Hi, all
Recently, I want to develop the Human Interface Device part (e.g. USB keypad or mouse) in 6446EVM in order to let the users interact with our apps. However, after the USB slave was connected and the board was powered on, the power LED on the USB slave only flashed one time in the booting process and seemed not to be powered from then on. In the /dev/..., there are 2 devices related to USB: usbdev1.1_ep81, usbdev1.1_ep00. I really can't handle this and hope you can help.
The boot info and "lsusb -v" info are attached below.
Thanks in advance.
