btw: That's only works if the port you connect to allows high power devices. Most laptops have only one physical port which will let you enumerate as a high power device, and sometimes even that port only allows it when you're plugged in. So, hopefully the phone will be able to attempt enumeration as a high-power device first, and if nak'd, enumerate as a low-power device. In that case, it would be nice if there was some indication that the battery isn't being charged, or isn't being charged very quickly, whatever the case would be.
Also, I haven't checked, but I'm assuming the Neo is a full-speed device. If that's so, there's really no difference to speak of from usb1.1 and usb2.0. both specs have full speed devices, with little changes in 2.0. usb2.0 added high-speed devices. I often hear people say usb2.0 when they mean high-speed, but the two are not equal. Just want to make sure that isn't happening here. --Steve On 5/10/07, Joe Pfeiffer <[EMAIL PROTECTED]> wrote:

That doesn't follow -- USB 1.1 allows a device to identify itself as "high power", and it can then be allowed to draw 5 unit loads (500 mA). _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
