Mouse suddenly gets detached and reattached

[Bahman M.]

Hi all,

I just installed X (xorg 7.2) and am using FluxBox. It's working well
and there are no problems. However, the mouse gets suddenly detached
and immediately reattached. I can't say exactly how often this
happens, roughly about 6~7 times a day.

# dmesg | tail -n 4
ums0: at uhub0 port 1 (addr 2) disconnected
ums0: detached
ums0: vendor 0x05e3 USB Mouse, rev 1.10/1.00, addr 2, iclass 3/1
ums0: 5 buttons and Z dir.

# sudo sysctl -a | grep ums
dev.ums.0.%desc: vendor 0x05e3 USB Mouse, rev 1.10/1.00, addr 2, iclass 3/1

Is it sign of a problem? In fact I don't care about the hardware as it
can be easily replaced, I'm afraid that there's something wrong with
software.

Thanks in advance for your help.
