I've built a project using a custom board , which has a HID Generic Interface device built using the the Start ( ASF4) Previously I also built a project using a SAM D21 using Start with a HID interface with no problems.
Anyhow my problem is this. First, without any modifications , the firmware would not install usb_d_inst.ep .hdr 2. which is Endpoint address 0x01.
I was able to do a slight mod to get it to install. Now although the USB device shows in USBview and enumerates successfully. I can not send any data to the device. I am getting a WriteFile error in windows . My USB protocol analyzer also shows no packets are being sent. I realize that the S70 has a highspeed USB interface and there are many more configuration options and register, but I thought Start would take care of that. Has anyone out there run into a similar problem ?
I can provide any more information if it helps.
