I haven't provided all the information. Sorry. USB device not recognized on computer power-on(dmesg log is exactaly the same if the device is not connected. No recognition in any way). USB device RECOGNIZED on computer restart. USB device RECOGNIZED on insert after computer is booted. I include below the dmesg part that changes from a computer power-on to a computer restart. (this is for the "successful" boot). Going to test now to unload and load the driver.
