Hi,
I have several TS-7250 boards and sometimes I experience a problem with
USB devices, that it's very difficult to reproduce. The problem is the
following: I have attached one USB HUB to a USB port (which port is not
important) and 4 USB devices to the USB HUB. It usually works fine,
however sometimes (1 time of 100/200) when the system boot it detects
the USB HUB but fails to initialize USB devices connected to this HUB:
usb 1-3.1: new full speed USB device using ep93xx-ohci and address 3

-110
usb 1-3.1: device descriptor read/64, error -110
The "status -110" should mean "timeout error" and "cc 5" should stand
for "DevNotResp".
The main problem is that a software reboot does NOT change the situation
and it seems that there is only one solution: unplug/plug again the
power supply. Unfortunatly, this is NOT feasible for our uses.
I actually have a board with this problem, so I can do some tests if I
do never unplug the power supply.
Do you have any idea, solution or workaround?
Thanks,
Marco Pracucci
P.S. I have attached the full dmesg (usb debug) log.
