Part Number: PROCESSOR-SDK-AM335X

Hi,

I met a USB driver problem on AM3358-EVM.

I would like to establish an USB connection between PC Windows 10 and AM3358-EVM(USB0, not host USB1).

But my PC can not identify this USB device and shows a question mark in my windows device manager.

Could you provide AM3358-EVM driver on windows 10 ?

Thanks a lot.

    Hi,

    Is your board running linux when it is connected to the Windows PC?

    What version of the Processor SDK release do you use?

    What USB gadget driver is loaded in your linux?

    Hi Bin,

    1. yes, am335x-evm base board is running linux when I connect it as device to PC.

    2. I use WRLinux BSP for TI AM335x version. (  github.com/.../wrlinux-x.git wrlinux-x )

    3. I don't really understand the question, do you mean the USB support feature in kernel menuconfig? Please see below picture.

    This forum only supports TI released Processor SDK.

    No, I didn't mean kernel config settings.

    USB device has many different classes, for example, USB hub, thumb drive, mouse/keyboard ...

    When you want a Linux platform to be a USB device, you have to load a Linux USB gadget driver on the board which provides the corresponding USB gadget class functions. If you don't load any USB gadget driver, the board won't talk to the USB host.
