Hi Expert,

I used VisionSDK_V2.9 to get the USB device on TDA2Ex but it failed, System response "unable to initialize libusb: -99".

The message is as below,

Hi,

No usb device found on the custom.
Add the following comparison table:

Use the same SD card,

But can not be found 488x0000.usb in /sys/kernel/debug.

Could you please give some suggestion here?

Whether the issue observed on TI-EVM or custom ?

Make sure all USB modules are installed/copied to filesytem.

Hi,

The issue occur on custom.

I use the same one SD card.
But there are different results.

TI-EVM

custom

I also confirm the usb_id status by modifying the driver.
drivers/extcon/extcon-usb-gpio.c

The "lsusb" is user space application, some problem, while intiializing libusb library or missing.

Looks like problem with your file system used. Can you try the filesystem of PSDKLA release/TI-EVM.

Hi,
But I use the same one SD card in VisionSDK_V2.9.
To test EVM and custom, run 'lsusb' only EVM is successful.

Looks some DT related issue. The phy driver probe is not successful or some dependency is not met.

Whether this issue is reproducible in TI-EVM or custom board ?

Hi,

This issue in custom board.

If 'usb1_id' do not through 'pcf8575',
Whether to modify GPIO driver? (drivers / extcon / extcon-usb-gpio.c)

J6 usb power if provided, not through the Power Management IC,
Is there any need to modify driver of Power Management IC(palmas)?

The USB-ID is not an issue here. The extcon frame work used to switch usb role between host and device mode without USB-ID.

From logs, seems like this issue related to another thread

Hi,

'DPLL locking failed for 4a008180' issue only occur on J6 ECO EVM.

Custom board don't have Power Management IC, will it be affected?
