http://bugzilla.opensuse.org/show_bug.cgi?id=898395 --- Comment #15 from Bit Juggler <suse.junky@t-online.de> --- As promised i did some more testing with my desktop (Motherboard: MSI MS-7918/Z97 GAMING 3 (MS-7918), BIOS V2.3 07/24/2014). In all tests i started the machine, logged in as root, plugged the device into an USB port, saved the dmesg result and then restarted the machine. I did this for every USB2.0 and for every USB3.0 port available. The first device tested was the USB2.0 bluetooth adapter (0400:080a). Plugging it into any of the USB2.0 ports resulted in a message like this: [ 34.960224] usb 3-8: new full-speed USB device number 4 using xhci_hcd [ 35.113171] usb 3-8: device descriptor read/64, error -71 [ 35.214125] xhci_hcd 0000:00:14.0: Setup ERROR: setup context command for slot 3.

Plugging it into any of the USB2.0 ports resulted in a message like this: [ 44.594128] usb 3-8: new high-speed USB device number 4 using xhci_hcd [ 44.759627] usb 3-8: New USB device found, idVendor=04a9, idProduct=1907 [ 44.759634] usb 3-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 44.759638] usb 3-8: Product: CanoScan [ 44.759642] usb 3-8: Manufacturer: Canon Plugging it into any of the USB3.0 ports resulted in a message like this: [ 178.405949] usb 3-11: new high-speed USB device number 4 using xhci_hcd [ 178.571387] usb 3-11: New USB device found, idVendor=04a9, idProduct=1907 [ 178.571395] usb 3-11: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 178.571400] usb 3-11: Product: CanoScan [ 178.571403] usb 3-11: Manufacturer: Canon The third device tested was an USB2.0 Netgear wireless adapter WG111v2 (0846:6a00) which is currently not used with the desktop, but works with openSUSE 13.2 on this machine. Plugging it into any of the USB2.0 ports resulted in a message like this: [ 56.063756] usb 3-8: new high-speed USB device number 4 using xhci_hcd [ 56.232714] usb 3-8: New USB device found, idVendor=0846, idProduct=6a00 [ 56.232722] usb 3-8: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 56.232727] usb 3-8: Product: NETGEAR WG111v2 [ 56.232731] usb 3-8: Manufacturer: NETGEAR WG111v2 [ 56.232734] usb 3-8: SerialNumber: 00184639AF36 [ 56.361766] ieee80211 phy1: Selected rate control algorithm 'minstrel_ht' [ 56.361969] ieee80211 phy1: hwaddr xx:xx:xx:xx:xx:xx, RTL8187vB (default) V1 + rtl8225z2, rfkill mask 2 [ 56.369903] rtl8187: Customer ID is 0xFF [ 56.370256] rtl8187: wireless switch is on [ 56.370296] usbcore: registered new interface driver rtl8187 [ 58.149302] IPv6: ADDRCONF(NETDEV_UP): wlp0s20u8: link is not ready Plugging it into any of the USB3.0 ports resulted in a message like this: [ 56.468661] usb 3-11: new high-speed USB device number 4 using xhci_hcd [ 56.637653] usb 3-11: New USB device found, idVendor=0846, idProduct=6a00 [ 56.637660] usb 3-11: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 56.637664] usb 3-11: Product: NETGEAR WG111v2 [ 56.637668] usb 3-11: Manufacturer: NETGEAR WG111v2 [ 56.637671] usb 3-11: SerialNumber: 00184639AF36 [ 56.764615] ieee80211 phy1: Selected rate control algorithm 'minstrel_ht' [ 56.764761] ieee80211 phy1: hwaddr xx:xx:xx:xx:xx:xx, RTL8187vB (default) V1 + rtl8225z2, rfkill mask 2 [ 56.772725] rtl8187: Customer ID is 0xFF [ 56.773044] rtl8187: wireless switch is on [ 56.773066] usbcore: registered new interface driver rtl8187 [ 58.551182] IPv6: ADDRCONF(NETDEV_UP): wlp0s20u11: link is not ready For all USB2.0 devices xhci_hcd is used no matter whether they are plugged into an USB2.0 or an USB3.0 port. In none of the tests it made any difference whether i used the ports direct on the motherboard or the ones redirected to the front panel of my desktop. -- You are receiving this mail because: You are on the CC list for the bug.
