This problem can be seen on any machine actually. I was seeing it earlier. The key is to NOT run "lsusb". This kicks off a fresh scan of the USB bus and then it's seen.

So to reproduce:

1) Connect USB hub to usb port
2) Connect any device to it .. in this case try a USB stick .. though it's for any
* DO NOT RUN "lsusb"
3) Check dmesg and notice the device is not seen
4) Run "lsusb" and notice now your device is seen.

Appears a problem only with this kernel. As reported it works fine with 8.10. Will try and narrow down the change that may fix this issue.
