On the CyConsole.pdf user's guide at the very bottom there is a chapter explaining how to use CyConsole to connect to a driver with a different GUID. More precisely there is written:
CyConsole was designed with provision for connecting to other CyUSB.sys drivers that have different GUIDs. On the Misc. tab sheet you will notice a drop-down list labelled Access devices attached to this driver . The drop-down list is populated with the file names of all copies of CyUSB.sys that are installed in the system. (It gathers the list from the Windows registry.)
According to this my first question is: if I want my custom driver (with my custom VID and GUID) is it ok to copy the cyusb.sys and the cyusb.inf, change their name to mydevice.sys and mydevice.inf and modify the INF file with my VID and GUID?
Secondly, I tried this approach, then I signed my driver and I installed it (now it is located under System32\drivers\mydevice.sys) but still I do not see any other driver in the drop-down list in the Misc. tab. What am I missing? (I'm using Windows 7 64bit).
Solved! Go to Solution.

I don't file with extension .inf can be uploaded. Please change the extension to .txt and upload. That should work.

hi PRJI:
this inf file seems to be universal?meens not specific for win7 64bit? and you still have to resart with F8 to get the xxx.sys work(xxx.sys is cyusb.sys with a different name)?
Secondly, what about the bottom GUID in the inf file? changing it leads my device to be unrecognizale to the cyusb.sys, how can solve this? thank you.
B.R.,
WH

>> Applications software usually accesses the driver using the driver's Global Unique IDentifier (GUID).Each driver in the Windows system should have a unique GUID. By employing distinct GUIDs, multipleinstances of CYUSB3.SYS from different hardware vendors can exist on a given system without colliding.
I would suggest you to change "CyConst.SetClassGuid("{CDBF8987-75F1-468e-8217-97197F88F773}");" in your host application with your GUID.
Thanks

Hi,
I apologize for the above wrong post about custom GUID.
Its not classGUID, its customer GUID, but before going to the APIs please let me know which library are you using, CyAPI.lib or Cyusb.dll,?

Hi
Thank you for your reply. I'm using CYUSB.dll, wanna change the "CYUSB.GUID= "{AE18AA60-7F6A-11d4-97DD-00010229B959}" " in the inf.
