Or am I all mixed up? > The problem appears to be a bug in the UHCI driver. Could be, and I certainly don't know much about this code. But it seems like the driver is being given reason to assume it has a working device when it doesn't really have one. I assume the device is unusable without its interrupt, so shouldn't it fail at probe or attach time? John -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
