How to re-identify devices connected to USB ports

Fri Mar 29, 2019 10:28 am

Let's say, some device(s) connected to USB. What command/sequence should be performed, to "detect" all these devices, currently connected?

So you want to shutdown the device and restart it? Or simply show what attached?

`lsub ` will list all attached devices.

This might help with resets

Yes and no. I want to try re-initializing attached devices without reboot. I have a problem which seems to be hard to solve, and try different approaches:

Looks like the device is NOT initialized during reboot itself, and I'm trying to make workaround to initialize it manually after the boot
