Check the Windows O.S version for selecting a correct driver from Champtek support download website: -x86(32bit): -x64(64bit): 2. After the driver installed, connect the scanner to the USB port on PC.
Latest download for STM32 Virtual COM Port driver. Improve your pc peformance with this new update.
Go to Device Manager: in the Start menu Search box, type 'device manager' and then press enter 4. The scanner will be automatically found and self-installed as a 'STMicroelectronic Virtaul COM Port', the port number could be varied, according to the USB physical port on the PC.
Check the values: USB VID_0483 & PID_5740.
I've been trying to diagnose my problems for the past 4 days now. It started with me trying to install the driver manually using a software. It would install successfully but it would not display in Device Manager under Ports. I found out I can manually install the COM port using Add/Remove hardware (typing hdwwiz in start menu search area).
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.
This is a virtual port so I am not sure how to get this to work. 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. I even tried doing both at the same time. 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 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 believe that's the solution but I don't know how to gain access. Did 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 don't understand how to open these types of files or where they are located on the computer.
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.
Unfortunately due to fact I have no knowledge in C++ programming or even programming in general, this is probably as far as I will get for now. I don't know how to proceed from here and I'm sure this is not something I should not be dealing with at the current moment. I greatly appreciate the help. -------------------- It seems I was taking the wrong approach to fixing the problem. I have the driver installed and it still doesn't show up under Ports in Device Manager. Would you have any idea how I can even begin diagnosing the problem?
