With the approach you're taking you're going to have no performance
whatsoever, please learn about how USB bulk transfers work, especially
about the size of URBs.
I am not. Control transfers are fine with me. There
must be a memory
region where traffic I/O takes place.
There is no such 'memory region', because the FIFO of the RTL2832 has
it's own memory, which is completely outside of the 8051 address space
and thus cannot be accessed with control transfers.
Anyway, I'm out of the discussion.
