Attached to the port is a

uhub1: NEC Corporation USB2.0 Hub Controller, class 9/0, rev 2.00/1.00, addr 2
uhub1: 4 ports with 4 removable, self powered

on this hub is a 

ums0: Logitech USB Receiver, rev 1.10/9.10, addr 3, iclass 3/1
ums0: 5 buttons and Z dir.

This is from the dmesg of my desktop system (USB 1.1 only).

If I attach this combo to the other system ehci tells me:
---snip---
usb4: unrevoerable error, controller halted
usb4: blocking intrs 0x10
---snip--
and stopps booting further.

The usb part of the dmesg without anything attached:
