Dear Sir,
Dear Sir,
Environment: Suse 9.1 professional
Kernel: 2.6.4-52
Project: writing a USB driver for CMOS sensor
problem description:
1. the code is modified from ov511 sample source code.
2. the driver has been registered successfully.
3. videodev module also has been installed successfully.
4. the devices and drivers is located in /sys/bus/usb/devices and
/sys/bus/usb/drivers
instead of /proc/bus/usb.
5. when I execute the following code in probe() function,
value=0x02;//declare as unsigned char
actualLen=1;
rc= usb_bulk_msg(wis->dev,
usb_sndbulkpipe(wis->dev,0),
&value,1,&actualLen,HZ);
printk(KERN_ALERT "########## reg_r[1], rc=%d: %s
\n",rc,symbolic(urb_errlist,rc));
rc= usb_bulk_msg(wis->dev,
usb_recbulkpipe(wis->dev,0),
&rValue,1,&actualLen,HZ);
printk(KERN_ALERT "########## reg_r[2], actualLen=%d, buf=0x%x,
rc=%d: %s \n",actualLen,rValue,rc,symbolic(urb_errlist,rc));
printk(KERN_ALERT "########## reg_r[3] ! \n");
6. I got the error messages from /var/log/messages and shown it
as attached file.
Does anybody be able to help me to solve this problem ?
Thanks and Regards,
Jerry
