            Bug ID: 216282
           Summary: usb-mass storage
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.15.0-41-generic
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: audioprof2001@yahoo.com
        Regression: No

since Groovy Gorilla, maybe older...

problem #1.
 usb mass storage,
delay time is too fast, and there is No .conf in /modprobe.d
i have to unplug and plug again the external usb hdd cable turned-on
so Linux can detect the HDD and mount.

ASM1051 is detected with $ lsusb
when i turn-on, 
but the HDD is Not Detected, because delay time is too fast/short.
its like turning-on without a HDD.

upgraded the firmware of the external USB IC controller to latest.
https://github.com/juanpc2018/Asmedia-AS2105-sata-to-USB-3

because large HDDs "over 2TB" was Not working,
Now works ok exept that problem in Linux.
Windows8.1x64 works OK.

problem #2.
Linux detects a different speed?.
$ lsusb
Bus 002 Device 004: ID 174c:5106 ASMedia Technology Inc. ASM1051 SATA 3Gb/s
bridge

is Not 3Gb/s = 375MB/s.
is 5Gb/s = 550MB/s
when used with SSD,
large 18TB HDD are 250MB/s.

there is something strange going on with usb-mass-storage.

--- Comment #1 from Alan Stern (stern@rowland.harvard.edu) ---
What delay time are you referring to?

What speed does Linux detect?

What does "lsusb -v" show for this drive?

What shows up in the dmesg log when the HDD is detected and when it is not
detected?

In your lsusb output, where it says "ASM1051 SATA 3Gb/s bridge", that 3Gb/s
speed is not what Linux detects; it is part of the device's product name.

[Bug 216282] usb-mass storage

[bugzilla-daemon]

https://bugzilla.kernel.org/show_bug.cgi?id=216282

--- Comment #3 from audioprof2001@yahoo.com ---
When you Turn-on the USB3.0 to SATA controller,
electrons travel near the speed of light.

Kernel interupts the CPU very fast, betwenn 1GHz and 2.8Ghz
to detect & load drivers.

BUT... the Mechanical HDD needs time to spin-up, when is turned-on,
time to reach operating speed of 7200rpm,
Large 3.5" HDD eat more than 3Amps at 12volts dc to spin-up.

USB Mass Storage Needs a Delay, an interrupt wait to read from the controller,
wait to initialize, until HDD had enough time to spin-up and read basic info,
like Name, File system, etc...

Like the Turtle vs. Rabbit Tale.

Serial number 00001,
its the same enclosure type TT BlacX, i have 2 same,
but 0001 has an SSD Crucial MX500
reads 440MB/s
using gnone-disks benchmark
because its a cheap TLC, but Not as cheap as the BX500 with No ram.

serial 0002 has the mechanical 3.5" HDD.

--- Comment #8 from Alan Stern (stern@rowland.harvard.edu) ---
Some of the things you wrote above are not correct.  "When you Turn-on the
USB3.0 to SATA controller, electrons travel near the speed of light."  Not true
at all; electric waves travel near the speed of light but the electrons
themselves move at only a few centimeters per second (bulk motion).

Anyway, the information you reported doesn't indicate what's going wrong.  I
don't think it's simply a matter of waiting for the disk to spin up; the
commands sent by the kernel have a 30-second timeout and that should be plenty
of time.

A usbmon trace of a non-working connection should help.  Before you plug in the
USB cable, do:

   cat /sys/kernel/debug/usb/usbmon/2u >mon.out

Then after the drive has been plugged in and the drive has failed to appear,
kill the "cat" process with ^C and attach the mon.out file to this bug report.

In fact, you might want to do this twice: once where the drive doesn't work,
and once where it does work, for comparison.

Your system probably didn't mount debugfs for you.  You'll have to do:

   mount -t debugfs none /sys/kernel/debug

first.

I don't understand that error message.  Regardless, what you want is the
directory on which a debugfs filesystem is mounted.  On my system that's
/sys/kernel/debug:

$ mount
...
debugfs on /sys/kernel/debug type debugfs
(rw,nosuid,nodev,noexec,relatime,seclabel)

Maybe you need to change the command line to:

   mount -t debugfs debugfs /sys/kernel/debug

Or maybe debugfs is already mounted somewhere else.  Or maybe your kernel was
built without support for debugfs.

The question is which directory or file on that path is missing.  From comment
13, it looks like /sys/kernel/debug/usb should exist.  Maybe it doesn't have a
usbmon subdirectory because the usbmon module hasn't been loaded.  If you do:

   modprobe usbmon

it should create that directory and the 2u file within it.

im using another Linux, same usb problem, 
but in this linux
$ sudo mount -t debugfs debugfs /sys/kernel/debug

is mounted in /syskernel/debug ok

i can see inside /sys/kernel/debug
with sudo

$ sudo modprobe usbmon
works
$ sudo cat /sys/kernel/debug/usb/usbmon/2u >mon.out

creates a directory in /sys/kernel/debug/usb
called /usbmon

but nothing happens all files inside are 0kb.

[Bug 216282] usb-mass storage

--- Comment #19 from Alan Stern (stern@rowland.harvard.edu) ---
Make sure your current directory is something regular, like your home
directory. Not something under /sys/ -- those directories aren't writeable.

It's normal for the files under /sys to show up as 0 bytes long in an "ls -l"
listing.  They aren't real files, but interfaces to the kernel.  As long as
they do show up at all they should be okay.

While the "cat" process is running, any activity on the USB bus (such as
activity caused by plugging in the drive) will get copied to the "mon.out"
file.

(By the way, the output from neofetch is not really useful.  You might as well
stop including it.)

It looks like you may be right about the initial time delay being too small.  I
don't see any significant differences in the usbmon trace between the initial
plug-in and the later one, except that the device failed to respond during the
initial plug-in when asked to identify itself.

(You can compare them yourself just by looking at the trace file.  The initial
plug-in is detected at line 7, and the second plug-in is detected at line 193. 
The lines subsequent to those are virtually identical if you ignore the first
two columns, with just one or two unimportant differences -- up until the
failure at line 75.)

You can change the length of the time delay by setting the usb-storage
delay_use parameter.  For instance, assuming that the usb-storage module is
already loaded, do:

   echo 20 >/sys/module/usb_storage/parameters/delay_use

before you plug in the drive.  That will change the delay to 20 seconds (the
default delay value is 1 second).  Maybe it will help.

1 Fail, yes..
...
4 worked 1x time, because did not waited for hdd platter to stop before

...
10 works but probably more is required for 20TB.
The heavier the platter = more time.

Large HDDs "fail" because are sealed with Helium,
has gas leak,
was Not filled enough at factory,
does Not-pass Quality Control.

= more spin-up time,
