to the 2.4 tree and according to Greg, was also applied to
2.5, but as it does not appear in 2.6.0-test1 so I have combined it
with my new patch and modified the file header changelog in
ftdi_sio.c accordingly.

to the 2.4 tree. This did not have a changelog entry in
the file header comment of ftdi_sio.c, so I have retroactively
added one in the attached patch.

I'm a newbie as far as the 2.5.x kernel is concerned, but MOD_INC...
and MOD_DEC... seem to be frowned upon now, so what's the best way
around this problem? I'm guessing it happens in the Visor driver
too?

Does the same thing happen on 2.5
get transmitted and the
driver finally gets its 32 write bulk callbacks.
If I repeat the test using the normal UHCI driver (usb-uhci) this
problem does not occur. Also if I connect the FTDI serial
converter to an OHCI hub using the usb-ohci driver, the problem
does not occur.
