thekx Posted January 12, 2007 Report Share Posted January 12, 2007 Hi, I'm getting occasional kernel panics from my Leadtek Winfast DTV dongle, which leave it in an unusable (locked) state. 'service hotplug restart' seems to do a warm reset - not enough to help here. Equally, a system reboot doesn't fix it. I have to pull the USB connection, or poweroff and disconnect the power to the PSU. The system box isn't very accessible, so I'd really like to find a gentler alternative... So, is there any way in software to hard reset USB devices? I can tolerate resetting the whole USB subsystem if it fixes this. I've tried googling, but either there's no easy answer, or I'm like a n00b and missing the magic search terms. Best, Nick Quote Link to comment Share on other sites More sharing options...
arctic Posted January 12, 2007 Report Share Posted January 12, 2007 You could try to launch /etc/init.d/udev restart /etc/init.d/usb restart /etc/init.d/haldaemon restart /etc/init.d/hotplug restart in that order. Perhaps it helps. Quote Link to comment Share on other sites More sharing options...
thekx Posted January 14, 2007 Author Report Share Posted January 14, 2007 Thanks arctic. Now I've had a bit of free time I've managed to provoke the kernel panic, and tried your suggestions. None of them even provoked a line in syslog, and the blue LED on the DVB stick stayed lit all the way through. Bummer. Oddly, I don't even have hotplug as a service in /etc/rcX.d Plan B is, I guess to try to get the kernel panic fixed. I guess I'll try to find an appropriate list to post on for v4l-dvb...

scarecrow Posted January 14, 2007 Report Share Posted January 14, 2007 Hotplug has been obsoleted in almost all distributions since a long time ago... Quote Link to comment Share on other sites More sharing options...
thekx Posted January 15, 2007 Author Report Share Posted January 15, 2007 Thanks scarecrow, that explains that. Tracking what gets dropped across versions isn't easy unless it's something you're using daily... Quote Link to comment Share on other sites More sharing options...
