You are right. This function had a small bug that I fixed some weeks ago. The new version is in already the CVS.

Can you always guarantee that the last packet your device
sends is 11 bytes or less? If not, then set BUF_SIZE to a multiple
of the endpoint's buffer size. Otherwise your device might produce
'data overrun' errors (this may cause the -5 error you got).

You forgot to free 'context', call usb_free_async().

Where do I find out the file that keep a list of error like -5? And how can
I enable the usberror output? I guess I have to have the DDK to recompile
it? I don't have the DDK installed.
I cannot use multiple of 64, because there is the only way to detect end of
the packet. Each block is 64bytes, if the block is not 64 blocks, that means
it is the last block. This is the only way in the device I am using. Maybe I
am missing something.
I think I might have some hardware noise problem. Because I did not see the
problem on another hardware.

You can set an environment variable USB_DEBUG to 1 or 2 for debug
messages. Also the C header file errno.h may give some clue as to what
the error numbers mean.

That's libusb's error.h. I meant errno.h from the compiler's standard
headers - maybe I wasn't as clear as I could have been. MinGW has a
comment by each value here, can't comment on how helpful other compilers
might be:
#define EIO 5 /* Input/output error */

You can use usb_set_debug(255) to enable debug output. You don't have to recompile anything. Also, get DebugView from http://www.sysinternals.com/Utilities/DebugView.html This tool allows you to monitor the kernel driver's and the DLL's debug output. > > I cannot use multiple of 64, because there is the only way to detect end of > the packet.

If you are using a multiple of 64 you can still detect the last packet. The usb_bulk_read() function returns the number of bytes read. If you request 64*21 bytes and your device only sends 64*20+11 bytes then 64*20+11 will be returned. > > I think I might have some hardware noise problem.

usb_reap_async(context0, 5000);is waiting for the OV event. How would I find out how many bytes were actually read?

Stephan,
in usb_submit_async
if(!DeviceIoControl(c->dev->impl_info,
c->control_code,
&c->req, sizeof(libusb_request),
c->bytes,
c->size, &ret, &c->ol))
{
if(GetLastError() != ERROR_IO_PENDING)
{
usb_error("usb_submit_async: submitting request failed, "
"win error: %s", usb_win_error_to_string());
return -usb_win_error_to_errno();
}
}
return ret;
ret has the bytes_read. however, the value got returned before the value is
updated. I think usb_submit_async should take a parameter in as a
&bytes_read.
