Hi,
We have a Cypress based usb keyboard software that enumerates as a
USB Keyboard and works properly in Windows 32 / 64 bit platforms.
When it is connected to Linux, the device enumerates as a keyboard
with proper configurations. But whatever keystrokes we send to the
host are lost. I have attached the dmesg and some more information in
the attached log. Do you have any suggestions for it ?
Thanks,
Jayaprakash.
