Description of problem: When a USB-2 device is plugged in, the following messages are displayed in the dmesg says : [111993.801050] usb 7-2: new high-speed USB device number 3 using ehci-pci [111998.304068] usb 3-2: new full-speed USB device number 3 using ohci_hcd [111998.442999] usb 3-2: not running at top speed; connect to a high speed hub [111998.458040] usb 3-2: New USB device found, idVendor=0930, idProduct=6545 [111998.458046] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [111998.458049] usb 3-2: Product: DataTraveler G2 [111998.458051] usb 3-2: Manufacturer: Kingston [111998.458053] usb 3-2: SerialNumber: 0013729828EEBA4045FF0223 [111998.464033] scsi9 : usb-storage 3-2:1.0 So, the USB-2 device is initialised as a USB-1.1 device that results in a low speed transmission. # hdparm -t /dev/sde /dev/sde: Timing buffered disk reads: 4 MB in 4.42 seconds = 927.10 kB/sec If found the following work around (that I don't understand) that is a little tricky on :http://www.geekdevs.com/2010/04/solved-unable-to-enumerate-usb-device-disabling-ehci_hcd/ # cd /sys/bus/pci/drivers/ehci_hcd/ # ls 0000:00:12.2@ 0000:00:13.2@ bind module@ new_id remove_id uevent unbind # echo -n "0000:00:13.2" > unbind # echo -n "0000:00:13.2" > bind Now, dmesg says : [114689.723154] usb usb7: New USB device found, idVendor=1d6b, idProduct=0002 [114689.723158] usb usb7: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [114689.723161] usb usb7: Product: EHCI Host Controller [114689.723163] usb usb7: Manufacturer: Linux 3.8.13.4-desktop-1.mga3 ehci_hcd [114689.723165] usb usb7: SerialNumber: 0000:00:13.2 [114690.025041] usb 7-2: new high-speed USB device number 2 using ehci-pci [114690.144607] usb 7-2: New USB device found, idVendor=0930, idProduct=6545 [114690.144613] usb 7-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [114690.144616] usb 7-2: Product: DataTraveler G2 [114690.144619] usb 7-2: Manufacturer: Kingston [114690.144621] usb 7-2: SerialNumber: 0013729828EEBA4045FF0223 [114690.153046] scsi10 : usb-storage 7-2:1.0 And the speed is correct : # hdparm -t /dev/sde /dev/sde: Timing buffered disk reads: 54 MB in 3.03 seconds = 17.79 MB/sec Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.

(I don't know if kernel 3.10 from the testing repo could help)

check in /etc/modprobe.conf or /etc/modprobe.d/* if there is a reference to ochi-hcd, and if it's listed before echi-hcd.
I found : $ cat /etc/modprobe.d/01_mga-config.conf install scsi_hostadapter /sbin/modprobe pata_atiixp; /bin/true install usb-interface /sbin/modprobe ohci_hcd; /sbin/modprobe ehci_hcd; /sbin/modprobe ehci_pci; /bin/true alias sound-slot-0 snd_hda_intel alias sound-slot-1 snd_hda_intel and : $ cat /etc/modprobe.conf install scsi_hostadapter /sbin/modprobe pata_atiixp; /bin/true install usb-interface /sbin/modprobe ohci_hcd; /sbin/modprobe ehci_hcd; /sbin/modprobe ehci_pci; /bin/true alias sound-slot-0 snd_hda_intel alias sound-slot-1 snd_hda_intel This is strange. I have another computer under mga-3 (where USB-2 works fine) where ohci_hcd does not appear in /etc/modprobe.conf and /etc/modprobe.d/01_mga-config.conf : # cat /etc/modprobe.conf install scsi_hostadapter /sbin/modprobe pata_via; /bin/true install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe ehci_pci; /sbin/modprobe uhci_hcd; /bin/true I'd like to know who configure these 2 files becauses they are 2 fresh install (one from x86_64 DVD, the other from i586). As the 1st computer is a remote one and I have no-one to make the test this week-end, I'll try to remove ohci_hcd from modprobe and check the result next week.
After removing /sbin/modprobe ohci_hcd from /etc/modprobe.conf : # cat /etc/modprobe.conf install scsi_hostadapter /sbin/modprobe pata_atiixp; /bin/true install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe ehci_pci; /bin/true alias sound-slot-0 snd_hda_intel alias sound-slot-1 snd_hda_intel and rebooting, I get : # dmesg [ 109.661050] usb 7-1: new high-speed USB device number 3 using ehci-pci [ 109.781840] usb 7-1: New USB device found, idVendor=0930, idProduct=6545 [ 109.781848] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 109.781852] usb 7-1: Product: DataTraveler G2 [ 109.781855] usb 7-1: Manufacturer: Kingston [ 109.781857] usb 7-1: SerialNumber: 0013729828EEBA4045FF0223 [ 109.794254] scsi9 : usb-storage 7-1:1.0 [ 110.831731] scsi 9:0:0:0: Direct-Access Kingston DataTraveler G2 PMAP PQ: 0 ANSI: 0 CCS [ 111.845328] sd 9:0:0:0: [sdd] 7827456 512-byte logical blocks: (4.00 GB/3.73 GiB) # hdparm -t /dev/sdd /dev/sdd: Timing buffered disk reads: 50 MB in 3.02 seconds = 16.54 MB/sec But it seems that ohci_hcd is still loaded automatically : # lsmod|grep ohci_hcd ohci_hcd 37653 0 usbcore 218676 5 usb_storage,ohci_hcd,ehci_hcd,ehci_pci,usbhid and is required by the mouse. "rmmod ohci_hcd" makes the remote mouse unusable.
In fact, it works sometimes only. Connecting a harddisk on another device (a TV) and then reconnecting it on the computer sets it at low speed. dmesg : [261663.561074] usb 7-1: new high-speed USB device number 8 using ehci-pci [261668.632116] hub 7-0:1.0: unable to enumerate USB device on port 1 [261668.922083] usb 3-1: new full-speed USB device number 4 using ohci_hcd [261669.064109] usb 3-1: Parent hub missing LPM exit latency info.

I can't test with kernel 3.10 because it requires too much change in the present configuration (kernel-firmware*)
