Comment 438 for bug 88746

For those of you with USB 2.0 controllers still experiencing this bug, try building ehci_hcd into your initramfs, i.e., echo ehci_hcd|sudo tee -a /etc/initramfs-tools/modules && sudo update-initramfs -u .

(To note, for 9.04, the usb controller drivers may be built with =Y instead of =M, which works around an embarrassingly high number of symptoms.)
