I just wanted you to know that you are not alone with this problem. I've seen the same symptoms on my parents machine during the last 1-2 months --> ie. keyboard hangs completely, mouse works and the host either hangs completely sooner or later with only the following usb debug messages in the logs (pasted below).
I believe that there is certainly some sort of bug in cinergyT2-driver as I've not seen the hang happen whenever the cinergyT2 usb-receiver has been disconnected from the machine.
Host configuration is: 2.6.22-rc4-git4 kernel + latest DVB drivers from v4l-dvb tree (previously also tested with FC6 kernels with same symptoms) MythTV-software (from devel SVN)
Asus P4P800-E motherboard (ich5 & PDC20378 sata-controllers) 1GB ram Intel P4 2.8MHz Terratec Cinergy T2 dvb-t receiver
