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.
We are using a CP2615 bridge to acquire audio signal on Windowds and Android systems. We would like to extend or to develop a new product for IOS.
But I read that CP2614 is not recommended for new developments .... Have you a solution for an USB audio bridge working on IOS ?
I designed a USB to RS485 converter on CP2102N, but it work only at 2400 baudrate.
I work on OS W7/W10 with latest drivers for 2102N.
Tried different settings BR in the Xpress Conf, but nothing helps...
I connect my custom board with CPT112S to Simplicity Studio through the USB Debug Adapter
.(The configuration in Xpress Configurator working good (read and write to CPT112S
(When I'm going to the Capacitive Sense Profiler and try to connect my device (to see Raw Data
the Simplicity Studio send message "device in sleep mode. touch sensor..." and the red LED lighting on the USB Debug Adapter
?What the problem
I have a CP2615 installed on a custom PCB and I am having trouble verifying the part.
My current setup is:
0. VDD and REGIN initializes to 3.3V, VBUS to around 3.1V
1. pull RST low
2. approx 1 sec delay
3. pull CFGMODE high
4. approx 1 sec delay
5. pull RST high
Then I measure I2S SCK and I2S LRCK, which flatlines at 0V. I assume I should see clock signals.
What am I doing wrong here?
When selling a product using the CP2102N, is it mandatory to request a PID from SiLabs or to have a full unique VID/PID, or is it also possible to keep the default VID/PID?
If keeping the default VID/PID is allowed, can the product string and/or serial string be changed?
I am having a strange problem using the CP210x USB to UART Bridge Driver.
1) Windows 10, build 1803
2) CP210x Driver version: 22.214.171.1241 (Driver Date: 2016-09-19)
3) STM32F407 MCU => PC (Serial Communication)
4) Data receiving program: Python 2.7, pyserial 3.4
5) Serial communication
Data 8 bit
1 stop bit
no flow control.
In Windows 10, connect to USB and receive data using Python. (pyserial)
At first, reception is good.
After 1 minute from receiving, the data is broken as follows.
(use pyserial in python to print as it is received)
The MCU is transferring the data correctly (already check the transmit cycle, waveform with an oscilloscope)
When PC receiving data.. but it seems that the data buffer is not being filled properly for some reason.
My efforts to resolve
Changes for VCP Driver
MCUSW-134 | Fixed an issue with handling of IOCTL_SERIAL_SET_WAIT_MASK,
| IOCTL_SERIAL_WAIT_ON_MASK, with the SERIAL_EV_RXCHAR event
| and data arriving from the device into the driver. Previously,
| an indication of arriving data was made before making the data
| available, causing, in some conditions, subsequent requests
| for data after notification
| any data.
After read driver release note, i install newest windows 10 universal driver (v.10.1.3.2130)
i confirmed that the data was received normally after updating to the windows 10 universal driver. (received data is not broken!!!)
So it was fixed after the update.
By the way....
My questions and problems
The CP210x version of my other computer is v126.96.36.1990.
It's the same windows 10 build 1803, but it works fine without errors. (I did not install anything else on Windows 10)
v188.8.131.520 The date of this driver is 2016-03-28.
It does not come out well in Google search.
Why does this difference occur? What is the factors that will cause this problem?
I think it's a driver problem, but I want to know the cause.
Thank you in advance.
I was able to write the configuration to the chip CP2615 but once rebooted in normal mode, it isn't detected by PC USB.
So question is what I am doing wrong.
1. I configure chip in Simplicity Studio
2. I choose "cp2615_a01_gm.hex" file, grab the data segments out and flash them via I2C (Raspbery PI script)...
3. The programming is started by first line and goes to CP2615 starting from MSB address=0x00 and LSB address=0x00. For verification I read the config from the chip, and I get exactly the same bytes which I wrote:

Except the tool reads some more bytes at the end of the dump with "4e 44"... with ff, but that I guess is not a problem.
but otherwise the hex dump is completely the same as in square box exported from Simplicity Studio...
The chip is self powered with USB data lines connected to PIN 4 (+) and 5 (-) and USB GND and shield grounded to to the chip ground.
The strange thing in hex file format (which is Intel Hex file format) I see that all addresses starts with Exxx, why is this so? Also according the datasheet, the "The configuration block consists of 2048 bytes of non-volatile flash memory mapped to address range 0x0000-0x07FF". Thus Exxx will not even fit...
Please help, how can I get chip running?
I've downloaded the current version on a couple of laptops.
The error on both in Device Manager is "This device cannot start. (Code 10). The specified request is not a valid operation for the target device."
I downloaded a CP210xPortReadWriteExample V3.1a. When I try to Write Latch or Read Latch, it appears Error. How can I use it? Am I download a wrong version? The UART communication is successful. The P/N is CP2102N-A01-GQFN28R.
If I attach a CP2102N-MINIEK to a Windows-10 machine (Silabs driver ver 10.1.3.2130) running Putty, and configure flow control to either XON/XOFF or RTS/CTS then no data is send out on TXD from CP2102N. The only way to make communication work is to configure flow control to None.
Has anyone managed to make the CP2102N-MINIEK work with flow Control enabled?
I've connected CTS to GND to make sure that the CP2102N could send data but it still doesn't work. Any suggestion to make RTS/CTS hardware flow control to work?
What is terminals plating, materials and thickness of each layer of plating
