If they are supposed to be.inf files, where do I find the correct one? Download the libraries the usb_desc.h locate in STM32_USB-FS-Device_Lib_V3.4.0 Project Virtual_COM_Port inc hope this helps, It helped a lot and I finally understand where all this information is.
I don't understand how to open these types of files or where they are located on the computer. I believe that's the solution but I don't know how to gain access.ĭid you try one of the suggested fix from the? I'm trying to figure out how to access the information they're referring to regarding things like changing CDC_IN_FRAME_INTERVAL in usbd_conf.h Or if you used google search and looked at the second link: I want to access usb_desc.h to change VIRTUAL_COM_PORT_DATA_SIZE. I have absolutely no idea how to access the usb descriptor files or where I can find usb_desc.h to change the buffer size. I looked up some information and came to these two links: I believe the error is in the buffer size as people in those two threads stated. I even tried doing both at the same time.
This is how my Device Manager looks: Thanks for the assistance! Did you try the drivers from their website? I tried to manually install the driver as well as using the drivers on their site. This is a virtual port so I am not sure how to get this to work. I do that and it says it installed successfully but it also gave me an error: 'This Device Cannot Start (Code 10).' I looked up possible solutions but the ones I found involved actual hardware. I found out I can manually install the COM port using Add/Remove hardware (typing hdwwiz in start menu search area). It would install successfully but it would not display in Device Manager under Ports. It started with me trying to install the driver manually using a software. I've been trying to diagnose my problems for the past 4 days now.
