Control center has this option of converting USB requests sent to script file.
Recording the firmware download and storing it as a .spt file is the way to convert it. The current control center and cyusb3.sys driver does not support it. We'll be adding this support by late next month. Will update here once it is done.
Any update on this?
Yep, this support has been added. Can you use SDK 1.1 and give this a try.
