Tool/software: Linux
Hi,
Our USB device (based on Cypress FX2LP controller) keeps getting disconnected when connected directly to AM3352 USB bus. At first, it disconnects and reconnects successfully but after a while (a couple of minutes), the device stops accepting device address.
Moreover,
The USB device works properly when connected to the bus via a USB hub.
And, other USB devices are able to connect directly to that bus.
Below is the dmesg log:
