Using _CID may help some systems, but it may not be helpful for many systems having keyboard probe problem. I think it's a specification bug made by Microsoft, same devices connected different type devices should not have different ID but same ID. > > http://download.microsoft.com/download/5/7/7/577a5684-8a83-43ae-9272-ff260a9c20e2/pnp_legacy.doc > > Note that 030B is listed as reserved in this table, and not a valid keyboard > device. Yes, it's a invalid type, but reserved as a keyborad. I don't know why the BIOS builder puts PNP030B as a keyboard, but it seems to be not a bug. People with this problem can override AML code, but I don't think it is a bad idea adding other IDs to the list for probing. -- kaho@elam.kais.kyoto-u.ac.jp
