Just a few updates:

A fellow OSer at osdev.org posted a concern with Bochs and the UHCI code. Come to find out, it was a small bug in the interrupt code due to deferred packets. I have made a fix and hopefully it will be posted to Bochs soon.

I am still doing work on the new USB Attached SCSI (USB UAS) protocol, and progress should be done soon.

Thank you, Ben

Unfortunetly, I haven't had much time to work on any of my projects. My real jobs have been taking most of my time.

I have done a little work on Volume 3 with ATAPI devices, updated some documentation and code for the next edition.

I am still trying to decide what to base Volume 5 on. If you have any ideas, please let me know.

I have been doing a little work on the new USB Attached SCSI (USB UAS) protocol, though a bit more work is needed.

One thing I would much appreciate from my readers is if you find comments or reviews, good or bad, on other sites, please send me a note on where you found it. I would love to read them.

Thank you, Ben
