USB HOST STACK Problem in finding class Driver.

[sandeep gulati]

Hi all

i bought 64 GB mass storage card from one company.

the card no: is IC-SSD-PMCa it detects as a 4 usb devices of 16 GB
each.

i am porting the USB Host Stack. so in class driver layers there are
lot of class drivers

i know that my class driver will be in mass storage class driver.
but there are two mass storage class drivers

1. BULK only mass storage ...

2. CBI mass storage class driver ...

so i am confused in between these two.....so please tell me which one
is for my use....

thanks in advance
