Seen that sort of thing too. In my case, another XP box that had got stuck trying to do one particular update (I forget what it was for.) Long story short, after trying all the usual stuff, I eventualy booted a Memtest86 CD. After a long time (not the quickest PC, and it had at that time 384Meg of RAM, not much even for XP) it failed on one sticky bit, right at the top of memory, but only with the very last (most complex) test!... I isolated which memory stick was the issue by removing one and retesting, then swapping and testing again. On talking with the owner, they accepted my suggestion to max out the RAM anyway as it would be cheaper at that time, than trying to replace a single 256Meg stick. 1G of new ram later, it ran like a new machine! (And the suspect update applied itself with no error.) In your USB keyboard case, I'm not saying that memory issues will be the cause, just agreeing that it could be a posible cause. (I didn't know however, that the 64 bit versions of FBSD install disks, startup in 32 bit mode, that needs documenting somewhere, or on screen as you begin the process.) Memtest86 will boot and run on just about anything with an Intel or AMD CPU, 32 or 64 bit. Well worth having a copy in your toolkit. http://www.memtest.org/ It can often be found on some Linux distro install CD's too, as an option to test the system before kicking off the main install, or booting to a live version of the OS. The only downside, on a large ram system, even with a slick CPU, it can still take "An age" to complete. That's the nature of real diagnositcs though. No affiliation, just another happy user.
