I'm happy to announce the v6.7.2 VCP driver that adds Windows 10 support is now available on our website:
This version of the driver supports Windows 7/8/8.1/10.
The driver customization wizard, AN220, has also been updated to support v6.7.2.

I'm very sorry - but this "Driver" is still not working on my Windows 10 computer: installation executes but nothing happens !
I very hope there will be soon a working solution.

could you help check with the UVCView and paste the information? not sure what product you are using, maybe the product manufacture heavily customized the driver.

My product i will use is a Naze32. For configuring this quadrocopter controller it has to be connected to the "Baseflight" GUI on my Windows-10 PC.
Perhaps i have a misunderstanding: is it necessary to connect this flightcontroller via USB before installing the CP210x driver ???
Without attached NAZE32-flightcontroller, the installation fails: no port description "Silicon Labs CP210x USB to UART Bridge (COM<>)" can be found on UVCView screen.
Into the "DPINST-file" I foud this text below. -> Interesting may be the text "Driver will be installed when plugged in." in the third from last column.

->> Next step: I will wait till the NAZE32 will be delivered to me an then i will attach it to the PC and try the driverinstallation again - maybe it works. Or do you have another idea, a hint or can you agree with me ?
Kind regards and thanks for support:
Peter from Switzerland.

Read the Knowledge Base article carefully, try get the vid/pid of this product with UVCView and confirm it was supported by the Silabs original driver or not. I strongly suggest you contact the quadrocopter manufacture to get the driver if the CP2102 device is hevily customized.

I've been trying to install the CP210x drivers on my Windows 10 (64-Bit) machines but on both of them I'm experiencing the same symptoms w/o any success;
- Using CP210xVCPInstaller_x64.exe and the installation completes successfully to install the version 6.7 which I downloaded from http://www.silabs.com/products/development-tools/s
- After the installation I can see the driver name in 'Programs and Features' in Control Panel but I notice that silabser.sys is not copied over to windows\system32\drivers. However, WdfCoInstaller01011.dll exists under windows\system32 from another driver installation and it is not touched during this installation.
- I checked the setupapi.dev.log file (attached) and it shows success without any errors but I see no trace of the DLL registrations in the log file.
- When I plug my physical device (Adafruit Feather Huzzah) which requires this driver, I don't see a new COM port created in device manager since the driver is actually not installed even though the installer says it is finished successfully.
I'd appreciate if anyone has any advise as to how to resolve or troubleshoot this problem.

Since this is a 3rd party end product that use CP210x, not sure if the product manufacture customized the driver and procut. Could you have a look on below KB and give us the VID/PID of this product?

Thanks for the reply. I figured out what the problem was;
- First off, the problem has nothing to do with Feather Huzzah board being a 3-rd party product. I'm just trying to install the CP210x drivers which is provided by Silicon Labs.
- Actually there was no problem with the driver installation when it said it finished successfully. I was expecting to see the silabeser.sys to appear in windows\system32\drivers folder as soon as I completed the driver installation. However, silabser.sys is copied to this folder only during the first time a device with CP2104 chip is plugged in to a USB port and the virtual COM port is created in Device Manager.
- My problem, apparently, was that I was using a very short MicroUSB cable that only had the power wires but not the data wires. I was under the impression that all MicroUSB cables had all the power and data lines by default/standards. But I was mistaken. I spent 2 days trying to figure out what the problem was with the board or the CP210x drivers. As soon as switched to a normal MicroUSB cable that I used for my phone sync everything worked fine. Virtual COM port appeared in Device Manager and the silabser.sys showed up in windows\system32\driver folder.
- Apparently Windows stores these files in a driver repository folder during the initial installation and only copies them over to system32\drivers folder when a device that needs these drivers for the first time when it is plugged in to a USB port.
Hope this helps to anyone having similar symptoms in the future.

I have been tasked with creating a Win10 VCP Driver using AN220 to add our customized VID/PID.
Creating the drivers, Version: 18.104.22.168, and running tests with Win10 32bit and Win7 32bit I am finding that our application is causing windows to BSOD. The 64 bit equivalent OSes are running fine. The BSOD occurs during memory read/write functions if that helps any.
Trying to figure the cause of the error I reinstalled an older customized driver version, specifically 22.214.171.124. With this driver our application is able to run and perform the read/write functions without any errors.
That is why I am here now. The only difference in both scenarios are the CP210xVCP drivers.
Any open or known reasons why 126.96.36.199 x86 drivers are causing Windows 32bit to crash?

I am trying to load the driver so I can use my Yaesu FTDX-3000 and have CAT control of the radio.
The driver would not even load to my machine. I am using a HP 64 bit laptop only about a year old. Was using Windows 8.1 and upped it to Windows 10.
I get a dialog box error msg when running the install wizard:
"The device driver installation wizard was unable to find any drivers designed for your machine".
Sure would like to get started using the digital modes on the radio!

Since this is a product from 3rd party that only a CP210x was used, I suggest you take a look below KB to check if customer customized the CP210x and the driver provided by silabs not work for this product.

I was trying to download the direct driver Windows 7/8/8.1/10 (v6.7.4)
but the link for it showed below seems not the right link.
Could anyone fix this? Thanks.

I don't think we have a special version v6.7.2 for ARM core.
Not sure if the WinCE version is ok for you?
04-17-2017 03:29 AM
@delu Thanks for the reply.
I believe v6.7.2 have arm support. Got this information from link http://www.silabs.com/documents/public/release-not
04-17-2017 03:48 AM
I think it was version 6.7.4 rather than 6.7.2.
The release note was for 6.7.4.
