USB2 and umass devices

I have one of these PCI cards ->
ehci0: <NEC uPD 720100 USB 2.0 controller> mem 0xe9029000-0xe90290ff irq 5 at device 8.2 on pci0
ehci_pci_attach: companion usb2
ehci_pci_attach: companion usb3
usb4: EHCI version 0.95
usb4: companion controllers, 3 ports each: usb2 usb3
usb4: <NEC uPD 720100 USB 2.0 controller> on ehci0
usb4: USB revision 2.0
uhub4: NEC EHCI root hub, class 9/0, rev 2.00/1.00, addr 1
uhub4: 5 ports with 5 removable, self powered

The card is pretty generic and the NEC chip mentioned is the only major thing
on the card.

I am trying to use this device ->
umass0: Acer Labs USB 2.0 Storage Device, rev 2.00/1.03, addr 3
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <USB 2.0 Storage Device 0100> Fixed Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 114473MB (234441648 512 byte sectors: 255H 63S/T 14593C)

This is when it is connected to the internal VIA controller ->
uhci0: <VIA 83C572 USB controller> port 0xc400-0xc41f irq 9 at device 7.2 on pci0
usb0: <VIA 83C572 USB controller> on uhci0
usb0: USB revision 1.0
uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered

Unfortunately when I try and plug it into the USB 2.0 controller, I get this ->
uhub4: device problem, disabling port 1
uhub4: device problem, disabling port 2
uhub4: device problem, disabling port 3
uhub4: device problem, disabling port 4

(I tried all 4 ports)

It is running -current from the 11th.
The drive works when it's detected but it is _very_ slow (like 800kb/sec or
so). If I use the firewire port it goes faster (eg >20mb/sec).

A USB mouse works fine, so does a compact flash card reader (I can't tell
if it is doing high speed though as CF is pretty slow)

Anyone got any hints/tips/patches?
