Another weird USB 3.0 problem. OS is "11.1-RELEASE-p4 FreeBSD 11.1-RELEASE-p4 #0: Tue Nov 14 06:05:10 UTC 2017", recent production version. Motherboard is a JetWay NF99FL, with a 32-bit Atom, which has a handful of USB 2.0 ports, and two USB 3.0 ports. The xhci driver is loaded, and the ports are recognized:
I just bought a small external Seagate USB disk. When I plug it into a USB 2.0 port it works great:
When I plug exactly the same disk into the USB 3.0 port, the little "power" indicator light on the disk turns on. But the FreeBSD doesn't see the disk at all: no dmesg lines show a new device inserted, nothing shows up in the output of usbconfig. The port itself works electrically, I can plug a keyboard or mouse into it and it functions correctly. For lack of information from debugging utilities like
Any ideas? This is not a big disaster: The disk isn't all that fast in hardware, and my workload is not very intense (it is only used for backup on its own ZFS file system, and backup runs for ~90 seconds every 2 hours on a normal-speed disk). So getting at most 40 MByte/sec is not a disaster. But it bugs me that it doesn't work.
Code:
# pciconf -lv | grep xhci
xhci0@pci0:4:0:0: class=0x0c0330 card=0x56781234 chip=0x10421b21 rev=0x00 hdr=0x00
# kldstat -v | grep xhci
