Hi,
I'm currently running ubuntu 18.04 with a 4.15 kernel and i can observe very
high cpu usage to the systemd-udevd deamon.
removing the rule :
ATTR{bInterfaceClass}=="03", ATTR{bInterfaceSubClass}=="01",
ATTR{bInterfaceProtocol}=="02", \
ATTRS{bDeviceClass}=="00", ATTRS{idVendor}=="413c",
ATTRS{bmAttributes}=="e0", \
RUN+="hid2hci --method=dell --devpath=%p", ENV{HID2HCI_SWITCH}="1"
Solved the high CPU usage eventhough my bluetooth card is not available
anymore (as not in hci mode)
It seems that the command hid2hci creates a bind/unbind loop in udev
that is looping trying to set the device in hci mode. (that what udevadm
monitor seems to show, looping from bind to unbind for the device)
I suspect a0085f2510e8976614ad8f766b209448b385492f introduced a
regression (i have not tried to revert it yet).
Please not that there also seem to be a bug in hid2hci.c from bluez l148 :
if (err == 0) {
err = -1;
errno = EALREADY;
}
Correcting this and recompile bluez desn't solve the issue as cpu usage remains
very high.
Using a 4.13 kernel result in a normal CPU usage, this seems a
regression in 4.14.
Other people seems to have the same issue, here is a bug report related to this
:

Thanks a lot for your support,
Mathieu Tournier

removing the aforementioned rule solves the problem but leaves BT

I am also affected for device 413c:8156 (Dell Wireless 370 Bluetooth
Mini card) on Latitude E6400
For those looking for a quick fix: identify your bluetooth device ID
with "lsusb |grep luetooth" (e.g. 413c:8156 and 0a5c:4500 for me) and
then disable all matching entries in a line within this new file
/etc/udev/rules.d/81-bluetooth-hci.rules:
SUBSYSTEM=="usb", ATTRS{idVendor}=="413c", ATTRS{idProduct}=="8156",
ATTR{authorized}="0"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0a5c", ATTRS{idProduct}=="4500",

I have the exact same problem, also a Dell computer (Inspiron something). CPU load is almost always at 100% and temperature sensors measure over 100C! My computer has become unusable.
