    Relevant part is:

    Controller /dev/usb3:
    addr 1: full speed, self powered, config 1, UHCI root hub(0x0000),
    VIA(0x0000), rev 1.00
     port 1 powered
     port 2 addr 2: low speed, power 50 mA, config 1, product
    0x006a(0x006a), vendor 0x045e(0x045e), rev 0.17

    I also dug up another mouse (a micro innovations wireless unit):

    Controller /dev/usb3:
    addr 1: full speed, self powered, config 1, UHCI root hub(0x0000),
    VIA(0x0000), rev 1.00
     port 1 powered
     port 2 addr 2: low speed, power 100 mA, config 1, Wireless RF
    Mouse(0x0101), Cellink Co., LTD.(0x1733), rev 0.01

    with similar results.

    Then tried a different USB port (even though it works perfectly fine
    with both Windows and Ubuntu).

    Again, detected fine:

    ums0: Cellink Co., LTD. Wireless RF Mouse, rev 1.10/0.01, addr 2, iclass 3/1
    ums0: 3 buttons and Z dir.

    but nothing happens with moused.

    All of the above was with ehci removed.

    Given that it now appears to be stalling with two different mice, from
    two different vendors, it would appear to be something at fault with the
    handling of the USB chipset. Again, for reference:

    usb0: <VIA 83C572 USB controller> on uhci0
    usb0: USB revision 1.0
    usbd_get_string: getting lang failed, using 0
    uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
    uhub0: 2 ports with 2 removable, self powered

    This is on an MSI K8T Neo-FSR mainboard with a Socket 754 Athlon 64
    running -CURRENT as of today (6/28/2005).

    Both mice work fine when connected via a USB->PS/2 converter.
