This topic provides a brief overview about USB bulk transfers. See how Fairfax County uses Fillout forms to increase operational efficiencies and save staff time through automation.I have for a long time been wanting to do a Custom USB class driver on the RT106x devices. Each USB transfer is one packet, which can be up to 64 bytes if using bulk type. If you want to send more than 64 bytes, you have to use multiple packets. Requests on bulk endpoints can be sent synchronously via UsbDeviceConnection. BulkTransfer() OR asynchronously using a UsbRequest instance. In this topic, you'll learn about a USB bulk transfer and how to initiate a transfer request from your UWP app that communicates with a USB device. I'm attempting to use bulk transfers to use the maximum allowable amount of free bandwidth when the bus isn't busy for data transfers.
