Hi, I have some hardware with a USB3 controller that is detected by xhci(4), but when I try attach a USB3 device, it fails to attach to a USB3 bus, and after timing out it connects to a USB2 bus. Here's a verbose dmesg with xhci debugging enabled from when I plug the device in: http://pastebin.com/nM8nQFg3 I've captured xhci(4)'s verbose boot time dmesg output here: http://pastebin.com/EA3k7RLE The full verbose boot dmesg is at: http://pastebin.com/Y0qKiDZg And a regular boot dmesg is at: http://pastebin.com/e3tS8eS4 I've tried tweaking a handful of BIOS options like XHCI handoff and USB transfer timeout thresholds, but nothing seems to help. Have already upgraded to the latest BIOS available too. This FreeBSD 9.0-STABLE build is about 1 week old. Any help greatly appreciated! Thanks, Aragon
