I plugged a Pinnacle pctv 50e USB tv card. It works correctly, I was trying it. After a while, I disconnected it and after very few seconds I plugged an external USB hard drive. For a couple of minutes, USB hub seemed to be not working. No messages on dmesg indicating a new device (usually /dev/sda, I have all the modules for that.) After about two minutes, the USB hub woke up (/dev/sda created, USB mouse working) and on syslog and on every terminal on my desktop appeared some messages.
