[News] Poseidon licencing ceasing on 01-Aug-03 | ANN.lu |

Due to reasons I will not explain here further (ask me in private),
Poseidon keyfiles cannot be bought after 01-Aug-03. People having just
bought an USB card, that does not come with an OEM Licence, have the
chance to register Poseidon until the end of this month.
Support for existing users is NOT affected and will continue as usually.
It is recommended that dealers stop selling USB cards without licence to
avoid angry customers buying an useless piece of hardware, until the
vendor delivers his own software solution or the situation is solved
somehow.

Poseidon licencing ceasing on 01-Aug-03 : Comment 90 of 94 | ANN.lu |

It is not a question of viewpoints. Product specification, the Algor card in this case, is not a literary work where everybody can have one’s own interpretation, irrespective of intentions of the author.
Algor is a USB host controller. If a USB host controller is compliant with the USB 2.0 specification, it MUST provide High-Speed mode (USB 2.0). As Algor *does not* provide High-Speed mode, it means it is NOT compliant with the USB 2.0 specification. Algor is compatible with the USB 1.1 specification at the most. This is a USB 1.1 host controller. Period.
Quoted after www.usb.org Nomenclature Site:
'All USB 2.0-compliant systems, such as laptop, notebook, and desktop computers, must by definition support all three data rates: 1.5 Mb/s, 12 Mb/s, and 480 Mb/s.'

You are wrong. USB 2.0 specification does not specify speed of the computer in processing data coming from the USB 2.0 controller. The USB specification defines speeds of data package transfer, which are to be obtained between the USB controller and USB devices.
> I have not seen a clarification on this issue in Elbox website.
Why you think Elbox should respond in their website to messages from Highway ML? They responded to the message which you cited on the Highway ML. See here: http://groups.yahoo.com/group/highway_usb/message/144

There must be some misunderstanding.
Data transfer rate between SDRAM/SGRAM memory in the graphic card installed in the Mediator slot and Fast memory in the turbo card is NOT limited with the Zorro-2 Bus standard.
In Mediator systems, this rate depends on the design of a given turbo card, reaching from 8 to 18 MB/s for the currently available Amiga turbo cards."

> They state too that Spider is USB 2.0 Hi-Speed (480 Mbits/s) compliant. Why don't you complain also about this?
Because Spider PCI card is High-Speed USB 2.0 compliant. |
