Initio Corporation INIC-1618L SATA chip too slow (seem to use usb1 not usb2)

[nb]

Hi,

My external disk uses a Initio Corporation INIC-1618L SATA chip.
vendor/product are : 0x13fd/0x0840 and bcdDevice is 1.14 making the disk work very slowly 12Mb in spite of 10 times faster. bcdUSB seem to be ok : 2.00
Tried this on 3.13 and 3.14-rc6

Is there a module to load specifically. In my case usb-storage is loaded.

Not really sure it's the right place to post this.
