hub usb 1.1 versus usb 2.0

[kslack]

When I plug my usb bluetooth module direct to usb port, then this worked fine. But when I plug this device to usb 2.0 hub, then this KO. Need I for usb 1.1 devices usb 1.1 hub? Sorry for my bad english.

try "rmmod ehci-hcd" when using USB2.0 hub or use USB1.1 hub alternatively.
