Nope. CyAPI uses DriverGUID to get handle and talk to CyUSB.sys. so even if CyUSB.sys is renamed CyAPI would still be able to talk to it.
Ok, thank you! Next question: the DID is 8613 for the FX2LP.. and for the examples it is 1004. I can't find anything, anywhere, in the firmware nor on the host side that defines that. The examples often just refer to some variable's address (bulkloop/fw.c) that got filled in seemingly out of nowhere? Where/What causes the device to become DID 1004 when I download bulkloop.hex ?
Thank you for your help!
doh.. nevermind. found it in the dscr.a51 files. My searches didn't find it because it's stored in little endian assembly.. 0410
