Hmm. I'm not sure that the winusb drivers will work on XP SP1. You could try changing the .inf to install libusb0 instead of winusb, and see if that works. Uninstall first, then edit spyd3.inf and change line 54 from: NTx86.5.1_Device = "WINUSBCO_DEV" ; 32 bit WinXP to NTx86.5.1_Device = "LIBUSB0_DEV" ; 32 bit WinXP and then try installing again.
