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.

This may be a very simple question but I realy do not know the answer :)
I have bought a ttl termal printer to use with PIC MCU. And I want to be familiar with printer command set.
I could not succeed to find original user manual for apropriate command set but in the attachment there is a manual of similar pirnter device.
Printer has GND RX TX DTR VH pins.
I have connect pints to CP 2102 in orde below
Printer GND -->GND CP2102
Printer RX-->TX CP2102
Printer TX-->RX CP2102
Printer DTR --->
Printer VH -->VCC CP2102
I use tera term to communicate with CP2102. In the attachment you can see settings of Tera Term.
My question is what should be appropriate settings of Tera Term ?
Is my connection right ?
What should be a simple command to print simple characters ?
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.
I'm having trouble installing the drivers into my Late 2011 MBP OSx High Sierra 10.13.6
I've found several posts in this forum, but none of them seem to have my same problem, mine is just that the installtion program will stop in the middle of installation, and will stay there forever, not finishing the installation. Does anybody else had this problem and knows how to fix it?
thanks in advance.
We have a customer computer where the driver has installed successfully, but our device is not being assigned a Port number. I've never seen this before. It simply lists under ports as 'CP210x USB to UART Bridge' with nothing after it.
Any help to identify and resolve this issue would be greatly appreciated. The computer appears to be a Windows 10 computer.
If I attempted to change the COM Port, it would cause the snap-in Console to crash.
I'd like to run the CP2105 bus powered and have the VIO set to the board 1.8V for the tx/rx voltage connected to an FPGA. If the CP2105 is powered from a host computer but the board is off (no 1.8V VIO) will the bus voltage try to backpower the FPGA I/O?
Thanks for the help,
I ordered a CP2102 USB-to-serial module from Ebay, but I found that the output labeled "3.3V" on the silkscreen actually measures at 4.25V. I thought it was just a bad part, but I found the same module on sale at Banggood, and the same problem is mentioned in reviews posted by three buyers. One of them had ordered three modules, and all of them were 4.25V. So it appears all of these modules output 4.25V instead of 3.3V. I can't use 4.25V because the microprocessor it will connect to has a maximum voltage of 3.6V.
This is the module I bought:
On the back side it says "CJMCU" and "BQ09615H2 2025a"
The chip is labeled:
I don't see anything in the datasheet that indicates the output of the regulator is adjustable. Can anyone offer an explanation for the 4.25V output? Could all the chips, or a large number of them, be faulty? That seems unlikely. It seems much more likely that this was done deliberately.
I also ordered another CP2102 module of a different design, and its 3.3V output is correct:
But it is bigger than the first module, and less suitable for my project. So I would like to find a source for the first module with an on-spec 3.3V output, if that exists.
Any help or explanation would be appeciated.
Situation: I have a Davis VP2 weather station connected to my Imac via USB connection. Every 2.5 seconds it sends a small packet of data to my Mac which is running weatherdisplay (WD) software.
M y Imac was running High Sierra and using version 5.0.2 of your CP210 Uart driver.
Historically it has worked fairly well. I have been plagued by very random situations where the records were not being sent to my mac and WD. The developer was at a loss. He put in some logic so that if no records were sent in xx time it would restart the program This has been a great work around.
However, this weekend I bought a new Imac which came with Mojave. I grabbed the latest Silabs CP210 driver (5.2.2). The number of times where no data has been sent to the mac has gone up incredibly. Now it is at the point where it’s not getting any data.
I was at my mac when it happened and captured some logs from WD. I noticed these errors (I have screen shots of these if you need them):
ERROR: Bad file descriptor at time/date xx
ERROR: Inappropriate ioctl for device at time/date xx
Comport error 9: bad file descriptor
I shared these with the developer. He believes this is with the driver.
Is there any way I could get some help please? If you need anything from me let me know.
What I’m going to try (when I get home today) is to uninstall and apply the 5.0.2 version of the driver.
Btw your steps say to run the uninstaller. However, where is the uninstaller script located?
Thank you !!!
I'm not a programmer, so my questions may not make much sense. But I hope someone can help.
I'm running Windows 7/64 with the VCP driver installed (v220.127.116.111). I want to manipulate the state of two GPIO ports on the CP2102N to generate the BSL invocation sequence required for TI MSP430 MCUs. The pins would be the TXT(.0) and RXT (.1) pins numally used for LEDs. I don't need to read the pins, just open the port, bring them high and low in a particular pattern, then close the port. I've used AN197 to develop a program in C that does ordinary communications involving the CP2102, and it works fine. I've also read through AN223 and AN223SW, but don't understand them.
If I write a program to deal with these GPIO pins, is it sufficient to place that program and the runtime DLL in a folder and run my program from there? If not, what other files need to be there?
Can my program be written in C, or does it have to be C++? I've been using the LCC-Win32 compiler.
Where can I find the latest version of the runtime DLL that works with the CP2102N?
Since it's the TXT and RXT pins, are there VCP driver commands already implemented to control those pins?
Thanks for any help.
Today I installed the Catalina beta (macOS 10.15), and it told me that an extension for the CP2102 was not going to work because it’s still 32-bit only.
Since Apple warned us a few years ago that 32-bit code was deprecated, and told us a year ago that this year‘s macOS would not be supporting 32-bit code any more, how come there is still no 64-bit driver for this commonly-used component? (I think it’s the VCP driver?)
I hope that the driver is being updated to 64-bit and it’s just taking a long time because it wasn’t a high priority. Except that now there are 3-4 months before we will need it, and it should be a high priority.
For now, I need to run two operating systems on my Mac. After Catalina is released, I am hoping that number goes down to 1.
I know, that it can be not correct forum, but i do not know where i can ask for my question.
Could someone explain how should look setup to measuring return loss on fxs port (using wandel & goltermann pcm-4) with 2 wire?
What port on pcm-4 should be used (some photo or draw), how to connect test equipment and pcm-4?
Manual for pcm-4 do not explain test setup.
i found only this:
I have problem with usb device. Inside of this device use CP2102 chip to convert serial to USB.
But when I use my mcu to access this device. I need the usb to serial (host USB) to control it.
How to make this Host Communication? What kind of chip USB to make USB Host? Or Have some breakout?
