Hi All,
I am emulating the USB mouse from a PPC based controller. ie PPC
acts as a mouse. Currently, I am going through usbmouse.c. Is it
enough to go through this file alone to send the X, Y co-ordinatinates
to the host PC ?
Or
put it in a simpler way, how to send the mouse co-ordinates

I use MPC 8270 based board and it has an USB 1.1

click events.

Hi All,
I am new to USB world. I have a basic doubt. I wrote the USB
driver by going through some tutorials. I compiled it and inmod it
without any problems. Now, If I want to use my driver, I need a major
number. There I got stuck up. I didnt have any major number used in
my driver. So,
open it will check minor number and open the device file.
One more suggestion is go thru USB code in Linux.
I hope you understand this.

I have a strange behavior here with my ISP 1561 PCI-USB card.

2) When I try to use the EHCI driver for this board, the device is not
accepting the address. It says the

I use control transfer to read some bytes of data from a device.
But I dont know how much data it is going to give me.
If I give less number of bytes as size, the usb_control_msg() function

I had a code that receives interrupt data from the device. It
worked with 2.4 kernel. I migrated to 2.6 kernel and it now calls the

On 2.4, I had the following and it was working. I got my
USBH__vIRQHandler() function called for every 200 milliseconds.
Thank you David and Alan for clarifying it.
