Vinturis,
Did you check the “drivers” shell cmd output? Did you see how many children
managed by UsbBus driver?
Did you check “dh” cmd output on corresponding handle?
Please attach the log of these cmds to me. we can help narrow down what
happened here.
Thanks
Feng

Hi Brian,
I'm not working with the UEFI Driver Wizard, I just started from the
FtdiUsbSerialDxe driver [Justin Phipps]. More information about this is here:
http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=Tasks/USB_Serial_Adapter_driver
.
This driver am loading manually from the UEFI Shell, and when I am enumerating
the USB devices I cannot see the FTDI FT4232 device.
Thanks,
Sorin

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
