Small touchscreen display 7-10' -> 14-16"

yeah 1024x 600 or 768 is not large enough for axis
check out my thing if you want a small screen axis and report any bugs . ive been using it for a while and i havent seen anything unsafe

Okay, I'm going to ask on a long shot.......

At the moment I have a RapberryPi4 with Axis installed and it's displaying just fine on an Amazon special 15" touchscreen. Resolution is set to 1024x768.

The problem is that pretty much all the new touchscreens on Amazon use USB-C as the preferred communication link for video, audio and touchscreen data. However they also have a HDMI port and that seems to work just fine for the video (I'm totally happy with the resolution/clarity etc). They also claim if using the HDMI port for video that you need to use a USB-C port for the touch data. Pi had 4xUSB-A ports, however according to this video....
The guy claims that If you power the Pi via the expansion connector instead of the regular power connector that happens to be a USB-C you can then use that USB-C port for data transfer. So I tried it and still no touch feature. I'm guessing Linux is unaware of this USB-C port and with it connected to the touchscreen it is not visible when I look at the devices  under Mouse and Touchpad in settings (I do see the mouse and keypad I have connected to the USB-A ports) as well as the the two hdmi ports.

To try and gain some insight to that port I swapped out the LinuxCNC SD and instead ran the Pi OS, and lsusb yields:
 

So it looks like the Pi OS can see that port, (Bus 002 Device 001)
Any chance I can somehow enable that USB-C port in LinuxCNC, to allow getting the touch data back to LinuxCNC?

Out of curiosity, how much is a RPI and a good touchscreen these days?
Wondering as i got a Lenovo X1 Carbon Yoga for 120 and a Lenovo Yoga Y370 for 220, bot work for LinuxCNC with Mesa, both have 120Hz touchscreens, very high quality ones, very good keyboards, and both do over 4-6 hours on batteries.
 

I found a decent looking 15.6" Yoga on eBay for $100, so it's on its way. Should be more capable than the Pi and IBM stuff seems to work forever. I will post results when it shows up.

Does it have an RJ45?
Supposing it does not as none of mine have it, so get an USB to RJ45/LAN adapter, around 7 to 15$.
I have 6 of those adapters from very old 10MBit to new 1GBit ones and all work perfectly fine with Mesa.
And i have a Dock for the Y370 with all the bells and whistles, got it for 30 Euro used!

 

From some quick Google research, I think your Y370 is likely Gen2 (2017), while mine is Gen1 (2016), hopefully that won't be a problem, conflicting information about USB ports on the Gen 1, not sure if it has the fast USB-C port, I think not appears to be , 2x USB3.0 and one USB2.0.
USB3.0 is pretty fast, so will probably be okay if I get a decent Ethernet dongle.

Would like to see your USB to Ethernet dongle, I don't want that to be a bottleneck for the MESA card.

Thanks for the images. I'm encouraged to see some have the low data rate type A interface, so it appears the data requirements to the MESA card are not super demanding. USB data throughput has really evolved from the original 1.0 (12Mb/s) to 3.3 (20Gb/s) or 1600x faster. From what I have read 95% of the cheap so called "fast" 3.2 cables don't even have the conductors for the fast laneways so the port reverts back to the lower original slow laneway and the non technical people wonder why the device doesn't seems all that much faster?

I found an original IBM Thinkpad "OnePort" docking station on eBay for $10. In addition to the Ethernet port it has 2x USB 3.0 ports (5Gb/s) so the "OnePort" interface must be pretty capable, that "OnePort" docking station interface was replaced with a USB 3.x port the following year.
