Quoting from VisorCentral News off of my AvantGo site (for those who never read the news on the main site):
There is no power drain when the Visor is off. When the Visor is on there is power drain up to 15 mA) because the USB chip sees the PC usb hub. Serial cradles do not have any power drain because the USB chip is off all of the time.
This opens up a new range of possibilities, and questions. I have listed a few of mine here.
1) Now that means we can leave our Visor's in the cradle and have the computer perform a USB hotsync in the morning before we wake up. If using avantgo, the modem can also help wake us up. :-) Does anybody know how to have the computer do an automatic hotsync?
2) Why didn't handspring build the USB chip into the cradle, and power the cradle using the USB's on-demand power supply, and use an interface between the visor and the cradle that would, for example, provide power into the visor's port telling it to "wake-up" and start communicating rather than having to activaly monitor the port, or even better, power the visor completly during hotsyncs, causing zero power drain. Heck, it could even charge nimh's, or heres an idea: Put in a Lithium battery (charged via the cradle) add the option for a seperate adapter connected to an external pack which would hold alkalines, for extended trips away from the computer. And it could, in theory, charge the Lithium through the USB port rather than an external power port. OK, I'm going on now, but I still think it would have been a good idea. Mabee for the next visor, which will probably have a color screen too, forcing them to have some means of recharable power source to keep the power consumption from killing your batteries. :-)
