Sorin:
I can try to help, but first a few basic questions …
1. How are you trying to test the driver? Is this being loaded from the
UEFI Shell?
2. What did you use as the starting template for a driver? Are you
working with the UEFI Driver Wizard?
Thanks ... br

Subject: [edk2] Enumeration process under UEFI for FTDI 4232 device
Hi all,
I am developing an UEFI application and I try to create a UEFI driver for FTDI
FT4232 device.
I expect that during USB enumeration process executed by the generic UEFI USB
bus driver, the UEFI USB bus driver to create a handle for the FTDI FT4232
device and to install onto that handle the EFI_USB_IO_PROTOCOL. Using the
EFI_USB_IO_PROTOCOL I want to read the “Vendor Id” and “Product ID” in order to
identify the FTDI FT4232 device.
My problem is that I can find in my system only two handles with
EFI_USB_IO_PROTOCOL (one handle for mouse, one handle for keyboard) and I can
find no handle for FTDI FT4232.
Question 1: Are you aware if there is any problem with the enumeration of the
for FTDI FT4232 device by the generic UEFI USB bus driver?
Question 2: If there is a problem with the enumeration, is there any way to fix
this issue?
Thank you very much for your answer,
Sorin
