Part Number: AM5728

Tool/software: Linux

Connect dlp4500 module with am5728 evm board, write test function directly to verify that dlp4500 module can be recognized, fail to call hid_open (0x04510x6401, null) or hid_enumerate (0x04551, 0x6401). Is there no dlp driver code on the am5728 evm board? Where can I find the driver code for dlp4500, thank you!

    Hi,

    hiddev vs hidraw is not TI platform related, it is just a generic Linux question, so the question is not supported on this forum. However, I guess the kernel you used on AM5728 doesn't have usb hidraw driver enabled which causes the issue. Please check if CONFIG_HIDRAW is set or not in your kernel on AM5728. If not, you can enable it and rebuild the kernel.
