I have a Tecom BT3030 USB dongle which was working fine when
connected to my 1200MHz Athlon machine. When I decided to put it on my
mail/web/etc server, which is a Pentium 133, I started getting entries
in kern.log like this:
Jun 24 09:00:37 cheops kernel: usb-uhci.c: interrupt, status 31, frame# 666
Jun 24 09:00:37 cheops kernel: usb-uhci.c: Host controller halted, trying to
restart.
I wondered about these for a while, but the device seems to work
well enough (for the limited use I have for it at the moment). A
Google search turned up several people with the same problem, but no
obvious idea of what to do about it (except for one suggestion to try
using the uhci module instead of usb-uhci: I tried that. and couldn't
get USB to work at all).
Today, however, I noticed that it seemed to have something to do
with CPU load. I get several of them when mail comes in (CPU load goes
up because SpamAssassin and some AV stuff gets run). I tried running
some programs to deliberately load the CPU, and was rewarded (if
that's the right word) with several more of the same errors.
Admittedly, the box is rather old, but it normally runs at very low
CPU load (except for bursts). It's quite adequate for everything else:
why would a USB dongle be so CPU intensive?
I don't know if this is a bluez problem or a USB problem, but I
thought I'd start here anyway. If people think it's likely to be a USB
problem, then I'll take it to the USB maintainers (whoever they are).
