I'm getting the following errors with my latest gregkh-2.6 kernel tree. The current 2.6.9-rc3 doesn't have these errors, and I don't see them on my ohci/ehci based laptop, only on a uhci/ehci based desktop.
I get them when I plug a usb trackball into the port after booting. Any ideas? thanks, greg k-h ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001403 POWER sig=k CSC CONNECT hub 1-0:1.0: port 1, status 0501, change 0001, 480 Mb/s hub 1-0:1.0: debounce: port 1: total
