Subject: DM 6446 - MontaVista Linux 4.0.0 with USB key board has some
problem. Any Idea?
Hello All,
I am using DM6446 with MontaVista kernel, that come when we purchase the
DM6446 EVM board. I am enabled USB key board and HID driver in the kernel.
When I press capslock or NumLock key, the key board looses control. Means to
say, I can not press any more key and I can not see the key pressed on the
terminal. Any one has the idea why this happens? Do I need to upgrade the
drivers?
With best regards,
Venkatachala Upadhya|Extn: 65395|

The module parameters for speed and duplex were not being honoured
due to a coding bug resulting into auto negotiation all the time.
