[Libusb-win32-devel] it is possible use the libusb with an HID keyboard while the HID is under windows driver?

[Diego . <di...@gm...>]

Hello,

I have programed an HID keyboard, but I need to send some configuration
bytes and the firmware that will be save into a eeprom. I'm thinking to
include one bulk endpoint into descriptors. But, how to communicate with my
"custom HID device" using the libusb? When I plug my device windows uses hi=
s
HID driver. Could I use libusb to perform a bulk transfer when my HID devic=
e
is under windows driver?


Thank,

Sending data to a HID keyboard is possible with the Windows HID driver 
if you use feature reports.
Why do you want to change the firmware of a keyboard?

Have a look at http://www.codemercs.com for a nice range of USB keyboard 
controllers.
