Hi,
The endpoint descriptor has a bit field that indicates whether the
device attached is a "low speed" or "full speed" device. Now does the
host controller interpret this field in any or is it ignored. I check
the OHCI spec and it does not specify what a controller may use this
information for. Any idea how this is used.
The problem is like this: i'm using the USB stack on a MIPS based set
top box to currently support cordless USB keyboard and mouse devices. I
find that one port (port #2) always reports the device to be a full
speed device (irrespective of the device i attach to the port). I'm
using a USS312 controller. Has anybosy seen this same problem too ??,
please clarify.
Port 1 works properly and i'm able to use it for either the mouse or the
keyboard. I'm using kernel version 2.4.2. I've ported the HC driver for
MIPS and am seeing this strange behavior when i use port 2.
I even hard coded the "slow" field in the usb_device structure to "1"
indicating a "low speed" device and i'm able to use both ports with no
problems.
Thanks for any help.
Govindan
