false alarm raised by usb3/storage-server xhci_hcd detection

It seems the fix has been merged. See the commit 182f27d6eb131a49df247c1b9d79288622f41f9f of plainbox-provider-checkbox project.

Next step:
I will try to run the same usb3 job with checkbox codebase from checkbox dev PPA.

I did not resolve this issue with the latest checkbox stack.

what does usb-devices say about the device? It should confirm the driver in use.

For example:
T: Bus=01 Lev=01 Prnt=01 Port=06 Cnt=06 Dev#= 19 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

I: If#=0x1 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=usbhid

It says my keyboard is using usbhid driver.

I wonder if this is an ARM thing... run this just now on my intel desktop and it does work fine (as it does on any other intel machine).

I would call this a legitimate issue with that SoC at the moment...

By the way, from checkbox we could see the usb devices and their block numbers, SanDisk usb sticks as sda and sdc, by running:

$ sudo checkbox-cli run -t file --transport-where /tmp/submition-device.tar.xz -f com.canonical.plainbox::tar com.canonical.certification::device

When running the script on Mt. Jade, the enumerator of `enumerator = GUdev.Enumerator(client=udev_client)` does not return any device with driver name "xhci-hcd" but "xhci_hcd". (watch out the dash vs. under score)

Thus, this issue may be specific to the Mt. Jade platform and some other platforms. It does not impacts the platforms with "xhci-hcd".

Next step:
I will create a merge proposal and perform some regression test for the "new" parser.
