Sure. I think my point is that I've seen this problem on both of my
units when powered by both a 5V2A wall adapter supply and a 5V.8A
supply. Since the problem has been reported by other people it's
sufficient for me to look to other solutions that don't h

Don't hot plug USB devices directly into the PI, if you must hot plug

Sorry, I should have been more clear. I saw 3 ethernet ports on the back
of the 4501. So I thought a 'net switch would be a way to get more of
those ports at the location of the Pi. That's all.

That's not my reason.

That's not an equivalent for my needs.

Newegg has a refurb'd netbook for $40 right now and new ones for $100.
These are complete systems with LCD display, case and battery power with

the pi, Ardurino, Launchpad or whatever is if you intend to "hack" the

The net4501s went way up in price, but there is a seller offering a lot of
five net4521 boards plus five 64MB CF cards for $80 - and he is willing to
accept less if you make an offer. Try lot 320744604969.
They seem to be the same as a net4501 but with two PCMCIA slots. I was
gonna try to run NTPd

A variation is still available for sale from Soekris and they're more
than $129. However I don't think they're worth buying from

What do you need to know? Most of the details will depend on what
software you are running on it. Which operating system. After it boots up
you can look in one of the log files. But details vary with the OS.

Do you have any documentation on how to use them? I have one that I
bought to be an internet access point with a verizon card, failed due to
verizon not complying with the RFCs. Love the device, but no
information on ports, etc. Might want to play with it, or could make it
available.
