Has anyone looked at the CyberPower battey powered USB hub, cph420mp ? I just ordered one from Amazon for about $20. I figure that a little rewiring to supply power back to the 770 and it will be ideal. Already has rechargable batteries and a charging circuit. I am not real sure how it charges, via usb or what. I will post more when it arrives, hopefully by Friday.

PS. Just read the online manual and it charges from a live USB port on your computer in 6 hours. Also the batteries are easily removable with a door on the back. It uses 4 AAA NiMh batteries and comes with 650mah rated batteries. So you are free to substitute higher capacity batteries and fast charge them outside the hub. Looks very nice.

Hmmm, I just tried my little power box (with a fixed battery pack I hope - I only charged it for a few hours last night so it still says it is flat so we ran it off a wall plug pack) with a USB keyboard at work and that works fine. So my keyboard repeating key problem is keyboard related. I am using the targus stowaway USB keyboard. Now normally with a Palm of Pocket PC there is a little driver that lets you change the repeat rates in software on the device. If I plug the Stowaway into my XP machine it works fine in that. There must be some way to do this on the 770? I was thinking maybe the xset770 -r command might help but it is only for individual keys. I would try it but I have no idea what the keycodes are?

Yes, this baby was spotted before and mentioned here a few times a while ago. It does seem to fit in quite well with the little quirks of the 770, but so far no one has reported here on actually using it, so please do.

The problem with the CyberPower is that it's almost impossible to come by for non-US users. Most mail-order sites that carry it (including Amazon) will not ship abroad ; in Europe, only the german and british amazon sites offer it, and they also have that stupid policy of shipping only domestic. I would have given it a try if Amazon.fr was willing to sell it, but at the time it does not.

I got this one. I haven't tried it with Nokia yet, but it worked great with my Sharp Zaurus - it was able to power an external 2.5 100 Gb.

I use it with my nokia 770. You've got to wire +5V directly from
batteries trough an 1n4001 diode (to drop 0.6 V) to the hub
and to the nokia 770.

wire: batteries 5V aproximately ----- diode >| ----- hub and Nokia770

It is necessary to power the hub usb input with 5V from
its own batteries for it to run.

Here (attached) is a draw of what i've done to use
the cph420mp with the nokia 770. Note that you've
got to power with aproximately 5V not only the
nokia 770 but also the usb input of the hub itself
(I took 5V from the batteries of the hub, through
a diode 1n4001 to drop 0.6V because batteries
give 5.3V or 5.4V, not 5.0V)
