Hi All,
I get an Error Code during Configuration set up of USB for rare USB drive.
below is the error Message Printed on uart
usb 2-1: new high speed USB device using fsl-ehci and address 28
usb 2-1: can't set config #1, error -71
usb 2-1: USB disconnect, address 28 hub 2-0:1.0: unable to enumerate USB device on port 1
This is the code
c = usb_choose_configuration(usb_dev);
if (c >= 0) {
result = usb_set_configuration(usb_dev, c);
if (result) {
dev_err(&usb_dev->dev,
"can't set config #%d, error %d\n", c, result);
/* This need not be fatal. The user can try to
* set other configurations. */
}
}
dev_info(&usb_dev->dev, "authorized to connect\n");
I want to send this error code to USER SPACE.
The Possible Implementations i thought of Is
> IOCTL
> Signal from Kernel to User Space
> dmesg read
Can anybody suggest the efficient mechanism to do this.
