Re: USB/IP - a way to connect USB devices to your N900
 

nice picture, but don't underestimate the problem:
it would require a chipset which runs Linux 2.6 and is fast enough
to handle the transfer speeds. This would be a non-trivial engineering effort.
The chargers and batteries, however, are low-tech, low-cost, disposable devices assembled in China.
It would be better to keep the USB/IP hub as a separate device which could
be connected to any USB micro power source.

Re: USB/IP - a way to connect USB devices to your N900
 

But wouldn't you like to have the USB/IP portable? I know that the device pictured is too small to be accurate.

I was thinking about some sort of wireless self-powered usb hub that would allow charging too if that would be needed.

Re: USB/IP - a way to connect USB devices to your N900
 

yes, it should not be larger than the N900 itself and should have it's own
battery. Input voltage range should be such that you can connect both
LiPoly and normal AA cells.

you mean wireless charging? :D that would be nice (Tesla would love it).

I think a wired connection to the N900 should be default
(as if the the hub was a desktop computer) and wireless could be optional
(it's probably too slow).

Re: USB/IP - a way to connect USB devices to your N900
 

What i am thinking is that the device should have atleast 2 USB ports, 1 Ethernet port, chargeable as well, builtin wifi transmitter which will ofcourse transmit USB data as well as internet (received through ethernet). The size could be like as normal wireless router available in the market. Usb port should also be able to charge N900. The batery life of the devicse should be atlease 3 to 4 hours.
Is it possible :-)

if you can afford it (shipping is about $50 to EU :(

would even give you DVI output.
now you only need to provide 5V input, e.g. http://gizmodo.com/gadgets/gadgets/m...ger-177527.php

Re: USB/IP - a way to connect USB devices to your N900
 

are the first 2 devices compatible with N900?

Re: USB/IP - a way to connect USB devices to your N900
 

not without some hacking.
you would have to install a Linux kernel with USB/IP enabled on the flash mem.
(it's almost the same chipset as on the N900 - so could even port Maemo to it)

for power supply you could also try

Re: USB/IP - a way to connect USB devices to your N900
 

Don't know why I got stuck at the idea that USB/IP *has* to be done over wifi.

If it works by pluging it in directly we should keep it simple and small IMHO.

Once we have a working full-size "female" USB port all imaginable adapters and converters could be plugged in.

Provided you know how to mess around with the N900 kernel and wire those two boards together and to a decent Li-Po power source + charging circuits, the rest would be a piece of cake.

Re: USB/IP - a way to connect USB devices to your N900
 

is there any chance that these devices be available in an assembled form for N900 in the future?

Re: USB/IP - a way to connect USB devices to your N900
 

step by step - first we need to verify that USB/IP can work in the N900 kernel
and that the speed over USBnet or wifi is sufficiently fast.
Then it will be a DIY solution until someone is willing to mass produce it.
