Hi

I have made a board where i used CP2105 in order to pragram BCM20737s. Problem is that my board is not detected by my PC it gives the message "One of the USB device connected is not detected by the system due to malfunction. Connect device again or change the device". I have connected the device several time and i have install the CP210x driver but still it gives the same error. I wonder that may be i made a mistake on schematics. I have attached the schematic kindly look into this.

Hello ussid,

The schematic looks fine.  This is definitely a Silicon Labs issue.

Have you checked with them?

Our SDK provides the installation of the CP2105 drivers.

You may want to check with SiLabs support on this issue.

Thanks

JT

Hello Ussid,,

Did you download the drivers from the CP2105 Web Site?

Hello ussid,

Have you followed our WICED Sense Kit Schematic?

That should provide a working solution

Thanks

Have you searched the Silicon Labs web site for CP2105 32bit drivers?
