Re: [Ftdi-usb-sio-devel] usb-uirt problems with ftdi_sio in 2.6.22.1

So I again did what I specified in the bug report

http://bugzilla.kernel.org/show_bug.cgi?id=8564
Used the ftdi_sio.h and ftdi_sio.c from
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.20.y.git;a=tree;f=drivers/usb/serial;h=535edb4ac2d4c6b03bd3ca641c44aae8013b4dd9;hb=fcfbb42bd476ed54b598d917d3b9b63d8835093e



With kernel
 uname -a
Linux home 2.6.22.1-41.fc7 #1 SMP Fri Jul 27 18:10:34 EDT 2007 i686
i686 i386 GNU/Linux

And it works with 2.6.22.1-41.  Apparently sometime after that kernel
the driver has been broken for usb-uirt, pretty much ever since.
