This is an extension of my earlier question. There I thought tlp was the culprit and stopped the service and it worked. But when I try to run my laptop on battery, again USB devices are not working. Work for few seconds and then stops.

lsusb shows my devices and dmesg

In tlp-stat

Bus 001 Device 002 ID 413c:250e control = on, autosuspend_delay_ms = -1000 -- Dell Computer Corp. Dell Laser Mouse MS3220 (usbhid)

I had tried installing linux-hwe-22.04, stopping tlp , configuring tlp as mentioned here.

I am really frustrated with Ubuntu 22.04.

    When you're on battery, your laptop supplies less power to its USB ports. What other devices are you powering via USB? Try: Purchase a "Powered USB Hub" locally or from Amazon or ... I realize that plugging the USB Hub into the wall anchors the laptop. Check your Manufacturer's documentation. Explore your BIOS. Is there a POWER section, and can you configure USB Power? YMMV. – waltinator Aug 03 '23 at 17:57

    It looks to me that the mouse is underpowered, and repeatedly coming to life, telling the hardware "I'm a mouse", then dying. – waltinator Aug 03 '23 at 18:00
  • @waltinator I had tried finding any such config in BIOS, but couldnt find. My laptop model is hp probook 455 g6 with AMD Ryzen 7 PRO 2700U w. This issue was not there with Ubuntu 20.04. I upgraded from it to 22.04 – Sachith Muhandiram Aug 04 '23 at 02:20

After long debugging days, I found the solution. It also related to tlp.

In /etc/tlp.conf file.

 Runtime Power Management for PCI(e) bus devices: on=disable, auto=enable.
# Default: on (AC), auto (BAT)

RUNTIME_PM_ON_AC=on
RUNTIME_PM_ON_BAT=on

I had to set RUNTIME_PM_ON_BAT=on, it was originally set auto.
Now external usb keyboard and mouse are working without an issue on battery.
