There is a discussion on EAB:
eab.abime.net/showthread.php?t=66255
That involves two hardware solutions to the lack of available USB devices for our Amigas.
The first is a small USB 1.1 controller for "bedded" devices referenced as: item.mobileweb.ebay.co.uk/viewitem?itemId=251042721473
The chip was used in the Thylacine USB board made in Australia which has been posted by the original designers as now "open" to the community with schematics, software source code and drivers. It originally had its own stack but uses Poseidon well. It works in OS 4.1. It is proposed as a project that could be built and sold in Zorro and clock port versions by "do gooders" who want to help out the Amiga community and maybe could use generated funds for other projects. The cost of the components for both seem inexpensive.
The Thylacine information is below:

Count me in as a buyer if someone will build it
-
AFAIK the SL811 chip used in Thylacine is quite unstable (according to experts like Chris Hodges, Jens Schoenfeld, Michael Boehmer and many others).
Rubbish is cheap but it's still rubbish.
-
A cool thing to do would be to write a USB/IP (http://usbip.sourceforge.net/) device driver for Poseidon, so any connected Amiga coputer could use USB devices shared from other computers.

That looks interesting. Will have to give it a nose.
Could be really usefully on my X64 machine anyway

That is a surprise to hear. My Thylacine card seems very stable and works with printers, mice, keyboards and thumb drives. In fact the Thylacine.device lists Chris Hodges as having put the final fixes to it in 2004. I've read where a lot of people used it with Epson scanners and loved it ( my Epson scanner is still packed from a recent move). Could it be a problem with USB 2.0 devices? The USB hard drives and 100 MBit/s NIC's might be slowed, but do you think there is data corruption with them? I've only had positive experiences, what details have you had that show it is "rubbish?" Could you list the references to those comments to pin down the problems?
-
These are really GOOD news, especially opening sources and schematics: thanks!
-
a replica, or rather improved followup is already being attempted here:

Really? Can you tell us what it says, it appears in German
It would be most desirable in a Zorro and a clock port version
-

Me too!
-
Looks like the clockport already have all the needed pins.
-
Or jens could do another run of deneb and subway.
Just sayin'
-
true, but take a look at the price.
If it could run as-is it would be the cheapest USB solution for classic amigas.
-
I don't think Jens had made the boards for E3B -- Deneb although they work together on PCB boards for Subway

Carefully look at Errata number 1 (I've got no idea if the SMD hub chip crasbe is going to glue onto the board his this "problem", but if it has, then no mice or keyboards will be working) and number 6 (not that the other ones aren't bad, but the last one would make me refrain from using any MSD devices with it!).

I would guess that wouldn't pass initial tests, so he wouldn't use that chipset. Something to be aware of tho....
and number 6 (not that the other ones aren't bad, but the last one would make me refrain from using any MSD devices with it!).
It sounds like that's just something to be aware of for the USB stack (don't use "auto-increment"). I don't see how this affects me at all..
The performance of USB (especially over clockport) is probably going to be throttled by many other things before this would cause an issue..
And remember, this is supposed to be low cost, so slower isn't a big deal. People who need more speed can buy the more expensive faster cards. ;-)
So, I don't see any major issues holding this back..
Looking forward to a possible clockport version.

AFAIK he has not planned to do too many iterations.

This is not a clockport card, but a Zorro card. 95% of the CPU time is spent in the copyloop for copying data to and from the USB chip for any card (except for the Deneb in DMA mode, where, hence, the Buster will do the copying) -- at least with bulk transfers involved. The current driver implementation of the Thylacine uses the auto-increment mode. The workaround (in the HCI driver, not the USB stack BTW) as stated in the errata would AT LEAST halve the speed of the data transfer on an already slow 8 bit interface. In my eyes it would render the mass storage use case useless.
So, I don't see any major issues holding this back..
Sometimes I wish the Amiga users wouldn't be wearing those reality-warping glasses.

The very first Subway prototype used the SL811HS chipset. After experimenting with it in March 2001, it was found completely inadequate and unreliable and was abandoned in favour of the UHC124 chipset (both used on the production version of the Subway and Highway).
-
Could you remark on the unreliable and inadequate statement? It seems to work on the Thylacine card for 1.1 devices. When there are no solutions out there, even a compromised one is better than none
-

Yes, but as I said, I'm hoping for a clockport version.

However, not all Amiga owners see things thru your eyes, hence there are multiple solutions.. At least half (maybe slower) than it "could be" is still better than no USB (or so expensive that they can't afford it).
Sometimes I wish the Amiga users wouldn't be wearing those reality-warping glasses.
Funny, I'm looking at my office, and I see an Amiga 1200 that wouldn't care about "half the speed." I think that Amiga is real..
Hold on, let me check...
Hmm...
It seems real.... ;-)
Or do you mean because you "require" it to be faster, that anything that isn't faster is wrong for everyone else?
I wasn't saying this would be the best card ever...
I was saying that even with it's drawbacks (which I admitted are there, no "warped reality"), there are plenty of people who could enjoy it given it's possible price point.
I wasn't saying it wasn't a bad solution for you. Just that it might be an OK solution for other people..

Folks,
Build a better mouse trap; I will buy one! It can't all be a"bust." Just charge more. I mean have you seen the prices for stuff these days, and I'm still in line
-
A check of the postings show major work under way with one card sporting an Ethernet interface. Moma's makin' some gravy now!!
-
I've had two NEW Thylacine cards for a week now from the amazing Genny_Flick. They may only support thumb drives, mice, keyboards, printers, scanners, and Asix based Ethernet dongles, but even with the slow 1.1 speed for €91 or $121 or £78 it is a great investment.
We should all support our own community and display more purring and less hissing.
-
is there a thread on AmiBay for these?
-
Yes.
-
The Thylacine re-developer is working on a half-size board of this USB board.
-
Is there any hope of another run of Subway or Deneb cards in the future or is that thought a futile one and, if so, why?
-
Deneb or Subway? Ask Michael at E3B. But Jens should have an anouncement about his X-Surf 100 with 100 Mbs Ethernet and USB onboard.
