Describe the bug
Web USB sample (./samples/subsys/usb/webusb/) fails TD 9.21: LPM L1 Suspend Resume Test

To Reproduce
Build and flash ./samples/subsys/usb/webusb/ and perform USB3CV tests on the device.

Expected behavior
The test should have passed.

Logs and console output
aaa

Environment (please complete the following information):

  • OS: Tests are run under Windows OS as they are developed for it.
  • Toolchain zzephyr-sdk v0.11.3
  • 72d5dee

Impact
The impact is very low as I don't think there are many customers willing to use WebUSB.
The sample deserve to be rewritten. Firsts insights: the BOS descriptor lacks in some parts
described in USB Link Power Management ECN - a part of USB 2.0 spec.

WebUSB sample does not provide relevant descriptor. I've added implementation and the test is passing. Will post asap.
