I might have been unclear. I do this with my N810 and I don't watch the video on the NIT - just use it to offload recordings to a HDD.

PS The N900 playback quality will depend how well we can use the DSP and other extensions - the OMAP34340 should be very capable of 720p if the extensions are fully utilized.

Not even a N800 or Soekris? Zomg the world is collapsing! :eek:

This thread should be added a prefix: Incredibly silly because after a few pages it does get there quickly.

I'm buying this for completly other reasons than having USB-OTG etc.

That said:

"Living in the past because no WiFi(or don't want it)" - a) unsecure b) tedious to setup c) unable to debug Air[TM] ERROR d) unreliable

"Using Serial<>BT" - I find this an excelent idea. Makes it easy to not need crawling around etc. The one downside I see is: farraday cages - a lot of those racks are more or less near such so it would be rather difficult I think to get through.

"Alternative to flash dongles" - a flash dongle that uses a microsd is what I would have expected the usb dongles to be from the start. Sadly none of the manufacturers bothered with it. I tend to have with me atleast 2 microsd cards with adapters for minisd and plain sd and a smallish microsd or plain sd card reader. The problem is when someone just wants for you to copy things from their key to whatever device. I would make it clear I expect only such and such format(considering what mail I autoreject just due to attachments this wouldn't be much of a prob for me). Not to mention all the possible filesystems etc. I don't carry around anything FAT formated.

So yes might suck, might be hackable but the main reason I want this device is:
It's a portable device I can use as a dumb terminal and has a phone bolted on.

I'm not a heavy phone user so the first bit is for me the big deal.

Mwah. Instead of WPA2 you could run a VPN (OpenVPN, SSH, IPsec) over it.

True, my suggestion is not meant for long distance through the server room, but it still makes the N900 'mobile in the hand' so to say. Ie. you can perform a pirouette without tripping over a cable. And given some devices are only accessable via RS232 its either RS232 or RS232 <-> USB/BT/??? adapter. Although the issue I thought of was the insecurity of BlueTooth.

****, I cannot agree more.

Almost none :)

Miutech's HDPC will have 2 separate USB connectors too. And Ethernet! But it's a bit larger than the N810.

Or if you are truly paranoid WPA2 "enterprise" (certificates) with openvpn.

Yes I really am _that_ paranoid! I've even thought about getting that anti wifi paint for my house! lol

Perhaps from a low-level point of view. But you can have protocols to do whatever you want, i.e. this is a software (firmware) only problem. FYI, I could connect my Zaurus (USB client) to my laptop (USB host) and control everything from my Zaurus. More precisely, I had an IP connection via USB between the two devices.

And you're back to step 2... tedious setup ;) And of course you might have the horror of having one of those wifi cards that just loves to randomly bring down the entire system.

You know, I really don't have to justify my preference. It's not inherently "right" and you might even be able to define it as "wrong", but it's still my preference and that's what I'll base my purchasing decision on.

But, since you ask: I have a 16 GB card in my pocket computer, and a 32 GB flash drive in my pocket. Obviously, the flash drive can hold more than the pocket computer. Sometimes I want to access files on the flash drive. Do you seriously think I would choose to go to a desktop computer, transfer the files I need from the flash drive to the desktop, then from the desktop (DIRECTLY! -- as you put it) to the pocket computer?

Thanks, but I'll wait for a pocket computer that actually fits my needs, rather than adapting my work to a poorly designed (in terms of meeting my needs) pocket computer.

HOWEVER...



At least the publicly available OMAP35x (similar to but not exactly the same used in N900) technical reference manual lists USB2.0 TESTMODE register. It appears that it could be used to force the controller into a specific mode by software, regardless of the ID-pin or connected devices.

The N900 might not deliver power to the port but other than that I still believe the support might be doable by software hacks.

I have also believed that support might be doable by software hacks. Thanks for providing some tech info.

...or not. :p

What wasn't very clear to me in all this discusion is:

Can the N900 simultaniously charge and transfer data when connected to a desktop or other computer via USB?
