Hi All, I have the PCTV nanostick solo. This works perfectly, but when I pull out the stick while i'm watching TV, the driver crashes. When I replug the stick, there's no reaction in dmesg. To reproduce: 1)plugin the stick 1a)scan channels with scan, see also https://wiki.archlinux.org/index.php/Digitenne#Configure_Sasc-ng 2)use tzap, cat and mplayer to watch TV 3)unplug the stick 4)watch the fireworks in /var/log/everything.log (dmesg) See below for details. I run the following kernel: Linux cedric 2.6.39-ARCH #1 SMP PREEMPT Mon Jun 6 22:37:55 CEST 2011 x86_64 Intel(R) Core(TM)2 Duo CPU T5670 @ 1.80GHz GenuineIntel GNU/Linux Best regards, Cedric 1)plugin the stick. This yields the following messages in dmesg: [75262.399219] usb 2-4: new high speed USB device number 4 using ehci_hcd [75263.442900] IR NEC protocol handler initialized [75263.585643] dib0700: loaded with support for 20 different device-types [75263.586003] dvb-usb: found a 'Pinnacle PCTV 73e SE' in cold state, will try to load a firmware [75263.600941] IR RC5(x) protocol handler initialized [75263.626257] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.20.fw' [75263.626871] IR RC6 protocol handler initialized [75263.825852] IR JVC protocol handler initialized [75263.830658] IR Sony protocol handler initialized [75263.841488] dib0700: firmware started successfully.
