[Bug 296710] Re: warning: ehci_hcd loaded AFTER uhci_hcd and ohci_hcd

[Miguel]

I have a problem with the ehci_hcd too. The printer, HP Photosmart C4180
only works in Linux if the USb 2.0 was disabled previously in the BIOS.
But the point is that this printer has a USB 2 port which allways works
perfectly, and even does a good  job today with other operating systems.
I believe this problem is related with the ehci_hcd  "thing", I can't
find the module in my filesystem.

Some data:
