Gentlemen,

What are the possible ways to get a high speed (i.e. 480Mbps) USB bus on Zaurii?

NO, hardware limitation

12Mbps is USB 2.0 OTG is part of the USB 2.0 spec what you want is "high speed" which i think should be called "full speed" as its backwards to me

Duly noted and corrected, thanks. I always mix the two of them.

Anyways, really, no way of pulling it? What about CF USB cards and stuff like that?
Or anything... Anything!

=P

Well if you can get the drivers down... then yes... if the CF usb card support 2.0 and OTG you will get 2.0 speed... as long as it has the "high speed" usb otg bridge...

I don't think there are many usb CF cards. I have a ratoc and it's only usb1.

Think about...

The cpu does not manage the throughput.

Da_Blitz · « **Reply #6 on:** November 01, 2006, 06:56:53 am »

actually you would max out the CF bus as well, i wouldnt expect to see high speed throgh a CF card

i have seen a NSLU (same proc at 233Mhz) max out a usb 2.0 link while transfering the data over 100Mbit lan so its not really an issue of cpu speed

How about a CF->PCMCIA adapter + PCMCIA USB2.0 card?
I don't want/need full 480Mbps, just more than 11Mbps (mini harddrive+wifi+VGA card, maybe also LAN and BT). What I'm actually planning to do is to make a snap-on 'dock' for my Z, with this stuff and an aditional battery. And don't tell me to wait for your OpenPDA cuz I don't want to pay for it with my first pension check. =P

PCMCIA USB2.0 card

I doubt these exist, in fact I doubt even USB 1.1 PCMCIA cards exist, they are all PC cards which aren't the same.

It's my understanding that "PC Card" is what PCMCIA was renamed to.

EDIT: I read a bit further down and it says that the name changed when version (type?) two came out. Sorry.

PCMCIA = 16bit
cardbus = 32bit

The zaurus implements a pcmcia interface, so you're 16 bits short

hahha, i love it how PC card vs PCMIA and USB 2.0 keep on comming up, prehaps we need to sticky this somewhere
