I have been having this issue where I’m trying to get this tester to work at my company, we are using FTDI chip C232HD-DDHSP-0 cables and the old cable works just fine with no issues however the new cable we just received that is the same exact model won’t work with our tester program. For reference we do modify our cables in house by adding a resistor to them and we only use the the yellow, orange and black connectors with a split off connector with the resistor (this is for grounding from what I have been told) but the cables have been modified in the same way so I’m really stumped here. I thought it was an issue with the D2XX drivers however I updated them and no change. If anyone has any ideas on what I could do that would be great as I’m really stumped here.
TLDR: Im not sure of what I need or where to start but I want to make a device to plug in USB and make windows think it's an HID touchscreen. If anyone has suggestions on what device to use and what to search as a starting point I would appreciate it. I've tried wording it a bunch of different ways but I usually only manage to bring up search results for touchscreens made for devices not what I'm actually trying to do. If it helps I'll explain my purpose below.
More Context: I'm remaking a bunch of kiosk style devices at work and they only serve one purpose and don't really need an expensive touchscreen on them since there is minimal text input. Mostly they can be navigated with a mouse. There are a few things that still need text input and we are trying to not have keyboards attached to every single station. Since these are almost all bare bones OS and are public facing we remove a lot of things (explorer, start menu, etc.) we had these working fine with windows 7 to where on the few occasions that you needed to use a keyboard the osk would open automatically and you could just click the keyboard buttons with the mouse. Windows 10 & 11 however you have to manually open the osk via the shortcut in the taskbar when you need it. It can only be automatic if you have a touchscreen connected, but since the taskbar is removed we can't access the shortcut. So instead of buying all new touchscreens I was going to try to make a device to emulate a connected touchscreen. I assume it would only need to do the USB handshake and tell windows it's a touchscreen and windows could use the generic hid touchscreen drivers. As long as the device is plugged in the osk will come up since there is a "touchscreen" connected and we can just use it with the mouse still. I got this idea after seeing a video about the firefly rp2040 USB host showing the USB info of a connection between windows and a usb device and thought maybe that info could be copied and flashed to another device to do the handshake with windows. Even if I have to buy one touchscreen to use to get the info from, it would be worth it instead of buying all new screens.
Any information would be helpful! Even just proper search terms to use on Google, or to tell me not do do this and why it won't work.
