Hi,

It doesn't look like the full log came through. (Please remember to compress it.)

Zipped and attached.

What if you set the USB_DEBUG environment variable to something non-zero? Do you get any more debug information about the failed transfer?

I did that and hid_set_usb_debug(1) in my code. No extra messages.

I have experimented with a number of timeout options. Short, long, very long. So I do not think this is because of the time the device needs to process the second command.

What is "very long"?

Several seconds.

Also note that there are seven seconds between these transfers:

That is because they are sent manually from a cumbersome demo-program ;-).

Nonetheless I put a ten second delay in my code between successfully receiving the reply to the first command and sending the second. No change observed.

Ciao, MM
