Very Computer

Hello, I think about something maybe interesting :
USB is 12Mbit/s capable.
Is there an easy solution to connect to PC under linux with USB to USB,
like SLIP or PLIP?
It should be fast enought and cheap for a point to point connection .
Perhaps 16550 are able to do fast jobs too .
Is there a project to develop USB support inside kernel ?
All informations are welcome
TIA

At least in theory.

Not at 12 Mbit/s. Get a couple of inexpensive NE2000 clones, and you'll
be happy. I've had good luck with the Kingston cards.

The latest Triton II chipset now supports USB. There's a USB connector
on my Tyan Tomcat motherboard that I would love to use.

My question is: Is there any work being done on creating a USB driver
for Linux?

Not yet, I think.  But I have managed to download the PIIX3 datasheet

GMT+1) - usualy www.intel.com is simply too busy (connection times out
etc) to download stuff.

My new 430VX motherboard as USB support too, but it seems they (Soyo,
the motherboard manufactor) "forgot" to but USB connecters on it!
Besides that, the board works like a charm (did a full kernel compile
in 9min 30sec).

(From memory)
Stepping A0 : No ECC, No USB
Stepping A1 : ECC, No USB
Stepping B0 : ECC, USB
This means that if you have a Ax stepping of the triton chips that you will
never have USB on your motherboard, so it would be very useless to put
connectors on them.
I bought my mb (Acer AP53) here in Belgium 1st half of July, and it is still
a A1 stepping, although at that time there were some postings from
people that had a B1 stepping (on ASUS boards I beleive).
I wouldn't be surprised that it is only now that B1 boards are shipping.
And that a lot of manufacturers keep these mb until all the older ones are
sold.

It is of course a rip off, but I am sure that PCI USB adapters will be
available soon (I've seen at least one ad for it). These might not be
on you mb, but who cares for that.

Greetings,

Ron.

That's assuming everybody sticks to the USB specs :-)

: But why can't there be something like a 12 Mbit/s null modem
: cable connection two USB buses on two different PCs?

Because its not a serial cable, its a BUS. And a bus has a protocol
which runs across it. To be able to have two computers on one USB
line you would have to have one of them configured to not be the
"HUB" as the other post refers to it. Specialized software, maybe
not possible at all depending on the assumptions made by the hardware
makers. In this case, with Intel making it, you are probably out of
luck. (I don't know this for a fact)

store:
Buy 2 ethernet cards, 2 50 ohm 10base2 terminators, 1 piece 10base2 cable

cost? $50?

: following up on an article I read recently, the Motherboard provides a
: ROOT USB hub.  There can only ne ONE root hub  per USB bus and hence
: it's impossible to network 2 PC on a USB connector :=(

Feh.  Get FireWire.  100-200Mbps right now, with the potential for 1Gb
in the near future.

   I believe there are two chips, one responsible for ECC, one responsible for
   USB. I've only seen motherboards with USB support but not with ECC.

This is correct.  The ECC stuff is in the 430HX chip Host Bridge,
while the USB controller is in the PIIX3 combo chip (PCI/ISA bridge,
IDE controller, and USB hub).
