https://bugzilla.suse.com/show_bug.cgi?id=1217291 Bug ID: 1217291 Summary: Kernel 6.6 regression: Wacom tablet detected as USB hub Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: lbeltrame@kde.org QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- I own a Wacom Tablet One 12 which is supported by libwacom. $ lsusb # From kernel 6.5 Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 004: ID 056a:03cf Wacom Co., Ltd Wacom Billboard Bus 003 Device 003: ID 056a:03ce Wacom Co., Ltd Wacom One pen display 11.6" Bus 003 Device 002: ID 056a:03cd Wacom Co., Ltd WACOM One 12 HUB With kernel 6.6 hitting Factory, the tablet works as a display (it has an integrated display) but it is no longer detected by libwacom-tools and does nto function as a tablet. dmesg only reports, when plugging it in, [ 3.081943] usb usb4: New USB device found, idVendor=1d6b, idProduct=0003, bcdDevice= 6.05 [ 3.081949] usb usb4: New USB device strings: Mfr=3, Product=2, SerialNumber=1 and lsusb, unlike the output above, only shows a USB hub. When downgrading to the latest 6.5 kernel, the tablet is fully functional again. My tests were carried under Wayland (Plasma), but I assume the issue will be on X11 as well, as the issue seems at a lower level. Hardware information: Lenovo Thinkpad X470 The tablet is connected with a single USB cable through the Thunderbolt port. I will test later with the three-way cable Wacom supplies (with an external power supply). -- You are receiving this mail because: You are the assignee for the bug.
