If you change it in libusboop, you need to change it accordingly in libusb.pas. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Thanks for the link to the tutorial, I'll have to look into that! I have kind of a mess of things that runs through this whole sequential list checking all these different timings to see what needs to be done.. if all the things that required different timings were each in their own thread it would simplify things greatly James -Original Message- From: fpc-pascal On Behalf Of Jean SUZINEAU Sent: Friday, August 16, 2019 1:34 PM To: fpc-pascal@lists.freepascal.org Subject: Re: [fpc-pascal] *** SPAM *** Re: USB Human Interface Devices Le 16/08/2019 à 17:11, James Richters a écrit : > Can I even do threads in a console program?

By writing a descendant of TThread it's relatively easy to write a thread in FreePascal ( https://wiki.freepascal.org/Multithreaded_Application_Tutorial ). From your (non main) thread you can execute a procedure in the main thread by calling TThread.Synchronize. From what I remember, the main problem in console is that you need to call regularly CheckSynchronize() ( from unit Classes ) from your program which run the main thread. That will be simpler for you, in my case, I had to export from my dll a pascal function calling CheckSynchronize() and call it regularly from the 4gl program with a timer ... As far as I remember, it works just with a queue, when you call Synchronize you add a function call to the queue, and CheckSynchronize() read the queue and do the actual call of your function. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

> Did you try to change your driver with Zadig (https://zadig.akeo.ie/) for > your device 10CE:EB93 ? No, I didn't try that.. but I'm trying it now I downloaded Zadig, and used the pulldown and selected devices until I got the one with the USB ID I want. It filled in as follows: "USB Input Device" Driver: HidUSB (v10.0.17763.1) USB ID: 10CE EB93 WCID has a red X in it I am not sure what to do from here. It looks like it has a driver for HidUSB and maybe that's what I want because the project at https://github.com/prof7bit/HIDAPI.pas has the same functions as the ones I am looking to duplicate... but then I don't know, maybe I am mixing up terminology Anyway, before I go changing drivers.. is there some way to un-do this change? I don't see HidUSB in the list of drivers that Zadig can install, so if it turns out hat I really wanted HidUSB driver and I changed it to LibUsb then is there a way to put it back?
