Hi Thanks for the suggestion; I tried them all (enabling one at a time, but ending up with all four set), and I get the same USB_ERR_TIMEOUT loop on each boot. Note that even before I get to the FreeBSD bootloader screen (so while the UEFI thing is initialising), there's a very significant (5-10s) delay on a warm boot, during which the keyboard caps lock light won't toggle; this doesn't happen on a cold boot. For this reason, I strongly suspect a hardware failure. My main question is really, how I figure out if it's the CPU or the motherboard at fault. I'd rather not change the wrong one, or unnecessarily change a working part. I notice the internet has quite a few stories of this motherboard having USB difficulties (allegedly due to build quality issues); that would be my main suspicion, although I managed to bend some of the CPU pins, and had to bend them back with a needle, so I can't rule that out either (note: I did get all the pins back straight, and none fell off, or gave a feeling of wobbliness or weakness).
