We have a custom board carrier board where we directly connected the USB pins on the Intel 8265 module (for Bluetooth) to the USB2 pins on the Jetson Nano, without a USB hub.
Sometimes (not all the time), we will see that the Bluetooth is not enumerated over USB. We added some extra debugging in the xhci_hcd driver to understand the error when the device fails to enumerate.
The kernel log is attached.
Can you provide any insight?
