Hi @vkj,
- Do you observed the same behavious on Toradex Carrier board (also let me know which one you have) with the same setup.
Verdin iMX8MP ------>USB HUB------->USB-to-UART. - Did you make any device tree changes?
- A similar related post says that issue is no more observed after updating to BSP 7, can you test and confirm?
- If the issue is still observed after updating the BSP, could you share the schematic of USB section for better understanding? (share at support.in@toradex.com)
