I recently bought an ALi usb 2.0 pci card and a usb 2.0 iomega super dvd drive. However, ehci-hcd doesn't appear to be recognizing the device as usb 2.0, while usb does. I'm using fedora core 2 with the 2.6.8-rc2 kernel. I've attaced the output of /proc/bus/usb/devices. Here's the relevant snips from dmesg of what happens when I plug the device in: hub 1-0:1.0: port 5, status 0501, change 0001, 480 Mb/s hub 1-0:1.0: debounce: port 5: total 100ms stable 100ms status 0x501 hub 1-0:1.0: port 5 not reset yet, waiting 50ms ehci_hcd 0000:02:08.3: port 5 full speed --> companion ehci_hcd 0000:02:08.3: GetStatus port 5 status 003801 POWER OWNER sig=j CONNECT ohci_hcd 0000:02:08.2: wakeup ohci_hcd 0000:02:08.2: GetStatus roothub.portstatus [0] = 0x00010101 CSC PPS CCS hub 4-0:1.0: port 1, status 0101, change 0001, 12 Mb/s hub 4-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x101 ohci_hcd 0000:02:08.2: GetStatus roothub.portstatus [0] = 0x00100103 PRSC PPS PES CCS usb 4-1: new full speed USB device using address 3 usb 4-1: not running at top speed; connect to a high speed hub usb 4-1: new device strings: Mfr=0, Product=1, SerialNumber=2 usb 4-1: default language 0x0409 usb 4-1: Product: 'IOMEGA USB 2.0 DEVICE' usb 4-1: SerialNumber: 00118842400000021425
It looks like you just have to do what the message says:
usb 4-1: not running at top speed; connect to a high speed hub
It should be enough to connect the device to a different port.
