Deneb Ethernet Driver

 I believe the driver I am looking for usbsixeth.device I can not find it anywhere on my computer. Any ideas?

The driver usbasixeth.device is generated in memory only.
You should see it with scout in the device list, but *not* on disk, so just enter it without any path name (like devs:).

BINGO!!!!  I am up and running... Thank you..

You're welcome.

Oh. By the way, you can find such information also in the nice AmigaGuide file delivered with Poseidon:

To the AmigaOS the USB device is available through the  "usbasixeth.device" SANA-II device which is created in memory during runtime.
Hence you will not be able to find a file based device in DEVS:Networks as usually expected.

RTFM :-)

I tried a cheap $5 one off ebay that I couldn't get to work, but then again I didn't give it a lot of effort..

Chris worte a new driver for such "cheap" (and I mean cheap in price and design) adaptors on a user request... so chances are good.

Send me the psddevlister output (or at least ManId/ProdId) of the ethernet dongle, and I can tell you :-)

Using a cheap PC Ethernet device instead of a Zorro based card means that the Deneb almost pays for itself immediately.

Which is one of the reasons why the RAPTOR never made it into production, but was dropped in favour of the DENEB during development :-)

What's the difference between doing that and the TCP/IP hardware offloading provided by some server hardware?

From the hardware side of view there are chips which exactly do that for you, in case you want to easily adopt an FPGA to some ethernet connection (like WizNet family of ethernet connection chips).

My experience here is that you lose in speed, but gain in ease of use (as FPGAs don't have CPUs, in most cases).

Where you *really* can gain in TCP/IP speed is checksum checks and calculations, as those operations are tailored for serial data streams in hardware, and CPUs have no chance to keep up.

But these things are already done by the DENEB USB controller chip. In fact, there are solutions like those you want to do (e.g. from FTDI), but they are limited to USB1.1 and offer no real performance - besides the problem, that due to restrictions in RAM and ROM of the uC you cannot support all classes at once, and you are bound to the USB stack given by the IC manufacturer.
