I have no logitech devices, and no problem with middle click doing  
paste in most circumstances, but open link in new tab in browsers with  
5.5.0.

Do you really need to start from scratch, or just go through every page  
and item starting with your current .config?

No direct advice here, but when I run xconfig and search on Logitech, I  
get four entries.  In case the "Depends on" might point you to what  
higher level item you need to turn on, here are the help screens from  
each.  The Location entry should hopefully give a hint where to look  
for them.   In my case, since the first is set to no, the other three  
only show up under search, but not in the main window.

Logitech devices (HID_LOGITECH)

CONFIG_HID_LOGITECH:

Support for Logitech devices that are not fully compliant with HID  
standard.

Symbol: HID_LOGITECH [=n]
Type : tristate
Prompt: Logitech devices
Location:
-> Device Drivers
-> HID support
-> HID bus support (HID [=y])
-> Special HID drivers

Depends on: INPUT [=y] && HID [=y] && LEDS_CLASS [=y]
-------------------
Logitech Unifying receivers full support (HID_LOGITECH_DJ)

CONFIG_HID_LOGITECH_DJ:

Say Y if you want support for Logitech Unifying receivers and devices.
Unifying receivers are capable of pairing up to 6 Logitech compliant
devices to the same receiver. Without this driver it will be handled by
generic USB_HID driver and all incoming events will be multiplexed
into a single mouse and a single keyboard device.

Logitech HID++ devices support (HID_LOGITECH_HIDPP)

CONFIG_HID_LOGITECH_HIDPP:

Support for Logitech devices relyingon the HID++ Logitech specification

Say Y if you want support for Logitech devices relying on the HID++
specification. Such devices are the various Logitech Touchpads (T650,
T651, TK820), some mice (Zone Touch mouse), or even keyboards (Solar
Keyboard).

Symbol: HID_LOGITECH_HIDPP [=n]

HIDRAW [=y] && HID_LOGITECH [=n]

Logitech force feedback support (LOGITECH_FF)

CONFIG_LOGITECH_FF:

Say Y here if you have one of these devices:
- Logitech WingMan Cordless RumblePad
- Logitech WingMan Cordless RumblePad 2
- Logitech WingMan Force 3D

and if you want to enable force feedback for them.
Note: if you say N here, this device will still be supported, but  
without
force feedback.

Symbol: LOGITECH_FF [=n]
