dCBWDataTransferLength is the number of bytes to be transferred in the
data stage. The "Transfer Length" fie
Could someone tell me the difference between "dCBWDataTransferLength" field
of CBW and "Transfer Length" field of CBWCB (e.g. READ(10) )?
Another question is; Do we need to have DMA capable memory allocated for
reading data from a USB mass storage device?

I hate to say this, but it sounds like you're in _way_ over your head
But, here are a few pointers:
First, read the documentation on usb.org -- specifically, read the section
on class-specific drivers. What you'll find is that the Cls=08 means that
it conforms to the USB Mass Storage specific
I have a USB 8IN1 card reader and when I insert the device, I get following
new entry in /proc/bus/usb/devices
T: Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=058f ProdID=9360 Rev= 1.00
S: Manufacturer=Generic
