I have 3 USB devices: a disk, a camera, and a hub. If I plug the disk and the camera into the USB ports on the motherboard, both devices work fine. If I plug the hub into the motherboard, and the other devices into the hub, they are not detected (although the hub is). The devices were detected correctly (connected to the hub) in beta3.
We just tested with a newer kernel than what went into wolverine (2.4.1-0.1.13) and it worked for us. When we make available a newer kernel, please test it and see if it works for you. If not, it's probably hub-specific and giving us information about your particular hub may help.
Urk. Just moved everything to a laptop running RC1, and everything works fine (except that no modules are loaded as a result of discovering devices in USB-land). The other machine (TYAN Tiger 100 MoBo) must have some bogus CMOS settings.... Will abuse that machine later....
