The dot in the kernel name of a USB device indicates that a device is connected via a hub. In theory, this can even be cascaded, leading to names like "2-1.2.1.3.4" So the hardware difference is that the ports in the Toshiba are not 'primary' but exposed through an internal hub as opposed to the Dell. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1866926 Title: usb_modeswitch does not switch modems (remain visible as mass storage) Status in usb-modeswitch package in Ubuntu: Confirmed Bug description: After upgrading to Ubuntu focal fossa development branch the usb_modeswitch does not seem to work any more on a Toshiba laptop.

[Desktop-packages] [Bug 1866926] Re: usb_modeswitch does not switch modems (remain visible as mass storage)
To further clarify the impact of different hardware on bug occurrence:
The difference in Mariusz' hardware (Dell vs. Toshiba) leads to
different kernel names ("3-4" on Dell vs. "2-1.2" on Toshiba). So
"device validation" only happened on his Toshiba (thereby updating iface
to the wrong value of 8), but not on Dell. Similarly, I had a problem on
RPi 3 (kernel_name = "1-1.3") but no problem on an x86_64 VM
(kernel_name = "1-1"). My hardware and VM both ran on Ubuntu 20.04 LTS.
This is the commit that fixed a segfault in the C dispatcher but
introduced the problem for Mariusz and me:

[Desktop-packages] [Bug 1866926] Re: usb_modeswitch does not switch modems (remain visible as mass storage)
I am likely experiencing the same issue, yet on other hardware: Ubuntu
20.04 with a ZTE MF100 modem but only on Raspberry Pi. The good news: I
have triaged the issue.
The bug is in "usb_modeswitch_dispatcher.c", a C rewrite of the upstream
Tcl script. The C dispatcher receives the modem's kernel_name. If it
contains the characters dot ('.') and dash ('-') but no colon (':'), the
device is marked for some extended "interface validation" (see lines
343ff of "usb_modeswitch_dispatcher.c"). A bit further down at lines
388ff, the "iface" is initialized to 0, but the interface validation
updates it to 8. The value 8 stems from an atoi() invocation on the
contents of "bInterfaceClass". For this updated iface value, the C
dispatcher tries to find the corresponding (sub) interface directory and
this fails because my modem does not have 8 sub devices. Until here,
18.04 and 20.04 behavior is identical. However, the following new code
was introduced in 20.04 right after the directory lookup attempt is
made:
--8<--
if (ifdir == NULL) {
modeswitch_log(" No access to interface %d. Exit\n", iface);
return 1;
}
--8<--
This is causing the early exit for Mariusz and me. If I remove this
code, the rest of the C dispatcher works fine (even with a wrong iface
value of 8 - this is the same behavior as it was on 18.04). In a
scenario where no interface validation takes place (e.g. because of a
colon in the kernel_name or the absence of a dot - such as Ubuntu 20.04
on x86_64 VM), the iface value of 0 remains unchanged and the interface
directory is looked up successfully.
I have tried to match the C dispatcher code with the upstream Tcl
script. The Tcl script initializes iface to 0 and eventually updates it
to "1.0" when doing the interface validation branch.
Another thing that I noticed is that the C dispatcher erroneously uses
atoi() on the contents of bInterfaceClass. The content is a hexadecimal
string such as "00", "08" or "ff" while atoi() expects a decimal string.
If bInterfaceClass contains "ff", atoi() would return 0.
I have solved this problem by replacing "usb_modeswitch_dispatcher" with the
upstream Tcl script, pointing its interpreter to jimsh and installing jimsh. I
think it would be a wise choice to ditch the C dispatcher, use the upstream Tcl
script and make the package depend on jimsh. Reasons:
- The C dispatcher does not implement the same functionality as the Tcl script
in 2.5.2.
- Implementing changes from the Tcl script in 2.6.0 would be even more painful.
- The usb_modeswitch author provides flavors that eliminate the Tcl dependency.
- I fail to see how the "binary size" argument still applies in 2020 to
machines that are capable of running Ubuntu.

Without being familiar with the Ubuntu flavour of usb_modeswitch - can this be a permission issue? Does the usb_modeswitch wrapper and program run in the proper user / group context?

There is no SCSI attribute named ref but there is one named rev. This is likely to be a typo from ubuntu rewrite of the original usb_modeswitch_dispatcher.tcl which reads the rev attribute. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1866926 Title: usb_modeswitch does not switch modems (remain visible as mass storage) Status in usb-modeswitch package in Ubuntu: New Bug description: After upgrading to Ubuntu focal fossa development branch the usb_modeswitch does not seem to work any more on a Toshiba laptop.
