Subject: 3.18 regression: Error while assigning device slot ID, USB3 devices not detected
Date: Sun, 18 Jan 2015 00:08:18 -0600 [thread overview]
Message-ID: <54BB4DD2.1070602@gmail.com> (raw)
I've got an Intel Haswell-based system with a Gigabyte Z87X-D3H
motherboard under Fedora 21. After updating to the 3.18.2-200 Fedora
kernel, I noticed some errors in dmesg and at least some of my USB3
ports don't recognize any USB3 devices plugged into them:
[ 0.560838] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[ 0.560912] xhci_hcd 0000:00:14.0: Max number of devices this xHCI
host supports is 32.
[ 0.560990] usb usb2-port2: couldn't allocate usb_device
[ 0.561098] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[ 0.561163] xhci_hcd 0000:00:14.0: Max number of devices this xHCI
host supports is 32.
[ 0.561239] usb usb2-port5: couldn't allocate usb_device
[ 0.561344] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[ 0.561409] xhci_hcd 0000:00:14.0: Max number of devices this xHCI
host supports is 32.
[ 0.561484] usb usb2-port6: couldn't allocate usb_device
This worked fine under 3.17. Is this a known problem?
