uhci_hcd and ehci_hcd
Hmmm. Not sure what's going on here.
lsusb sometimes doesn't show the usb tuner stick (Terratec Cinergy XS T DVB tuner) that is obviously plugged in...
I discovered by removing and reinserting various kernel modules it started working again (showing it was not just a loose connection).
What is the difference between the host controller modules uhci_hcd and ehci_hcd and should both be inserted at once?
I found the card started working after just reinserting the uhci_hcd module suggesting the other one is unnecessary AND causes problems.
