Hi,

For quite some time now, I have to patch every kernel I use on my subnotebook to get usb 1.1 (ohci) properly working: It appears the BIOS of this machine has a bug, and does not do the HC TakeOver correctly. Without this[1] patch, ohci-hcd simply doesn't load, and I am unable to use USB 1.1 devices. Since the internal wlan card, and my external braille display are both USB 1.1, this is quite a serious issue for me.

Can you think of some way to properly fix this such that the fix
could go into mainline kernels?

A module option to disable the BIOS/SMM handshake would be appropriate ... maybe "broken_bios" would be clear enough, have the test say "if (OHCI_CTRL_IR is set AND !broken_bios)" then kick the boot firmware off that controller.
