Same bug affects me on dell Latitude E7450 on freshly installed Bionic 18.04.1. Kernel 4.15.0-29-generic.
- After suspend/resume newly inserted USB devices are not detected and not listed by lsusb.
- Repeating suspend/resume with the device still inserted in the port solves the problem. At this point devices can be remove and inserted again and everything works as supposed.

I attached a dmesg output.
