Is this really hub debounce timeout or usb_pgood_delay ?
Which devices are those, include that in the commit message.
Yes, timeout is related to USB connect/disconnect signal bounces not
about bus stability during init.
Issue was mainly observed with legacy flash drives. Maybe I will change
commit text from "Some USB devices need more time to be initialized..."
to "Some old USB flash drives need more time to be initialized during
connect or disconnect events ..."?
Note that I am not modifying the default Kconfig value in general;
change is only made for an SoCFPGA devkit we tested.
