Comment 3 for bug 1839693

 Hi there, sure I’m happy to try it. But I am a bit of a newbie, so I need exact steps on how to install this kernel and even better perhaps a screen share or some other way to communicate with someone while I am doing it. Thank you.

Title:
  p54usb module in linux-modules-extra-5.0.0-23-generic does not work

Status in linux-hwe package in Ubuntu:
  Incomplete

Bug description:
  I am using the Product: Dell Wireless 1450 Dual-band (802.11a/b/g) USB
  2.0 Adapter

  This relies on the p54usb driver. It works great on kernel 4.18. I
  upgraded to 5.0.0-3 and the device fails to start.

  On the older kernel, things seem good:
