hi all,

in my driver i need to provide synchronous read/write
operations to the application. moreover, operation
cancellation is also needed. 

-what is the most recommended way to wait for
completion of an urb?
-i was planning to use a modified version of
usb_start_wait_urb() used inside usb_bulk_msg()

is any better methods possible?

rgds,
prageeth
