USB problem after upgrade

  Hello,

  after upgrading my Thinkpad T20 notebook from 7.0-CURRENT updated
at March 4 to a recent CURRENT I've experienced a problem with USB
mouse. After plugging mouse in I got in dmesg:

usb_new_device: set address 2 failed - trying a port reset
usb_new_device: set address 2 failed
uhub_explore: usb_new_device failed, error=SET_ADDR_FAILED
uhub0: device problem (SET_ADDR_FAILED), disabling port 1

After some time I unplugged the mouse, and plugged it again. After
~ 5 second pause it has been detected:

ums0: <Genius NetScroll + Traveler, class 0/0, rev 1.10/1.10, addr 2> on uhub0
ums0: 3 buttons and Z dir.

But it works incredibly bad. Mouse cursor starts to move a couple seconds later
than the actual move of the mouse. Cursor doesn't move smoothly, but jumps.

My USB bus is now detected with the following dmesg:

uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x1860-0x187f irq 11 at device 7.2 on pci0
uhci0: [GIANT-LOCKED]
uhci0: LegSup = 0x3000
usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0
usb0: USB revision 1.0
usbd_get_string: getting lang failed, using 0
uhub0: <Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb0
uhub0: 2 ports with 2 removable, self powered

Before upgrade, with kernel built in March, the dmesg was same.
