It seems there's a bug (or a feature) in kernel, which switches the devices in power save mode after suspend, without triggering UDEV events. Here's what tlp developer says: https://github.com/linrunner/TLP/issues/545 >Imho the kernel never issued udev new device events for existing devices after >resume. You may look into it yourself by enabling TLP's trace mode with >TLP_DEBUG="run udev usb". I use tlp software, with bluetooth module powersave blacklist configured and patch which is mentioned in the URL above applied (`set_usb_suspend 0 auto` in tlp resume handler) -- You may reply to this email to add a comment.
