It seems that my problem is fairly close to the original poster who says: ...and it seems as though the USB bus is dead. The only way to get it working again is a reboot...
I would be happy to file a different bug report, but the problem seems related to the bus going dead, not the specific USB peripheral. -- usb wireless device zd1211rw 5-2:1.0: zd_chip_control_leds error -19 https://bugs.launchpad.net/bugs/74362 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
