lubuntu mtp probe is failing to find a usb device and install is effectively stalled

Asked by L. P. Luigi Espenlaub

Lubuntu Live Disk install [ISO]
lubuntu mtp probe is trying to find a mtp device on my HP110-220z on buss six and has cycled up to number "125 which is not an mtp device." Is there any way to continue the install?
 The process indicator [the little button thingy that spins inside] indicates the installer is still slogging on trying to find this device.
The skip button is greyed out so I presently have no way of continuing the Lubuntu install.
This is a new install on a re-partitioned hard drive with all but /home and /recovery re-partitioned and formatted. I used gparted initially and then went through the manual partition option in the Lubuntu install program.

My searches for MTP, Mpt probe and MPT probe failure on this site have retrieved no results

Is there a workaround?

This HP 110-220z was running a dual boot Windows 8 and Ubuntu 16 but slogging along on both because the dual processors are only 1.8 Ghz instead of 2.0 or greater. Ubuntu 16.14 kept graying out firefox and Lebri Office windows even with a RAM upgrade to 16 GiB.

The install program has now been stalled for over an hour and a half. The process indicator indicates it is still running, but the Terminal display has not indicated any new activity for a half hour since:

Screen: "Removing Conflicting Operating System Files."
Mar 23 22:09:29 lubuntu kernel ... usb: 6-1 disconnect, device 74
...

"Mar 23 22:27:51 lubuntu mpt probe: checking bus: 6, device: 125 "sys/devices/pci0000/00/0000:00:16.0/usb6/6-1" "
"Mar 23 22:27:51 lubuntu mpt probe: bus: 6, device: 125 was not a MTP device."
When I tried to mark a line to copy a
^C showed up, but the installer has not continued to another screen.

Only option at present seems to try the restart button in the Desktop Popup window.

To eliminate the installation disk created in Win10 I have burned a new Lubuntu 16.10-desktop-amd64.iso from http://cdimage.ubuntu.com DVD created with K3B in Ubuntu,

followed checklist, confirming hash, disk inspection passed,

Lubuntu install fine right up to the "The installation will end soon" screen, over an hour ago.

It is constantly repeating "lubuntu mpt probe: bus: 6, device: xxx was not a MTP device." it tested usb6-1 1 up past 126 and is up to 126 a second time restarting at one and continuing past 9.

This is apparently an endless loop, and will not finish until it finds a MTP usb device. This HP110-220z has about ten usb devices, 3 internal and the rest external ports and apparently none with MTP firmware or the like.

The desktop "restart" menu option is ignored. This will be the second time I have had to ctrl+alt+del out of an almost finished install.
