Did you post the link? I would like to try it with my USB100M

jolouis - I have received three of the the mini USB B male to female A adapters that were modified to automatically switch between USB OTG and Host mode on the N800 IT. Unfortunately, the modification of the mini USB B male connector on all three of the adapters has left the shape of the connector somewhat skewed or mishapen. The mishape is enough to make it very difficult to insert the adapter into the Nokia tablet's mini USB B female socket. I may be able to force the adapter into the socket, but I am hesitant to do so for fear of damaging the socket on the Nokia tablet. Any suggestions? Anyone else face this problem and just pushed harder with no apparent damage to the Nokia tablet's socket?

Since I have not had the courage to push harder, I cannot report on success or failure of the modified adapter to automatically switch between OTG and Host mode.

Thanks
Steve

Steve,

Mine was a bit off too. But I just sort of gently worked it into the socket on the tablet now it's fine. I too was a bit leary then figured WTF and gave it another shot and all was cool.

When I looked at the adapter in relation to the socket I could see the "top" where the two edges of the metal come together were not quite even and every so slightly apart. A bit of gentle persistance and all was fine.

If you have another device with the same connector use that device to help "finish" the adapter shaping. Or even some gentle use of a pair of needle nose pliers should do the trick...

just a question out of curiosity. It's been bugging me and since I know squinto about the OS08 and/or Linux (though I was proud that I FINALLY remembered 'halt' from my old Solaris days...easy way to turn the tablet off while in xterm...)

But anyway, even if you are able to get your dongle running over the OTG adapter, what happens to the power management for the device?

I mean great you can get an ethernet connection or even in my case hook up my wifi evdo modem. Will one get better battery life running over wifi to a pocket/travel router which is wired/connected the whatever network vs. directly wiring in or connecting via the USB port. From what I am seeing the wifi power management is actually pretty good. And I am assuming there will be zero, zilch, nada power mangement for devices over the USB port.

So, as cool as this is, is there really any advantage? If there is no PM then it's doubly important since, under certain loads, the battery seems to drain slightly faster then the charger can replenish the power.

- haven't looked at what 'halt' is linked to on the tablet, but i can tell you that generally one shouldn't use halt to bring down a Linux system... dunno if filesystems are unmounted and services stopped properly... could munge or hork the system?

- best to use:

/sbin/shutdown -h now

- AFA power: i see what you're talking about... the only 'longish' use i see for my dongle/USB connection would be for a serial I/O adapter (used to control an X-10 pad or high-frequency radio transceiver)...

- otherwise i generally just attach a thumbdrive or HD for file transfers and backups...

bluesubaru, sorry about that I missed the actual link on that first post! here it is:
http://www.electronicproductonline.c..._0.1_armel.deb

Steve, very sorry about that but brecklundin is exactly right; there is nothing about the outer shape of the connector that will harm the N800 (it was the solder on the pins that was the original concern as it would actually affect the pins in the connector on the N800), the best thing to do is grab another device (i.e. a USB hub, etc) that has the same mini B connector on it and just work it in a little. I've had everyone one of the adapters plugged into my N800 here before they went out for testing, so they will fit, they just may be a wee bit tight at first.

As far as power management goes, no idea I'll have to do some tests but my bet is that there's very little going on. With a directly powered device (i.e. the LAN adapter, etc no external power) the tablet should not be putting out more power than it can accept from the charger; so with it plugged in the tablet should never "lose"; it might not actually charge, but there shouldn't be a way for it to drain simply because of a USB device. I'd be interested to hear about scenarios that you've encountered this behaviour in though...

Thanks,
-Rob

yeah, good point and probably right...as I recall you are right that 'halt' doesn't go through a proper shutdown as, well, 'shutdown' would. Then again I don't remember if 'shutdown' even exisited on the old Solaris base SparcStation II

Still, I agree completely prob not a great idea in the long term. Not like the power button is too far to reach for...

And yeah, the power issue...it just struck me as funny all of a sudden that even if I went to the effort of convincing the CDU680 to work, I would likely get a lot better battery life using wifi, connection the EVDO router instead. Still it's nice to have the OTG adapter. But to be honest I have never even owned a thumb drive. I know, what a doofus. I just don't venture to a bunch of different PC's where I am unsure what sort of card reader, if any, it might have. Still it is nice to know I could add that 3rd layer of memory (just storage of course) to the system. Now gimme a 32gb thumb drive and we can talk. hehehehe...I could keep my whole library of Audible books on it...and throw in a few movies too. Given the arm and leg required for 32gb SDHC cards right now the 32gb thumb drives seem cheap in comparison.
