Hi,
I have got a usb device connected via usb hub (LAN9514) to the OSD3358 processor (Debian 4.14.93-bone17.1)
After few restarts of my USB device connected to the OSD3358 I receive error:
[ 6992.492407] usb 1-1-port3: unable to enumerate USB device
After that the only way to make it working is to:
rmmod musb_dsps
modprobe musb_dsps
What could cause this situation? Is there any patch or any way to avoid reloading whole usb bus?
I tried with no effect:
echo "on" > /sys/bus/usb/devices/usb1/power/level
echo "on" > /sys/bus/usb/devices/1-1/power/level
echo "on" > /sys/devices/platform/ocp/47400000.usb/power/control

It looks like the dsps_interrupt (musb_dsps.c) is not called when device enters this state.
In the normal condition, we start the transfer, and straight away interrupt is called:

We use Keysight oscilloscope to decode frames and trigger on "80:06:00:01" sequence. Normal restart procedure seems fine, the oscilloscope triggers the data sequence, however when the system enters fault condition we no longer see oscilloscope triggering.
We tried to log traffic with usbmon, in the fault condition "GET DESCRIPTOR" request fails with this status:
URB status: No such file or directory (-ENOENT) (-2)

The problem doesn't appear when we set the maximum speed to 'full-speed' in the device tree. This isn't the solution for us due to a high-speed device connected to the same bus.
&usb1 {
status = "okay";
dr_mode = "host";
maximum-speed = "full-speed";
};

Has a different brand of USB hub been tried? I could see some hubs

We are certain that the LAN9514 operates on high-speed where it can and on full-speed on ports where a full-speed device is connected. We can decode only full-speed frames with Keysight, we don't have a tool to sample and decode high-speed traffic. We tested only LAN9514, this is what we have on our custom PCB.
Based on the usbmon we can tell that 'descriptor request' is sent, based on the Keysight oscilloscope we know that this request doesn't reach the full-speed device. Is there any way to reset single USB hub port from Linux? We know that the problem is recovered when the musb_dsps module is reloaded.
Please find usbmon captures attached.
