Re: Help with talking to a device

["David Hooker" <dhooker@xxxxxxxxx>]

Ah, thanks.

Changing my timeout value to 1000 doesn't help, though.
I'm in contact with the device manufacturer - maybe I'm
doing something else wrong.  Being new to USB development
I wasn't sure how to go about debugging this.

Thanks.

Because the polling will occur automatically every 10 ms without your 
program doing anything, until the request times out or the device sends 
some data.
