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.
