USB2 and USB3 are mistakenly marked as unsupported as the USB controller enters the suspended state

[weizhenwu]

Bug Description

USB2 and USB3 are marked as unsupported mistakenly hence some of the USB jobs get skipped.
The resource job com.canonical.certification::usb relies on the command lsusb to determine if USB2/USB3 are supported

However, on Qualcomm's platform, the USB controller will auto-suspend when the cable/storage is removed.
This results in no output from the command lsusb, hence USB2/USB3 is marked as unsupported.

Expected result

There should be a reliable way to check if USB2 and USB3 are supported regardless of the USB controller status.

Environment

• OS: 22.04 Server
• Checkbox Version: snap
• DUT: 202403-33869

To Reproduce

Run USB resource job by
$ checkbox-carmel-classic.checkbox-cli run com.canonical.certification::usb

Compare the output in two different scenarios

• connecting a USB storage to the system
• removing the USB storage from the system
