Have you spoken to the hardware people at Intel about this? They should be interested in hearing about failures in their host controllers. > What do you think about > dynamically adding device VID:PIDs to a blacklist? How safe would it be to populate this list? That is, how sure can you be that once a device fails with LPM enabled, you can get it to work again simply by turning off LPM? Also, how annoying will it be for users if their device fails and has to be reset (or replugged) every time they boot?
