FWIW, the problem did occur with two RTL2832U from different manufacturers (one E4000 one R820T, both from NooElec), plugged directly into a USB port on a System 76 laptop (no hub involved), and persisted over multiple reboots. It was only reverting that patch that made it work at all. The segfault makes sense, since the patch has the library detect a transfer error that used to be ignored and then set a flag that inhibits the wait for in-progress asynch actions to complete before shutting down: AFAICT libusb1 is known to get upset when this happens. I'm guessing the error was transient or diagnostic of some other condition, and should not have been taken as a sign that the device had gone away and the library should shut down. lemur4[3]$ dpkg-query -s libusb-1.0-0 Package: libusb-1.0-0 Status: install ok installed Multi-Arch: same Priority: optional Section: libs Installed-Size: 108 Maintainer: Ubuntu Developers <ubuntu-devel-discuss(a)lists.ubuntu.com> Architecture: amd64 Source: libusb-1.0 Version: 2:1.0.9~rc3-2ubuntu1 Depends: libc6 (>= 2.14) Pre-Depends: multiarch-support Description: userspace USB programming library Library for programming USB applications without the knowledge of Linux kernel internals.
