Based on some review from Lonnie Abelbeck, if get_sysfs_name() failed in
get_vendor_product_with_fallback(), the strings "[unknown]" would not be
properly set for the product/vendor.
Now the odds of that happening are very slim, but simplify this all by
setting the strings first, and then, if we can find a real override, use
that instead.

Previously the -v output would not show the vendor/product names if they
were not in the hwdb. Change that to look in sysfs as well if the
database does not have a string, as that's what the non-v version does.

Honor system libdir and includedir
|
|
In commit 8a80f70a8afb ("names.c: if a string can not be found in the
usb.ids file, return [unknown]"), the logic for determining the vendor
and product for the USB device was changed to ONLY rely on the usb.ids
file, instead of falling back to any vendor/product strings that are on
the device itself.
This had the bad side-affect of causing many devices that previously
showed vendor/product information just fine, to now show up as
[unknown].
Fix this up to fall back to looking at the string in the device itself,
and ONLY if the string is not present, will '[unknown]' be printed out.
This changes the output on one of my machines from:
Bus 003 Device 002: ID 32ac:0002 [unknown] [unknown]
to:
Bus 003 Device 002: ID 32ac:0002 Framework HDMI Expansion Card
This should resolve github issue #177, many thanks to the people
reporting it quickly there.

For the output of 'lsusb -t' if a driver is not bound to an interface,
the result looks odd. Fix that up by printing out "[none]" instead.
This changes the output of a line that previous looked like:
|__ Port 004: Dev 006, If 0, Class=[unknown], Driver=, 12M
to be:
|__ Port 004: Dev 006, If 0, Class=[unknown], Driver=[none], 12M

For interfaces or other USB strings, if they are not in the current
hardware database, return "[unknown]" to give people a chance to
understand why their device isn't reporting anything for those fields.
This changes the output of a line that previous looked like:
|__ Port 004: Dev 006, If 0, Class=, Driver=, 12M
to be:
|__ Port 004: Dev 006, If 0, Class=[unknown], Driver=, 12M

Most distros put usb.ids in /usr/share/hwdata/ now, so add that as a
default search path to make working with the script directly out of the
source directory easier. This does not change the ability for the build
system to add their own default path, so distros should not have any
functional change at all.

Some interfaces/devices can not do wakeup at all, and the script will
crash if it runs into them. Handle this properly by reporting
"unsupported" if the file can not be read from sysfs, as that is what
this means.

Not all USB devices have interfaces. This is true in particular of
the STMicroelectronics STEVAL-USBC2DP Type-C to DisplayPort adapter,
as well as possibly other USB-C devices.
As a result these devices do not show up in the output from "lsusb -t",
because the logic in print_tree_dev_interface() lists interfaces, not
devices (as implied by the function's name). This means that the
output from "lsusb -t" can be inconsistent with the output from
"lsusb", since some devices are omitted.
To fix the problem, we make the subroutine call print_usbdevice() at
least once even if the device has no interfaces, and make the latter
routine print a minimal description of such devices (anything that does
not require access to the interface descriptor).

lsusb shows values in 3 digit fields, so do the same for 'lsusb -t' as

|

While dumping descriptors of a USB hid device, I saw a weird line:
'Report Descriptor: (length is -1)'
This is because variable 'n' is used to hold a potential negative
integer value even though it's an unsigned int type in function
dump_hid_device. When usb_control_msg() fails, overflow happens.
It will always pass the 'if' statement below and call dump_report_desc(),
where this weird line finally shows up.
To fix it, an int type should be used to avoid overflow.

Add more status information for SuperSpeedPlus hubs by using the
EXT_PORT_STATUS request to determine the actual link speed ID and number
of lanes that the hub reports it is connected with. This is needed to be
able to figure out the actual connection speed for SuperSpeedPlus
devices.
This requires parsing the BOS prior to the hub information, since we can
only use EXT_PORT_STATUS if the device actually has a SuperSpeedPlus
device capability.
Also fix some issues with the SuperSpeedPlus device capability parsing -
the speed attribute and speed ID counts were off by one, and the minimum
functional speed information is now parsed out.

When recursing into a long USB tree, the local variables in the
print_device() function would get confused and take on the value of the
previous device it printed. This caused devices to not get printed out
at all, the exact opposite of what we wanted.
Resolve this by using the non-POSIX 'local' variable declaration.

lsusb: don't complain on EAGAIN
|
|
Given the requested decriptors are optional, seems like lsusb
should NOT use perror() to communicate why it can't get
the descriptors in question (output is directed to stderr, not stdout).
Further, if we were told to "come back later" (EGAIN),
then it's really not an error.
Only emit this output when user adds "-vv" to the command line.

Found by static analysis:

Therefore, if value is set to 6, the condition evaluates to true and

When running with -v, we previously populated these strings only if we
were able to open the device and query the string descriptors directly.
However, these three values are also reported by the kernel as
world-readable files in sysfs. By querying those instead (using the same
function that already existed for querying fallback vendor and product
names), we can populate these values even for unprivileged users.
These sysfs properties have existed since at least 2005, so I think it's
quite unlikely that this change will regress existing users. However, if
it turns out to, we can always add back the old logic as a fallback when
sysfs isn't available.

commit dddb696e0172 ("lsusb: Read unkown names from sysfs device desc.")
introduced a fallback option for vendor and product names in device
summary lines, fetching them from sysfs when the VID/PID are not present
in udev hwdb. However, it applied this new logic only to summary lines
listing multiple devices (i.e. not -D mode, which only lists a single
device). Refactor the logic into a common function and use it in both
places.

commit dddb696e0172 ("lsusb: Read unkown names from sysfs device desc.")
added code to query a device's self-reported vendor and product names
from sysfs in the case where no names were present in the udev hwdb.
However, as far as I can tell that code was and still is totally broken
for any device that isn't directly under a root hub: this is because it
uses the libusb_get_port_number() function, which only returns the leaf
port number, but treats the returned number as if it's a full device
path.
For example, when trying to query sysfs for the device 2-8.3 (a device
on Port 3 of a hub that's on Port 8 of Bus 2), it will instead
erroneously query device 2-3, ignoring the first hub altogether. This
results in nonsensical output from lsusb, such as a device identified as
a "Bose Corp. Steam Controller".
To fix the issue, use the libusb_get_port_numbers() function to get a
full list of port numbers from the root and use that to construct the
proper dotted devpath. Additionally, special case root devices, which
have the sysfs name "usbN", where "N" is the bus number. Thanks to Tian
Yunhao, who submitted a different fix for this same issue, for spotting
that last piece.

This function was added to names.c by commit dddb696e0172 ("lsusb: Read

there: sysfs is an entirely different data source from the udev hwdb
that names.c works with, and this function both does things (like
directly accessing files) that other functions in names.c don't and
doesn't do things (like depending on the work done by names_init()) that
those other functions do.

Revert "Require newer version of libusb"
|
|
This partially reverts commit 3fe9f89 of usbutils and
updates the usbhid-dump submodule to 209c2b0, which works
around possibly missing libusb_set_option() in older
versions of libusb and thus does not require libusb 1.0.22.
However, lsusb.c itself relies on libusb_get_port_number()
since dddb696 which was added in libusb 1.0.12. Furthermore
the enum values declaring the various debug levels have
changed to their current state in libusb 1.0.13. This version
temporarily fixed a typo in struct libusb_config_descriptor
which was reverted in 1.0.14 again.
So to sum up the previous version check for 1.0.9 in usbutils
previous to 3fe9f89 was wrong and we should test against 1.0.14
instead.
This change was tested against libusb 1.0.14 built from source.

lsusb: Read unkown names from sysfs device desc.
|
|
lsusb tries to get the names for manufacturer and product of a device by
asking the udev hwdb for the names of the device id.
Not every manufacturer and device are in this database. Most devices
however provide those names in the standard USB descriptors, namely
iManufacturer and iProduct.
To get those with libusb we would have to open the device which
requires superuser privileges. To get those values anyway the kernel
provides them in sysfs.
