Re: [Libusb-win32-devel] libusb on 64 bit machines ?

I don't think Ramesh can use an .inf file install if he wants to use 
Isochronous transfers.  My understanding is that Isochronous transfers are 
not supported in libusb 0.1.

I have never used the filter driver on 64bit systems so I don't know
whether it works (or will work) or not. One piece of advice though:
save yourself the hassle of trying to get it working and use the
standard (.inf file) install.
