
1708 Mass Storage Device


However, perhaps I am missing the understanding of the composite vid/pid. Does it work like a USB hub, or is it all-inclusive (meaning you can't change "sub-debvice" vid/pid)?


On another note, what software can I use to compile a firmware from source code on github?

No, it doesn't support key triggers. This is due to the limited space in the firmware.

I believe it does support changing vid/pid, and you only have 1. The ducky doesn't act as a hub, so you can't change sub-type.

Thanks for the information. I suspected as much, but wanted to make sure. Due to this fact, it looks like there will always be a close choice between firmware including mass storage and keyboard indicator features, since it appears there is no one firmware to handle every function.
