J721EXSOMXEVM: Unrecognized after connecting to USB device

Hi team,

To avoid ambiguity, I would like to add the problem description.

The system on the TDA4 board cannot recognize the USB device connected to the TDA4 board.

Looking forward to your reply.

Regards,

Vivian

Hi Vivian,

Please elaborate on which USB device you are connecting and also which exact port?

Hi Keerthy，

Thanks for your quick reply.

I had tried 3 usb devices.
1. A portable flash disk, whose id is "DiskSanDisk_Ultra_USB_3.0___1.00"
2. A logitech camera with id "VID_046D & PID_08AF"
3. Another camera with id "VID_0C45&PID_6366"

They all can't be detected by the tda4 linux system, but function well on my PC.

Regards,

Vivian

Hi Keerthy，

In additon, the USB2.0 Type-A stacked Ports and USB3.1 Type-C port on the board are tried.

I connected a USB mouse & got the above detection logs.

Now lsusb reports as below on j721e-EVM with default 8.2 Linux SDK:

Hi  Keerthy,

Thanks for your quick reply.

I will forward your answer to the customer.

Thanks & Regards,

Vivian

Hi Keerthy,

Customer reply

"Under normal working conditions, the log connected to the USB device should be like this, but we regret that we can't recognize it and don't feed back the above information.

Can you give us some troubleshooting suggestions based on your professional experience. For example, does it need to be configured before connecting USB devices, or how to troubleshoot hardware failures?"

Thanks & Regards,

Vivian

Hi Vivian,

Could you please try with a different pen drives? Or a different USB device like a Mouse?
Can they move to the latest SDK: https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-J721E/08.02.00.03
