roccat vulcan tkl pro - Githubissues

cbastienbaron commented 3 years ago

Hi,

my keyboard (https://fr.roccat.org/Support/Product/Vulcan-TKL-Pro) not appears to be recognized :(

output lsusb : Bus 001 Device 036: ID 1e7d:311a ROCCAT

have you got a clue ?

@cbastienbaron Hi, I believe it is not enough to simply change the supported USB IDs, since you have the TKL variant of the keyboard with a different number of keys. This would require some more invasive changes to the source code. Do you know whether the Vulcan TKL Pro uses the same initialization sequence and HID reports as the Vulcan 100/110/120 series keyboards?

HI @X3n0m0rph59 , thanks for your response, i understand consequence, no pbl :)

don't know if tkl use ther same init seq, where i can found this information ?

@cbastienbaron To enable support for your ROCCAT Vulcan TKL Pro device we basically need a dump of the initialization sequence as done by the Swarm software running on Windows 10 (or in a Windows 10 VM). This can be done by using Wireshark to record the traffic happening on the USB bus.

With this information we can implement the code needed to enable LED support.

I wrote a short wiki article about this here: (Please note, that this is written for a different project that also aims to implement LED support for keyboards) https://github.com/X3n0m0rph59/eruption/wiki

So you basically would need to perform these steps:

Load usbmon Linux kernel module: sudo modprobe usbmon
Start Wireshark recording on the usbmon interface that corresponds to the USB bus that your keyboard is connected to
In a Windows 10 VM: Bind your keyboard USB device to the VM, ROCCAT Swarm will then initialize the device (to AIMO mode)
Stop Wireshark recording and save as *.pcapng file
