Graeme, Could there be any (easy?) way to automate the switch from, say, the native X-Rite i1 drivers to the Argyll?s i1 drivers on WindowsXP/Vista? I have a computer lab of 19 WinXP workstations I don?t have Administrator?s rights on and just shiver at the prospect I?ll have to beg the lab technician, once again ? these guys are so uncooperative ? to substitute the native X-Rite drivers for Argyll?s libusb.sys driver. They hate to do this because they have to go to every machine in the lab to make the change *before* the students can get to dispcal and the the rest of your utilities. I wonder if there couldn?t be some batch commands that could be issued from the shell to make the change happen without having to go into Manage> Device?

One could survive to the usage of F8, at my level of knowledge (near 0) not all day one profile his montor... but could i suggest to add this info into the readme? and gretag series of display one lt could be counted as working.

There's some workaround one could use that i've missed? It's difficult to provide a 64 bit libusb driver due to Microsoft policy of insisting that all drivers need to be signed to be installed on Vista 64. Some people have reported success by installing the "SIXAXIS libusb-win64" package, but it is unsigned too, and the only workaround is to press F8 during every boot that you want to use it. A google turns up <http://www.4shared.com/file/41034572/1c815fbc/SIXAXIS.html> but who exactly created it, I'm not quite sure. A possible workaround to needing F8 is <http://www.ngohq.com/news/13829-driver-signature-enforcement-overrider-ngoh q-com.html>, although I can't vouch for it. In the longer run I'm hoping to make use of the Microsoft supplied winusb.sys driver as a way of accessing instruments without a signed driver. Graeme Gill.
