With new version of macOS released which is macOS Big Sur 11.0.x, the latest version of our VCP driver for Macintosh OSX (v5.3.5) now becomes incompatible. The reason for this is because of new driver model change on macOS which you can find more information from links below:
We currently are working to update our driver to fix this issue, although due to testing requirements, we do not expect the new version of driver to be available on our website for now. So please be up to date on our page for VCP drivers below for latest information regarding to the release of the updated VCP driver for macOS Big Sur 11.0.x:
We've recently become aware of an issue with a new update to Windows 10 and our CP210x VCP "Universal" Driver for Windows 10, driver version v10.1.1. When attempting to install the driver, an error is given by Windows that states "A service installation section in this INF is invalid." This occurs because Windows has changed drive INF requirements slightly, and our current driver's INF file does not meet these requirements.
We currently are working to fix this issue, although due to testing and recertification requirements, we do not expect the fixed driver to be available until mid-June.
A work-around exists currently, but it involves manually editing the .INF file for the driver. This causes another issue - the driver is no longer signed in this case, so the driver must be forced to install, and Windows will show a warning that the driver is unsigned.
Firstly, the work-around is as follows:
Download the Windows 10 Universal driver from here: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
Edit the .inf file with this driver, performing the following modifications:
On or around line 118, change/edit
ServiceBinary = %13%\silabser.sys
ServiceBinary = %12%\silabser.sys
And on or around line 160, change/edit
Silabser_CopyFiles_FileListSection = 13 ; Driver package's Driver Store directory (%WINDIR%\System32\DriverStore\FileRepository ) (was 12 Drivers directory (%SystemRoot%\system32\drivers))
Silabser_CopyFiles_FileListSection = 12 ; Driver package's Driver Store directory (%WINDIR%\System32\DriverStore\FileRepository ) (was 12 Drivers directory (%SystemRoot%\system32\drivers))
I.e. replace every 13 in the file with 12.
Once these changes are made, attempt to re-install the driver. A warning will be shown that the driver is unsigned, but you can ignore this for now. If you do not receive a warning issue, or if Windows refuses to install the unsigned driver (you may get an error about the hash being invalid), you can disable driver signing enforcement by following these instructions: https://www.maketecheasier.com/install-unsigned-drivers-windows10/
Alternatively, rolling back to a previous build of Windows also resolves the issue.

I have 2 questions:
1. I am using CP2102NA02QFN20 on customer board. The VCP driver from SiLabs site is installed, COM port works just fine.
But, when I try to operate GPIO - nothing works.
2. I configured CP2102N to PID 0EA61 - but can not return it to 0EA60. How can I do it?
when I updated my WIN10 to 2004 version,
::ReadFile from serial will be very slow, 30ms+ to get result from API.
this issue happened on 20+ PC that upgraded 2004.
I am very sure it's a driver issue, problem solved after I replace CP2102N to another chip.
PLEASE, It's a big problem.
Dear Silicon lab Team,
Thank you for your support.
This is Takashi.
Can you let me know Junction Temperature for CP2103GM ?
I couldn't find it from Datasheet, though.
I'm using an Esp32 Wroom Devkit with a cp2102 onboard. The current draw with my application running is about 20 ma. If I disconnect the usb connector, the current drops to about 10ma. If I reconnect the usb connector, the current returns to 20ma. If i leave the usb disconnected, and repower(not reset) the board, current goes to 20ma. Why isn't it 10? Does this have something to do with usb powered vs self powered mode of the cp2102? It appears the cp2102 is configured in self powered mode in that REGIN is wired to Vdd.
Hi I have a USB RFID Reader/Writer with name "Silicon labs CP210x", I develop a windows app with C# in Visual studio 2015 that could Read/Write on RFID Card, its worked fine...
I change my Windows on my notebook (prev Windows and new Windows are Windows 10) and install Visual Studio 2017...Now when I open solution and run application see this error:
Message=The maximum baud rate for the device is 8190.
While googling in this error, I see some guys say that the error related to baudrate of reader But the reader and MySainsburys my application work fine until I change Windows and it should not related to baudrate ...ِI think its dont related to driver because the driver work on prev windows fine...Does anyone have any experience in this error?
We have developed 100 devices in which we are using cpt112s for touch input.
We are using an overlay as a glass of 4.5 mm however the touch is not working.
Could you please suggest if whats the limitation of overlay material used for touch input?
We are integrating "MSP432P401R" with "VP3300 IDTech NFC Reader" VP3300 NFC reader has USB HID.
We are sending data commands from MSP432 UART to CP2102 and this is connected with VP3300 USB Micro port.
So, we are not getting any response from VP3300. So my question is if we want to use CP2102 as inter mediator, is there any driver need to install in microcontroller or VP3300 device. IDTech dont have any driver for this.
If I want to communicate between this what should I do?. How to Convert VP3300 USB signals to UART signals? Please help me to resolve this issue.
If you need any information, let me know.
If CP2102 is not applicable, then can I use CP2104 / CP2110 directly.
I see in the release notes from September 2020 that the CP2110 is not listed as supported by the latest Universal Windows Driver. See https://www.silabs.com/documents/public/release-notes/CP210x_Universal_Windows_Driver_ReleaseNotes.txt.
Additionally, I have heard that the CP2110 product ID is not included in the driver source code, but I have not verified this myself.
Is this accurate? If so, when can we expect to see an updated driver?
We have a product that uses a CP210x for the USB-to-serial interface. We use the VCP drivers on Windows and macOS.
I would like to talk to the device over WebUSB - through a browser.
Is there any documentation to do this?
My questions below :
1. From Simiplicity Studio 4, there is an intel-formatted hex file associated with each project (e.g. cp2615_a01_gm.hex). This file was generated by the graphical tool after configuration. Is this an appropriate file that can be used by a universal EEPROM programmer to program CP2615?
2. The hex file has start address = 0xE000 and end address = 0xE3CF. However, when i use a universal programmer to read back the EEPROM content of CP2615, it always starts at 0x0000. Why there is an address offset of 0xE000 in the hex file ?
3. By inspecting the configuration content of CP2615, there is always a 0x00 at 0x3D0 followed by padding 0xFFx. The hex file generated by Simplicity Studio4 only specifies the content from 0x0000 to 0x03CF (ignoring the 0xE000 address offset). What is that extra 0x00 at 0x3D0 for?
4. Any document available to explain the structure of the configuration EEPROM inside CP2615?
I am trying to use the CP2102N-EB development board to communicate with an ARM microcontroller. This microcontroller's USB port is configured as CDC host.
I am writing the firmware for this microcontroller.
I thought the CP2102N's device class would be 0x02 (CDC Device). But I now know that it identifies as 0xFF (Vendor Specific)
Is there a way to configure the CP2102N to be able to communicate using standard CDC. Or do I have to write a specific driver for it?
Thanks in advance,
