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.

Currently, we are working on our custom android board. we used the Snapdragon 210 Processor.
we build Google android 8.1 for this processor.
we require 4 serial ports for our application. also, we required a VCP driver that can integrate with the android source code.
Please suggest to us IC for our application.
I am developing interface with CPT112M and host controller.
Working of system is like, Host controller will remain in sleep mode and it get wake-up after detecting proximity event so that it will turn Keyboard back-light. When key is detected it will read and process. After some time host controller and touch controller will go in to sleep mode (or low power mode).
Presently I have observed that CPT112 is giving interrupt only after touch detection and not after proximity detection.But when I connect board with Simplicity Studio and check for proximity and touch status in "Capacitive Sense Profiler" it shows proximity status ON when I take finger close to sensor. Is it giving any interrupt or any other mechanism available to detect proximity event.
Kindly guide me to resolve proximity event detection issue.
Thanks & Regards,
I have CP210x USB to UART Bridges installed on a Win10 computer. One is assigned COM3, the other one COM8. After a reboot the com ports are swapped and the connected devices no longer work.
Is there any way to fix the com port assignment?
I found several articles on this topic, also on the forum. They have dead links or do not apply to WIN 10.
As the title states, can I leave SUSPEND, SUSPENDb, WAKEUP and GPIO0-GPIO3 float if unused?
Also, same with RTS and CTS, can those float too?
I've attached the schematics of my circuit if you wanna have a look and see if it seems reasonable.
Hi i bought chip CP2102 from China, after assembly. device shown as Verifone to Modem.
and i try to use tool (CP21x Set IDs) but it shown Custom Data Locked.
so how to reset it to original firmware ?
I am completely new to PCB design and figured I would give it a shot. I want to create one PCB that essentially contains two Arduinos in one package. The obvious way to do this is by simply duplicating the Arduino PCB side-by-side, which would contain two CP2102s and two USB ports. However, I would like to use a single USB port that could then be used to program both Arduinos separately (as in, separate sketches for each). If I read correctly, the CP2105 would be able to handle this, as I could connect both Arduinos to this one chip, then run the output of that chip to the single USB port. Is this correct? Also, if it is, which interface will be listed as the first com port (example: COM3 in Windows), the "Enhanced" UART interface, or the "Standard" one? Then the other would be the next listed com port (example: COM4 in Windows)?
Thank you very much for your time!
I have been asking for over a year for a fix to the current CP210X OS X drivers which will allow sane naming of multiple device names. The seemingly random assignment of a number to the end of the SLAB_USBtoUART device name is causing havoc every time I restart my Mac with two CP210X devices attached.
Other drivers for other devices append something unique to the device, like a serial number, to the device name so that it is not only unique but associated with the same physical component no matter what. Will you folks please look at doing this soon with the CP210X driver?
I bought the CP2102 for having a com port on my computer. I want to use the RTS 'signal' to switch on and off my transceiver (also called PTT switch). Many HAM-software use the RTS signal to switch. But... When i use HAM communication software it switch my transceiver to tx when it had to be rx and to rx when it had to be tx. In the mean time i have learned that RTS (and DTR) on startup are active high. I am not a programmer. How can i fix this easely so that RTS is active low on startup?
I am using CP2112-EK to connect a I2C Slave, which is +5V power supplied.
The IC CP2112 of the EK is burnt/damaged, after I removed the J7 jumper. But there are two 10k ohms resistors pulled up to +5V at slave side.
Can SDA/SCL port of CP2112 stand +5V? Can the CP2112 and Slave connect like one in attached picture? What's the root cause of the EK burnt?
Dear Support team,
We are working on a product where we have been using the CP2102N-GQFN24 and connected the board to USB power of Lenovo T480 and T490 as well as the Dell Inspiron
When we connect the device and power it ON the CP2102 goes bust either immediately or after running for 10 minutes of so. We blew up as many as 10 CP2102s already and are wondering what might be the causes of the CP2102 going bust.
Can you suggest what might be the challenge?
We are currently using the CP2102N in our solution but we need to now support USB3.0. Is there a pin replacement of the CP2102N with a chipset that can support USB3.0?
We have a desktop software application that includes the VCP driver for CP2104.
We need: Silicon Labs VCP Driver.pkg (Notarized & Stapled) so that we can include the driver in our installers.
Also, we would like to have the command line options used to get this pkg file notarized.
I have installed the latest drivers from the web page https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
after the installation when I tried to connect to the serial device by selecting SLAB_USBtoUART at 9600 baud rate my program stops working and nothing works
I tried different programs CoolTerm, Arduino, ESplorer each and every program stops working after I try to connect to the device(NodeMCU - esp8266). Can anyone please tell me where I did wrong
Here is my system specification:
macOS Sierra v10.12.6
