I've just bought a new four-port USB hub, but it's not recognized. I've emailed the OEM, but considering that it's Linux, I'm not holding my breath. The appropriate part of dmesg follows:
usb 2-2: new full speed USB device using uhci_hcd and address 11
usb 2-2: device descriptor read/64, error -71
usb 2-2: device descriptor read/64, error -71

usb 2-2: new full speed USB device using uhci_hcd and address 14
usb 2-2: device not accepting address 14, error -71
hub 2-0:1.0: unable to enumerate USB device on port 2
FWIW, a thumb drive plugged directly into that port works, and the light on the hub comes on when it's connected.
