Depends how many of the configurations you want to be testing. Taking away all power -- including laptop batteries! -- is a different scenario than the ones which let the USB controllers supply enough VBUS current to maintain the USB suspend state. Probably simplest to get what you've been doing so far to behave before getting the others to work. It'd be interesting to toggle the BIOS support for USB keyboards+mice though. - Dave ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
