A newly inserted USB device is
sometimes not recognized without re-plugging USB-OTG adapter.
When unplugging a USB stick from the USB-OTG adapter and inserting a new one, the new USB stick is not detected.
When unplugging the USB-OTG adapter from the laptop and inserting it again, the new USB stick is recognized.
Is this normal? Has someone else had this experience? Has anyone had a similar experience? And how to detect the new device without physically unplugging the USB-OTG adapter?
For clarity:
Code:
USB flash drive
| USB-A - plugging in new device = new device not detected.
| | USB-OTG - re-plugging = new device detected.

dmesg:
Code:

No new dmesg appear when plugging the new device.
How come a USB device is sometimes not recognized without re-plugging the USB-OTG adapter?
