This is the problem I'm talking about. No errors, no new devices on the hub, no nothing appens at this point. No idea how to fix this. > o Disconnect hub from motherboard: > > # tail -f /var/log/messages > Sep 28 17:21:44 foobar kernel: usb.c: USB disconnect on device 2 > Sep 28 17:21:44 foobar kernel: usb.c: USB disconnect on device 4 > Sep 28 17:21:44 foobar /sbin/hotplug: invoke /etc/hotplug/usb.agent > Sep 28 17:21:44 foobar /sbin/hotplug: invoke /etc/hotplug/usb.agent > > o Re-connect hub to motherboard: > > # tail -f /var/log/messages > Sep 28 17:22:28 foobar kernel: hub.c: USB new device connect on bus1/2, > assigned device number 5 > Sep 28 17:22:28 foobar kernel: hub.c: USB hub found > Sep 28 17:22:28 foobar kernel: hub.c: 4 ports detected > Sep 28 17:22:28 foobar /sbin/hotplug: invoke /etc/hotplug/usb.agent > Sep 28 17:22:28 foobar /etc/hotplug/usb.agent: ... no drivers for USB > product 451/2046/125 > Sep 28 17:22:28 foobar kernel: hub.c: USB new device connect on bus1/2/3, > assigned device number 6 > Sep 28 17:22:28 foobar kernel: usb-uhci.c: interrupt, status 2, frame# 349 > Sep 28 17:22:28 foobar kernel: usb.c: USB device not accepting new address=6 > (error=-110) > Sep 28 17:22:28 foobar kernel: hub.c: USB new device connect on bus1/2/3, > assigned device number 7 > Sep 28 17:22:28 foobar kernel: usb-uhci.c: interrupt, status 2, frame# 559 > Sep 28 17:22:28 foobar kernel: usb.c: USB device not accepting new address=7 > (error=-110) While this problem can be fixed by Georg's latest patch (not very elegant, but solves this nevertheless and the device is working OK after a hub replug). > o Obviously, in neither case was the camera working after > disconnect/re-connect of the hub. > > o Can do more testing a little later.
