usb 2.0 being recognized as usb 1.1

I saw that a transfer to an external usb drive was going terribly slow. As the title says, my usb ports are all 2.0 ports. the output of lsusb is follows:

Bus 002 Device 002: ID 03f0:2c24 Hewlett-Packard Logitech M-UAL-96 Mouse
Bus 003 Device 002: ID 054c:0174 Sony Corp.

what is the output of lspci -v ... specifically, what is the kernel drive in use for the usb controller?

twistedcubic · 2012-08-15 01:57:54

they're all pretty similar

00:1d.0 USB controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #1 (rev 02) (prog-if 00 [UHCI])
	Subsystem: Sony Corporation Device 8159
	Flags: bus master, medium devsel, latency 0, IRQ 16
	I/O ports at e000 [size=32]
	Kernel driver in use: uhci_hcd

I see that its uhci_hcd (when I imagine it should be ehci_hcd)

I tried to manually "modprobe ehci_hcd" but it doesn't seem to do the trick..

The first noticeably important output of dmesg, if that is helpful is

did you try modprobe -r uhci_hcd first? the system has a pretty hard time trying to apply a kernel driver to a device that already has a driver in use. maybe try blacklisting uhci_hcd and see if it udev then applies ehci_hcd upon reboot. this is not an issue I have faced, but that is where i would start.

tomegun · 2012-08-15 06:07:05

Are you on a standard kernel? /usr/lib/modprobe.d/usb-load-ehci-first.conf should try to make sure the modules are inserted in the right order.

If I try to run modprobe -r uhci_hcd, I get the following from lsusb:

 unable to initialize libusb: -99

This is both after just running that command, as well as after running that command and then following it with a modprobe ehci_hcd.

If I blacklist uhci_hcd and then reboot, lsmod gives me the same output as before. For whatever reason it still loads the uchi_hcd module:

 uhci_hcd               19808  0 
usbcore               123457  5 uas,uhci_hcd,usb_storage,usbhid
usb_common               622  1 usbcore

Yep, I'm on 3.4.8 standard kernel. That file you mention is there, here are the contents.

 softdep ohci_hcd pre: ehci_hcd
softdep uhci_hcd pre: ehci_hcd

I checked the BIOS to see if there are any options regarding power and/or USB and I don't see anything. I also tried to boot into a live cd of a different distro-- I get the same output for lsusb, still only usb 1.1. I should note that this desktop has 7 USB 2.0 ports, so it's also a bit strange why they aren't all showing up.

twistedcubic · 2012-08-16 15:43:50

I tried to reboot with lts kernel -- no success. I then tried a live cd of debian 6... which has a pre 3.0 kernel, and still no success. I'm starting to wonder if it's a hardware issue...

gilmoreja · 2012-08-16 18:01:22

Some of mine are the same way when they should all be 2.0 (besides the two 3.0s).

I hadn't experienced slow file transfers, so I never noticed this was even happening.
