Razor hardware only works on USB 3 ports (re-opened)

Hi, I have a Razor Deathadder 1500dpi mouse and the Razor Deathstalker keyboard. Both work perfectly fine on my laptop when I boot into Windows 7 but if I boot into Gentoo GNU/Linux neither seem to work unless I plug them into my USB 3 port which is weird. Since I only have one USB 3 port and I don't have a USB hub I cannot use both at the same time in Linux. Is anyone else having this issue? Any possible solution to this problem?

Are the mouse and keyboard USB 2 devices? If so, do you by any chance have CONFIG_USB_EHCI_HCD=n (USB 2 support disabled) in your kernel configuration?

They are USB2 devices, both were released before USB3 was finalized and both work in Windows on the USB2 ports.

In my kernel .config I have

Do you also have CONFIG_USB_OHCI_HCD=y and CONFIG_USB_UHCI_HCD=y? If not, might be worth trying those too to see if they change anything. If other USB 2 devices work when plugged into the USB 2 ports, I wonder if the problem is due to the Razer drivers?

<3,

In your Gentoo, connect both devices to USB 2.
Boot the system.

Post the output of lsusb
Put dmesg onto a pastetbin
Put your kernel config onto a pastebin.

I have a dim memory that Razor Deathadder/Deathstalker equipment is not properly USB HID compliant and needs a Special HID drivers kernel option.
I don't recall which one but the above info should help narrow it down, if my memory is correct.

NeddySeagoon,

Looks like you're on to something there. I've just noticed the following in the Gentoo Wiki:

Fitzcarraldo,

That allows USB2 hardware that supports transaction translation to support USB1 speed devices directly.
USB 3 will drive USB 1 devices without any extra options.

Well spotted.

It depends on the USB 2 root hubs, rather than the USB 1 devices that are connected.

I'm not sure which one of those kernel options did it as I enabled them all at the same time, recompiled then rebooted. Now the mouse & keyboard work. SOLVED!

Not sure if this is related but I am still having problems with my input devices. Sometimes when I reboot my kb/mouse don't world sometimes they do, I usually have to reboot a few times before they work.
