Hi,
I used to have a Deneb card for my A4000 and it was an amazing device and very fast...
I've heard there is a slow USB (1.1) card for the A1200 (Subway?), but is there anything that will give full USB 2.0 speeds?
Cheers,
Mike.

A Spider 2 PCI board from Elbox with the Mediator, but unfortunately it is not possible to register Poseidon for it, an even if you had an old key, it wouldn't work with the latest Poseidon.
Otherwise, you could use a Deneb with a zorro bus for A1200.

If the USB requirement is just for storage you can always go the PCMCIA CF Card reader option. Cheap and cheerful. If not fast.

The Subway is USB 2.0, not 1.1, but the speed is limited by the A1200's Clockport. So they're totally usable for USB pendrives, mice, keyboards, scanners, printers, card readers, guitars, rocket launchers, humping dogs and all those other USB gadgets we couldn't live without.
But as gertsy said, if you just need it for storage and swapping files between an Amiga and a PC it's best to use a PCMCIA SD or CF card reader, which is cheaper and much faster.

Hi all,
Thanks for the replies...
I'm thinking of something that would fit into the standard A1200 desktop case, so it looks like the subway is my best bet.
I do have a CF/PCMCIA adaprter, but it's good to be able to plug in USB flash drives and my external 2.5" USB drives...
Cheers,
Mike.

Meeeeeeep wrong !
The chips used on SubWay,HighWay and Algor are USB1.1 chips. The SubWay doesn't even reach full USB1.1-"highspeed" due to the limiting clockport.
But all USB2-devices have a fallback to 1.1 so there shouldn't be bigger problems except for the lack of speed.

No Kronos, the uhc124 chip used by Subway and Highway is a usb 2.0 chip but without high speed mode. Only low and full speed are usable.
The clockport is a bottleneck (8 bits) but the Subway react very quickly.
The OTG243 chip used by Algor is a true usb 2.0, got the high speed mode, but I doubt we can transfert anything at 480Mb/s...

Meeep WRONG! The ones on the SubWay are USB2.0 but they are FULL SPEED not HIGH SPEED!
P.S. I work for the company which make the UHC124 chips. I get them for E3B!

Awesome! Would you be so kind and check if revision 1.05 of UHC124 dataseet is the most recent available? This is the newest datasheet I've got from google search. Recently I did some hacking around NetBSD USB stack to bring USB support to NetBSD/amiga :). I'm in contact with E3B and I'm trying (well, "trying" is the right word here) to write a driver for SUBWAY controller. Having most recent revision of UHC124 datasheet would certainly help me.
