Default Xilinx USB Platform Cable not working anymore (linux)

(Google didn't allow me to reply to the original thread, so I copied
the previous message in myself)

I've got the same problem here: the USB cable works fine with windows,
but using linux, the CPLD version is mis-read, and the only thing
happening is the firmware being updated. (which takes almost an hour,
hilarious!). I'm using ISE 8 instead of 6, but the symptoms are the
same.

I just contacted Gilles in private to see if he found any solution to
this issue yet. His workaround is the same as mine: use a windows
machine for programming with the USB platform cable. I'm sure that's
not what xilinx had in mind, when the published the Linux drivers for
this cable.

Does anybody have this cable working yet, running a 2.6 linux kernel ?

I'm not sure if I have answered in this thread or not, but my experience is
that the cable works in Linux if I have started impact in windows first. If
I don't, impact in Linux wants to upgrade the CPLD version.

I'm using ISE 8 in both Linux and Windows.

Ah, I must say I haven't tried that yet. It's terrible workaround for a
serious flaw, but if it works, it's better then nothing.

Thank you very much,
