[SOLVED] - USB mayhem/failure after mythtv install
I boot up and
toad@deskarch 992\3 ~ > lsusb
Bus 005 Device 002: ID 0ccd:0038 TerraTec Electronic GmbH Cinergy T^2 DVB-T Receiver
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hubI want to watch TV using my DVB-T receiver and it is not found 
I unplug the little devil and check dmesg:
usb 5-2: USB disconnect, address 2
dvb-usb: bulk message failed: -22 (2/-1)And from then on whatever I plug into usb does not work. It is as though my usb ports are dead. However, the little lamp on the DVB-T receiver is lit and my usb-keyboard continues to function.
If I do lsusb in the terminal it just sits there and does nothing. CTRL+C ends in:
toad@deskarch 980\9 ~ > lsusb
^C^C^C^C^CThe terminal is basically lost.
Thing is, I cannot do without USB and I cannot do without Arch...
HELP!!!
EDIT:
Okay, I changed the signature 'cos I found out about the culprit: mythtv. I took the daemon out of my rc.conf and everything is working again as advertised - apart from mythtv which never worked. Time to get on that mythtv irc channel...

Re: [SOLVED] - USB mayhem/failure after mythtv install
Some more info:
I unplug the receiver, do a dmesg and get the following:
INFO: task khubd:1376 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
