well i myself have assembled this box. did i do something wrong because
it is running fine for last 10 months without any hiccups and other than
this minor issue no problem at all.

you can see it is detected as usb2.0.

actually it was i who sent it. i sent it through gmail so it did not
insert my name just my email id. usually i send through evolution. i did
not know this issue. apology for the unintentional mixups.
i want to know one thing - the hardware failing logic you earlier spoke
of - is that disabled or removed in latest 2.6.26.5 kernel because i
experimented with custom compiling that kernel and did not receive any
error message whatsoever.
