how to decide M483 HSUSB descriptors
Posted: 04 Aug 2019, 19:38
Hi,
we use M843SIDAE as for a usb 2.0 device, the initialize of clock and register etc are correct, but when communicate with host, the error occurred:
" usb 1-6: device descriptor read/64, error -71
usb 1-6: device not responding to setup address
usb 1-6: device not accepting address 7, error -71"
and the example in the bsp and independently examples are all for M487JIDAE,
i can't decide whether the usb descriptors parameters such as "idProduct" in the examples could be used for M483SIDAE?
And if so, which parameter(s) or setting(s) cause the error?
could anyone help me?
Thanks very much.
