Dear Greg and Alan,

Well, OK, but I will change it as follows:

result = usb_stor_control_msg(us, us->send_ctrl_pipe,
USB_REQ_SET_FEATURE,
USB_TYPE_STANDARD | USB_RECIP_DEVICE,
0x01, 0x0, NULL, 0x0, 1000);

Because the parameters of USB_REQ_SET_FEATURE, USB_TYPE_STANDARD and USB_RECIP_DEVICE are all Hex, so I want to keep my other parameters to be consistant with them.
And I see the same using with me in the kernel. Such as the code of the function usb_stor_euscsi_init in initializers.c file.

Is this changing can be accepted by you?

If so, I will resubmit the new patch as soon as possible.

Hope for your reply soon.

Thanks.

The original codes are:
us->iobuf[0] = 0x1;
result = usb_stor_control_msg(us, us->send_ctrl_pipe,
USB_REQ_SET_FEATURE,
USB_TYPE_STANDARD | USB_RECIP_DEVICE,
0x01, 0x0, us->iobuf, 0x1, 1000);

Best Regards,

Franko Fang

Actually they aren't hex; they are expressions using pre-processor
macros. However the value and index arguments are hex (0x01 and 0x0);
they could be changed too.

It doesn't really matter. If it were up to me, I'd change the code in
usb_stor_euscsi_init also.

Yes.
