1. usb: fix wrong capacity report for USB mass storage device …

   Usb "write" method never copies the input data buffer, it uses the
   buffer pointer directly. The fact that it was on the stack made
   the buffer ephemeral, and could disappear before the USB transfer
   actually occurred. The data transmitted was then random. This commit
   converts the transfer buffer to a static buffer, so that it always
   exists for the duration of the USB transfer.
   
   Known side-effect: if "read capacity" command is read twice
   simultaneously, the same buffer will be used twice. As the capacity of a
   USB drive should not change between 2 calls, this side effect can be
   ignored.
