The same USB stick has been working fine on T420.

But, on T430, it gives error. Why?

What's T420/T430? We shouldn't have to do research to answer your question.

I believe they are the type numbers of Thinkpad laptops. But then
again, I could be wrong. :)

Lenova laptops favored by some Linux users.
Do other Live Distros on other USB Flash Drives work on the T430?

Go to whatever search engine you favor and
enter in the Search window the Ubuntu (version# error: symbol
'grub_calloc' You may or may not learn anything thereby
but it is free and not snarky.
I use duckduckgo myself for the privacy.

No but someone should mention at least that online research can be done
and how to phrase a query. Heck kids should be learning that in grade
school. It makes an excellent case for an extensive vocabulary
and a good understanding of grammar.

It's possible in your case, that some identifier is confused, and
it's not just booting from the USB stick.

Yes, you're right about T420/T430 being ThinkPad model #. It's a new
T430 and I've only tried U18.04 & U20.04 USB Live. Both failed.
Could it be a BIOS setting ? UEFI ?

Should. I have a Thinkpad L530, same series year but larger screen,
currently running 22.04 but has been running Ubuntu since 12.04

What identifier?

Same HDD, same Ubuntu Live USB stick moved to newly acquired T430.
The only thing I can think of is BIOS. Or, USB bus is bad?

Oh, my.

It's a puzzle. I've not seen this pattern before. This exact pattern.

Instinct tells me, a user recently attempted to use GParted
to do something to his USB. And this is why the partition numbering
is now "funky".

But what ? What was the user trying to do at the time ? The reason
I'm trying to figure that out, is to guesstimate the damage pattern.
Where did the damage go ? What did it do ?

I'm looking at that pattern, and trying to tell what is going on.

I suspect maybe the Live Media being used to take the snapshot,
may have mounted the casper-rw for its own self.

The other part of the picture that cries out for attention, is
the two partitions that are exactly 12.75 GiB. I don't think
one is holding the other. That would not work. It could be
a coincidence, but on computers, these patterns are a "smell".

I would hold off on running "Boot-Repair" on that, until you figure
out how those partitions got out-of-spatial-order. Gparted will
renumber partitions on you, and that will break Grub on one partition
part of the sequence. That's where some information is read from
the ESP and used to find the location of the next stage of grub.
It is probably, at this point, indexing into the wrong partition.

First we have to review the history, the time line, and see
whether meddling with it as it sits now, is a bad idea or not.

If you're bored, make a backup of the stick. Macrium could do that,
since being from Windows, it will not try and mount anything for fun.
It uses smart backup for partitions it knows (FAT32, NTFS, EXTn),
and it will use "dd" for the ones it does not know (like a Microsoft
Reserved 16MB is done with dd as there is no file system).

Partition Name FS Mount Point Label Size Used Unused Flags
/dev/sdb5 primary ext4 /media/xerus/casper-rw casper-rw 12.75GiB 2.42GiB 10.33GiB
/dev/sdb1 primary ntfs /media/xerus/usbdata usbdata 12.75GiB 64.91MiB 12.69GiB msftdata

It would be more normal for the ESP (sdb3) to be laid down first as sdb1.
It's 300MB, a sign that Ubuntu did it, and not a Windows thing.
Windows would use a 100MB ESP, which pisses off other Debians.

The partition numbering appears "wrong by expectation", but what
do I know. These things apparently happen all the time, this
weird stuff. But our job is to tip it upright, without breaking it.

Give us a summary, of the history of the thing, and what you've
tried to do to it since install (like, with Gparted).

I have a new thinkpad X1 Carbon, ordered it preinstalled with Ubuntu. I
had to file a bug report because the "recovery partition" had the same
naming scheme as an ubuntu live usb stick, so booting with the ubuntu
USB stick would somehow cause the system to trigger a recovery of the
OS. I ended up having to mount the recovery partition from another live
USB that wasn't ubuntu-based and rename the directory structure from
/casper/whatever to something else so i could finally boot off the USB
stick to install a 2nd ubuntu version beside the default.

No backup needed. It's just a Live Ubuntu USB Drive With Persistent
Storage created from an .iso file using mkusb. See instructions here...

How to Create a Live Ubuntu USB Drive With Persistent Storage
https://www.howtogeek.com/howto/14912/create-a-persistent-bootable-ubuntu-usb-flash-drive/

I thought the Live Ubuntu USB drive is suppose to be portable until I
ran into this problem.

Why? Seems like there's no rhyme or reason.

That's because I specified to use 50% for user data and 50% for
persistence data.

OK, reproduced a typical Ubuntu persistent live install with mkusb (from their repo).

mkusb 22.0.7 (mkusb-dus)

To be aligned on 1048576 (1MB) boundaries, the numbers need
to *divide* by 1048576. Without grinding each and every number
(hint: they're all wrong), take this as example of "lunatics
on the job"

256000000 bytes

Now, try and divide that by 1048576. Does not divide evenly.
They should have used 256*1048576 if that's what they had in
mind. You have to use the correct one, of MB or MiB.

Flash life will suffer. Because everything is mis-aligned.
This increases the number of write cycles, to do anything,
and can also make it slower (like on a HDD this would be slower).

Plus, to increase the silliness, the Ubuntu ISO is not
padded out to 1048576 multiple either (thank you, Canonical).

A user could do this (I do it occasionally before dd to USB stick),
but the tool should just pad out the ISO to the nearest multiple
of 1048576 bytes.

Partitions are not in spatial order. The risk in this case,
is that some idiot third-party partition manager will "fix this"
without telling you, which would render the device unbootable.

OK, so the next step of the analysis, is to transfer the 256000000
partition, /dev/sda3, into a .img file with dd. This is roughly what
I did. Not a verbatim copy. I use 7ZIP on Win for doing the extraction
easier, but I've also done this on the Linux side.

$ factor 256000000
256000000: 2 2 2 2 2 2 2 2 2 2 2 2 2 2 5 5 5 5 5 5
\-------------------------/
$ sudo dd if=/dev/sda3 of=efs.img bs=16384
$ sudo mount -t vfat -o loop efs.img /mnt

It could be, when this /mnt/boot/grub/grub.cfg gets overwritten
during normal Ubuntu operation. It refers to a variable "$root"
here, but I don't know how such a thing is defined.

Try:

lsusb -tv

both before, and after, the hardware cabling changes.

Look for differences (other than the obvious ones).

There's nothing abnormal there, so far. In terms of behavior, like
something showing up when you expect it to show up.

This is my other machine with the mkusb in it.

*******

Notice how mine has the numbers, like 8087:0024

Yours does not.

This means, somehow, the process to enumerate hardware either
isn't running, or there is an elevation problem (not enough
permissions to read the USB config space).

If you can find a log, maybe there's something in there which
indicates why the devices are not getting read properly.

But at least we can say "it wasn't a power problem". I was thinking,
when I asked for this info, that there would be evidence of the
device "winking out'. And that's not the case. I had to run the same
command on my machine, just to see what mine would look like. You
can see it did get a little snotty about the fourth part of my BT
dongle, but, it did manage to use "0b05:17cb" for all four entries.

And good ole Google, I'm not getting a result for "lsusb missing VID PID".

The thing is, to get as far as your lsusb got, the endpoints to the
USB devices must have formed. Otherwise, the tree view would not
exist. This means, at the physical layer, all the devices connected.
But somewhere in the USB stack (or DBUS or something), there is
a disconnect preventing the USB config space from being read
and parsed. Parsing your scanner for example, would find some
sort of scanner class info.

Libusb keeps the info that lsusb uses.

https://libusb.sourceforge.io/api-1.0/structlibusb__device__descriptor.html

https://github.com/libusb/libusb/blob/master/libusb/libusb.h

enum libusb_error {
LIBUSB_SUCCESS = 0, <=== This is the rc = value thing below

https://github.com/gregkh/usbutils/blob/master/lsusb.c

3539 libusb_get_device_descriptor(dev, &desc); <=== The code chucks away useful info...

And you can see people fooling around with it here. Notice how
they checked for a return code.

https://stackoverflow.com/questions/14722083/how-to-use-libusb-and-libusb-get-device-descriptor

rc = libusb_get_device_descriptor(device, &desc);

The lsusb does not check the return code, and throws it away.

Since this is userland stuff, you can:

1) Go to synaptic and edit the repostories and click the "source repository".
2) Make sure build-essentials package is installed (has a compiler for example).
3) Follow a recipe for building code from source on Ubuntu.
4) You can then edit the source, change the code to look like this. Then recompile.

int rc;

rc = libusb_get_device_descriptor(device, &desc);

if (rc != 0) printf("got a RC of %d for libusb_get_device_descriptor\n", rc);

Anyway, I know you're not going to do that, so that's... just an idea.

I'm sure that the logic of the lsusb.c does cleverly cover off this situation,
in an indirect way, but I would prefer to see the error printed immediately
when there's a problem. There really isn't a very rich vocabulary for
the rc= errors in this case.

LIBUSB_SUCCESS = 0,
LIBUSB_ERROR_IO = -1,
LIBUSB_ERROR_INVALID_PARAM = -2,
LIBUSB_ERROR_ACCESS = -3,
LIBUSB_ERROR_NO_DEVICE = -4,
LIBUSB_ERROR_NOT_FOUND = -5,
LIBUSB_ERROR_BUSY = -6,
LIBUSB_ERROR_TIMEOUT = -7,
LIBUSB_ERROR_OVERFLOW = -8,
LIBUSB_ERROR_PIPE = -9,
/** System call interrupted (perhaps due to signal) */
LIBUSB_ERROR_INTERRUPTED = -10,
LIBUSB_ERROR_NO_MEM = -11,
LIBUSB_ERROR_NOT_SUPPORTED = -12,
LIBUSB_ERROR_OTHER = -99

*******

Summary: While you might thing I was stupid for going through that path,
the bread crumb from the above, gives me this. Try running
sudo lsusb -tv and see if the detail printed is better.

https://stackoverflow.com/questions/40597515/libusb-calls-without-sudo-using-udev-rules

Mow, looking at that discussion thread, does Ubuntu use udev ? And if so,
would yours be subtly screwed up ?
