When mounting external HDDs on my Dell 1720, I get these messages in my
log, regardless of what port I use:

Jan  7 23:54:54 karl kernel: [14778.504269] usb 5-1: new full speed USB
device using uhci_hcd and address 4
Jan  7 23:54:54 karl kernel: [14778.647522] usb 5-1: not running at top
speed; connect to a high speed hub

I've looked in Google, and the info there suggests that high speed
devices are handled by a module called ehci_hdc. I have looked through
my entire system and can find no such module anywhere. Further Googling
suggests that this functionality is no longer handled by loadable
modules, but is compiled in. BTW, I know the ports I am using are
2.0-capable.

lsusb output looks like this:


Bus 002 Device 003: ID 0c45:63e0 Microdia 
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 004: ID 046d:c01a Logitech, Inc. M-BQ85 Optical Wheel Mouse
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 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 011: ID 067b:2506 Prolific Technology, Inc. 
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

So - does anyone have high-speed (USB 2.0) USB devices working with
Jaunty and if so what did you do to make them work?

Regards, K.
