yes, I use a powered hub from the list of complient powered hubs. The
layout on the raspi circuit board for power supply of the usb is not
that good. So you loose quite some voltage on the printed circuits.
Hence the recommendation to use a powered usb hub.
It is possible and safe to use the
Thank you -
I have the latest RasPi which came out with 256MB RAM (I think it is called
Rev2 - with mounting holes on it, altered GPIO, and made in UK). does this
has polyfuses removed from USB?
I checked voltage between TP1 and TP2 - it says 4.84V
So what I'll try:

Hello Attila,
what kind of USB master did you use?
I am using the LinkUSBi and it is working very stable for more than 3
months on end (24/7).
I did post some settings I did to the raspi to make it more stable, and
I can 'dig out' those old posts here, in case you can't find them.
However
Szia,
There were postings about the w1 kernel module being unstable. Not just on
RasPi.

Martin,
thanks for your valuable comments. I agree not to upgrade anything once its
stable - I made a backup, so it was a kind of safe try... :)
And after raspi reboot - does it ALWAYS find the controller? My main
problem that mine is only sometimes, especially nowadays :( Syslog says it
has not
Vajk,
thx for reminder, Now I remember - that time I did not know what is w1,
this is why I did not pay attention...
So I need to wait, or find a stable USB adapter...
Kosz!

Oops, forgot to tell - I found your earlier comments, and seems you are
using a powered USB hub.
Does anyone know, if it is safe to power USB devices directly from the same
power supply I use to power the RasPi?
Eth0 - why you had to disable? I found a problem, when eth0 disconnect

you should use the same ground of your power supply to provide power
to your powered usb hub, if you don't do this, you should consider
some problems at usb data +- that anyone here could check easly
without your hardware
other option could be a isolated power suply and isolate usb data +-,

Unfortunately this is a Kernel Bug!

I would recomend using a DS2483, works best for me so far.
My schematic at http://home.geggus.net/pub/raspio.pdf includes an
additional IC for galvanic insulation.

Hello
First of all make sure you have the latest kernel run
rpi-update(google how to install it). This is a big improvement in usb
functioning.
I looked at the site and it seems that your adapter is an DS2483 with
some usb serial adapter. This is not a good solution. I personally
