2.6.18.2 ECHI/mass storage: irq status 0002 ERR/ hub_port

Hi,
We were assessing the performance of our USB
controller on ARM11/2.6.18.2 platform for mass storage
devices.
Currently we tested Seagate/Maxtor HDDs and
everything was running. Of late we received new USB
storage devices(Western digital, which are quite
smaller in size). The problem with these is that, they
are outright not working.
Digging back the archives tells me that the problem
could be in dma pool/cache memory. Any pointers would
help.
Thanks
Syed
