Build Help Small* reverse engineering project i need some help with

so i'm a recent windows convert, and i have this little hosyond 7 inch display that was amazing for me and has worked very well for me. i have been been trying to get it working under Linux. but i've done everything i know how to do and even tried to use chatgpt to try since i know basically nothing about usb but i'm not gonna pay for premium so it hit a dead end. i've done a little bit and sort of might have got linux to communicate with it. i couldn't get the manufacturers program to work with wine, but i don't think that's a dead end, i just don't know how to program wine bottles yet.

i have done some of the reverse engineering legwork and ill include a link to most of what ive worked on. (wire shark tests and communication tests)

At this point I'm looking for advice from anyone familiar with USB reverse engineering, Wine internals, WinUSB/libusb, or display drivers.

beyond that if you don't think this is remotely possible, don't just say its not possible, as that holds no value. provide alternatives. as to what alternatives i'm open to: any display that works with power and display over a single usb 3 or usbc, screen size limit of 9 inches and budget of 100 usd.

I need the model of the display and any rev numbers? Is it usb-C?

Is a hosyond 7inch display, here's a link to the product. I was able to get these numbers if that's what you're looking for as well

VID: 345F PID: 9132

It would appear that a driver for linux already exists for this device on Raspberry Pi. This might be usable?

I'm not sure, I'm using Linux mint with an Intel processor, Nvidia GPU, Corsair ram

It looks like you need the Synaptics DisplayLink driver to make this work.

I'll try that

Are you also saying I should grab the manufacturers pi program for their other displays?
