Re: N900 will not allow USB OTG!
 

Personally i find some of the "cmon you don't need usb otg" posts pretty useless, since they don't add anything to the search for a solution or extra information about the issue.
If I'm posting here it's because I find that feature important.

My use cases:
- I have a 1 TB HD with many movies, many MP3's, software, documents, images, whatever. I keep pretty much on there. And I assure you 32 GBs are not enough. Space is actually never enough :o
So, If I want to place a different music selection on my N900 for a party or travel, I would just have to attach the HD to the N900 in host mode. No intermediate steps via my shutdown computer.
- I could attach a USB DVD reader when needed; I never needed it so far, but hey, to have that possibility more would be great. Like not having bluetooth till you discover you could really use it for once; it's added value.
- At home I only have wired internet (ethernet). And I don't want to buy a wifi router; I'm fine like this, I love ethernet. So, no USB-ethernet adapters.
- USB flash drives (often at university)
- attach my digital camera
- USB keyboard or mouse eventually when needed

Many things you can do with a USB host. None of these it it's missing. The bluetooth-USB, if it exists and works, would always need a source of power (while, if I'm not wrong, the N8x0 has enough power for flash drives, probably my digital camera, maybe keyboard, maybe mouse.. dunno whatever; some not, but for those I would find a cheap and small self powered USB hub). The transfer rate is slowish, but well, compromises and patience I guess.
Still, we have to find that bluetooth adapter, not sure if it exists.

Re: N900 will not allow USB OTG!
 

Of course I have some options:
1. N800 + small cheap phone
2. N900 + N800
3. Laptop + phone

But this would be even better:
4. N900

I don't want to maintain a laptop or N800 and another phone: updating software, charging batteries, old-battery replacement, managing power-cords. Yuck! I don't want to carry them, boot them, debug them.

I want something that will fit in my pocket and do what the N900 does + USB like the N800.

This device should have two USB ports (If Nokia cannot provide the functionality expected from a "mobile computer" with one port).

MicroUSB converter for USB sticks http://www.allaboutsymbian.com/revie...Mobidapter.php

Perhaps not in your case but in other cases partners could use USB sticks which host (micro)SD card, or use a SD card hosting microSD and having USB connector.

BlueTooth to RS232 converter http://www.serialio.com/products/ada...BlueSnapXP.php my OBD-II reader also came with a RS232 to BlueTooth converter.

Re: N900 will not allow USB OTG!
 

I have to say that after thinking about it, MOST use cases and features of the N900 negate the need for USB host. But if you already invested in USB devices for the tablets, its going to be a really hard decision.

I just use USB host for my mouse/keyboard, which have bluetooth alternatives. Actually, most things can be used with bluetooth or bluetooth serial. Just not everything...

Re: N900 will not allow USB OTG!
 

Yeah, I believe this is sadly the voice of the majority so the compromise makes perfect sense for Nokia. Hard cover, two full SD slots, buttons, d-pad, usb host, ... who needs it anyway. And this is step 4. I wonder what the step 5 will bring us :-)

when charging over usb, whole usb port might break easily. One hole and a pin seems more robust to me. I wonder how long microusb will last when charged daily.

Yes, HTC phones. They are one step ahead. They managed to put audio into usb port too so you cannot charge and use headphones at the same time unless you buy special bulky cable. Oh, wait, you cannot use your regular headphones even when not charging without using special adapter too.
Definitely. It is great to fit into planned target group :-)

Let's hope bluetooth wil not lag on N900 so it will be good alternative for keyboards and gaming.

Re: N900 will not allow USB OTG!
 

I love Ethernet too, but seriously, take a look at something like the Cisco/Linksys WRT54GL. It has a Linux OS that can be flashed to a custom enhanced version; it's a great Ethernet router; plus it does rock-solid, secure wireless.

Re: N900 will not allow USB OTG!
 

Robustness shouldn't be a problem. Mini-usb has the contact springs in the device, but the micro-usb connector moves the springs to the cable.

Micro-usb is much more robust than mini-usb, and if problems develop the chances are that they will be fixed by a new cable instead of needing a device repair. Micro-usb is a reasonable choice for a charging connector.

discussed in the first pages; just look at where the SD card slot is in the N900... ;)

Re: N900 will not allow USB OTG!
 

Mobiadapter looks great! But can I use it with N900 because the location of the reader. I guess that reader in N900 works like sim reader so I can't see a way how to put mobiadapter in.

The problem with Enttec is that the device itself works via usb but OS thinks it's a serial device. That's way I need somebody's help to get it work straight over serial or then I need a new device that sends dmx over serial without too difficult h4x0r ;)
