Try setting size to 64.

Try setting size to n * 64.

The request timed out (cancelled by the DLL). The device either didn't send any data
or your timeout value was too low.

Re: [Libusb-win32-devel] "-ETIMEDOUT: Error -116" on successive bulk_read

[amol s. <amo...@gm...>]

Thanks, Stephan. It appears to be working fine as soon as I set the size to
a multiple of 64 and increased the timeout.

[Libusb-win32-devel] trouble installing libusb driver inf

[Thomas S. <th...@th...>]

I get an error when I try to install the device driver for my device.  By
default it comes up as a USB Audio Device, but I want to change it to a
libusb driver, obviously.  I do the "update driver" from Device Manager and
browse to the inf file created with the inf-wizard, and then get this error:
 
"specified location does not contain information about your hardware"
 
If I uninstall the device from the device manager, unplug and plug it back
in, it has an "!" for a little bit but then returns to a USB audio device
within 30 secs.
 
Any ideas what's wrong?
