Knoppix 4.02 doesn't recognize USB port

[klifnor]

In attempting to add a new DVD writer to my system, I find that the V2.0 USB port on the USB card is not recognized by Knoppix 4.02 CD.

The USB data is as follows; the first three items are recognized, but the V2.0 port, which is what I want to use, is not. usbview does not list the V2.0 port, although it lists the three V1.0 ports, all of which function.

Thanks for any suggestions.

Try "sudo modprobe ehci-hcd" and see with "dmesg" if it's recognized.

Thx for the suggestion. The driver wasn't installed. For anyone who has a similar problem, with root privileges do:

insmod /KNOPPIX/lib/modules/2.6.12/kernel/drivers/usb/host/ehci-hcd.ko
