I'm trying to map a usb device to a com port for a wine program. To do that however, I need to find the name and path of the device, which I am having trouble with. I have no devices named ttyUSB, ttyACM or anything like that and I'm unfamiliar with what it would be in Garuda. Also, the system does recognize the device.

Try lsusb command in terminal. Also, post the output here, as text, enclosed in ~~~

Also, what type of device it is? Brand and exact device name and model would be helpful too.

I'm specifically trying to map the HK GK61 keyboard to a com port. Thank you for your response. Still have a lot to learn about linux in general so I appreciate it. I'm not sure if it would even work anyway but knowing this in general would be nice. Thank you!

https://wiki.winehq.org/Wine_User's_Guide#Serial_and_Parallel_Ports

Serial and parallel ports are detected automatically when Wine starts. Windows serial ports follow a naming convention of the word COM followed by a number, such as COM1, COM2, etc. Similarly, parallel ports use LPT followed by a number, such as LPT1. Linux, Mac, and BSD each have their own device naming conventions, but in every case the serial or parallel device is located somewhere in /dev. You can see the mapping of Windows devices to Unix devices by looking in ~/.wine/dosdevices.

You can either test all of these ports, or another smarter approach is first unplug the keyboard and pipe the output to a text file, then plug in the keyboard and pipe the output to a new file and compare the difference between two.
I hope you can now find the right com port.

I have already used grep and monitored the output after reconnecting the keyboard which I should have already stated, my bad. When I look under dosdevices there are 0 comports., and I've manually tested just to make sure. Just the two storage drives. Using the registry editor from wine, I can specifically map the device to a comport which it seems like I'll have to do since it didn't auto detect any.

My issue is that to do that, I need to provide the direct path to the device which is located in /dev, which I cannot find. Monitoring using grep, outputting it to a text file, using any command to get usb info, etc...none of it tells me the path in /dev and there is nothing in there labeled usb anything so I don't even know where to start.

I would...

Unplugged, run lsblk
Plugged, run lsblk

Compare the two.
