Hi everybody,
I t seem don't work when using Cypress sample driver. Kernel version is
2.4.17 and compiler is arm-linux-gcc 2.95.3.
According our hardware design, I have correctly modified the base_addr,
data_reg_addr and irq in hc_sl811.c.
The following is my procedure to insert USB related modules.
////////////////////////////////////////////
insmod /dll/usbcore.o
mount -t usbdevfs usbdevfs /proc/bus/usb
insmod /dll/sl811.o
insmod /dll/input.o
insmod /dll/hid.o
insmod /dll/mousedev.o
//////////////////////////////////////
And then messages show on the console
///////////////////////////////////

Then it didn't issue any interrupt when moves mouse or click buttons. So i
think it should not be drive correctly.
What is I lost ? What is I doning wrong?
Any suggestions are welcome.
Regards,
Brian
