libusb_get_device_speed() does not work for
libusb_wrap_sys_device() devices in v1.0.23.

See qemu reproducer and workaround patch.

libusbx-1.0.23-3.el8.x86_64

3 patches fixing this

Here are 3 patches for libusb which I have just posted upstream.

The first patch fixes this, the other 2 are some changes to one of the examples programs to allow testing wrapped-fds with that example, allowing easy testing of the fix.

Comment 5 RHEL Program Management 2022-02-24 07:27:15 UTC
After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
