Hi,
As i have brief in the procedure in my previous mail, HID, USB HID modules
has to be compiled and loaded to get USB Keyboard information. All modules
(usbcore.ko, musb_hdrc.ko, hid.ko, etc) has to be installed with 'insmod'.
Any one has suggestion for my issue? I dont have any clue why im getting "usb
1-1.3: reset low speed USB device using musb_hdrc and address 4" error for USB
mouse when both USB keyboard and USB mouse are connected?
Regards,
Suyambu.

Hi
I was trying to install a USB keyboard in a DaVinci EVM but the usbcore.ko
doesn´t shows up when I use the modprobe to install it. Even a locate command
doesn´t find it. How did you compile the kernel to provide this module?
Thanks in advance

I am trying to use USB Mouse and USB Keyboard simultaneously through external
USB Hub on DVEVM board. I tried with v2.6.23-rc3-davinci1 and v2.6.21-omap1
versions of kernel and im unable to succeed working USB Mouse and USB keyboard
simultaneously with any of these two kernels.
The procedure i followed is:
1. Enabled all necessary modules as lodable modules - usbcore.ko,
musb_hdrc.ko, hid.ko, usbhid.ko and loaded after booting the kernel in proper
order.
2. Created Event Interface (evdev.ko) and loaded to capture the event.
3. I connect external USB HUB and plug in USB Mouse and USB Keyboard through
USB HUB. Then I do,
cat /dev/input/event2 - device file created for keyboard.
Getting keyboard scan keys if i press the keys in USB keyboard.
But if i do,
cat /dev/input/event0 - device file created for USB Mouse.
I get continuouly the followin message,
"usb 1-1.3: reset low speed USB device using musb_hdrc and address 4"
I traced the code and found that it is failing with EPIPE error (ENDPOINT
stalled).
4. But, if i connect only one (USB Mouse or USB Keyboard), both are working
fine. Getting scan keys for both USB mouse and USB Keyboard. Only when i
connect both, i get error for mouse, but keyboard is ok. What could be the
problem. Is there any issue in using both USB mouse and USB keyboard same time?
What to be modified to make both work???
Thanks in advance for the suggestions.

Suyambu.
