the version of linux kernel is 2.6.11.6 and host control chip is isp1561. Main chip of system is pnx8550, which has one mips core and two dsp core.
Now while plugging some usb disk, there are error messages.
the dmesg inforamtion is as bellow.

What is problem? how to fix it?
thanks!
USB work still happening
I'd seriously consider upgrading your kernel if you're having problems. There's always new USB tweaks going on. There are known issues with USB-Storage that are actively being worked on and fixes keep going into new kernels.
Re:USB work still happening
Thanks!
I have considered upgrading linux kernel. But my system is based on embedded mips chip. Kernel porting is chip manufacturer work. If I porting new kernel, there are some problems.
if not upgrading kernel, do you tell me some method for fix this bug?
Thanks!
