I have Gentoo AMD64 2005.0 with kernel 2.6.11-gentoo-r10 running on an MSI K8N Neo4 nForce 4 Ultra Platinum motherboard. I tried two different USB memory sticks. The first is recognized by the kernel with no problems. dmesg reports the following.

It evidently is USB 1.1 (OHCI). The second is not recognized. dmesg reports the following.
| Code: | usb 1-2: new high speed USB device using ehci_hcd and address 6
usb 1-2: khubd timed out on ep0in

The second is evidently USB 2.0 (EHCI). dmesg seems to indicate that things are OK with EHCI.
| Code: | ehci_hcd 0000:00:02.1: EHCI Host Controller
PCI: Setting latency timer of device 0000:00:02.1 to 64

lspci -v reports the following.
| Code: | 0000:00:02.1 USB Controller: nVidia Corporation CK804 USB Controller (rev a3) (prog-if

Does anyone have any insights into what might be wrong?
Edit: USB 2.0 (ehci_hcd) now works flawlessly with the 2.6.12-gentoo kernel.  |
