I wouldn't bother cutting your cable. Right now, the neo will only
switch to 500mA charging when it is successfully enumerated as a
high-power device. The only way you'll get it to fast charge from a
power-only source, will be to change the software to something like you
mentioned. It shouldn't need to take 30 seconds though. Once the neo
attempts enumeration (by pulling up on D+ with a 1k resistor), the host
should issue a usb reset (single-ended zero) within 500ms. If that
doesn't happen, there is no host.<br><br><div><span class="gmail_quote">On 7/12/07, <b class="gmail_sendername">Brad Midgley</b> <<a href="mailto:bmidgley@gmail.com">bmidgley@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
