Comment 13 for bug 275351

I have done some correspondence with Intel and it seems that the official response is that DG45ID is not (at least currently) supported on Linux and Intel is not going to fix this issue. The fact that this board works against the EHCI specification published by Intel (http://www.intel.com/technology/usb/ehcispec.htm page 121 and page 122) does not matter and all I was able to extract from Intel about this issue was "The link you provided does not relate specifically to this board and it is just general information for EHCI Controller." The fact that linux kernel tries very hard to follow that specification did not matter.

So the end result is that either you compile your own kernel with smaller timeout or try to get workaround for this issue in linux kernel some other way. Do not expect Intel to help in any way. The other response I got was "We cannot provide further information on the BIOS other than the information that is publicly available." I think this means that Intel is not going to say how the EHCI hand-off is even supposed to work!
