http://bugzilla.opensuse.org/show_bug.cgi?id=1092839 Bug ID: 1092839 Summary: brltty hogs USB serial ports without obvious way to disable Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Other Assignee: bnc-team-screening@forge.provo.novell.com Reporter: afaerber@suse.com QA Contact: qa-bugs@suse.de CC: lnussel@suse.com Found By: --- Blocker: --- On Leap 15.0 certain /dev/ttyUSBx devices are not showing up as expected. For example, I attach a hub with e.g. two USB UART adapters: Bus 004 Device 012: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP2102/CP2109 UART Bridge Controller [CP210x family] Bus 004 Device 011: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP2102/CP2109 UART Bridge Controller [CP210x family] but there's only a /dev/ttyUSB0 and no /dev/ttyUSB1. This appears to be related to brltty, because "zypper rm brltty" and re-plugging the hub fixes the issue. However, brltty appears to come back with the next "zypper dup", so it's no permanent fix. The actual brltty@foo service instance cannot be stopped either. The accessibility pane in GNOME Control Center does not appear to offer any options to disable this behavior. No related YaST module that I can spot either. Can we please get sane defaults again like in 42.3 and only activate such destructive accessibility services when explicitly requested by the user? -- You are receiving this mail because: You are on the CC list for the bug.
