Too Much Wear From Plugging/unplugging The Usb Cable

Im doing development on my Wiz and every time I test a build I need to unplug the USB cable in order to reconnect to the wiz.

Is there a way to do this connect via software or through the GUI? I can't seem to find anything in the settings to connect USB
so the only way I can get to that black "Choose a disk" screen is by unplugging the USB cable.

The physical port on the Wiz doesn't seem too sturdy and I'm worried about
too much wear from my constant plugging/unplugging the USB cable.
 
I have similar concerns at the user level and have been doing some exploring into this subject as something of a hardware hacker.

As it is, I do all my transfers to my memory card using a card reader and I only use the cable for charging.
However, if anything happens to the connector on that cable, or ghod forbid on the Wiz, you are just plain SUNK.

For software developers a custom cable harness with some kind of a switch connected to the power and data lines would allow you to remain physically connected while still being able to electrically connect/disconnect from the computer.

I know for a fact that it is an LG cell phone connector being used on the Wiz.
The trick is to find a source of the generic connectors with all the pins present to allow for custom charger/data cable fabrication.

I tried using an old LG charger, but it is using different pins for power and the pins needed for Wiz aren't accessible, thus the need for a generic connector with all pins present to do any custom cables.

If I can find a source of generic connectors and/or get anywhere with custom cables I will post any and all information here.
 
Why not just attach a USB male to female male cable and keep unplugging/plugging a USB extension cable to that? I guess this might decrease the number of times you unplug from the physical port noticeably.

It's possible to "unplug" USB in software, it works with Linux at least, I do this on Wiz over serial:

to "connect":
Code:
insmod lf1000_udc.ko
umount /mnt/sd
insmod g_file_storage.ko file=/dev/mmcblk0p1 removable=1 stall=0

to "disconnect":
Code:
rmmod g_file_storage.ko
mount -t vfat /dev/mmcblk0p1 /mnt/sd

If you don't have serial cable you can make .gpe scripts out of those and run them from NAND (as it unmounts the SD to sync).

Of course!

Simple and elegant...and obvious. (Probably why I missed it.) ;)

handy tip again! i think you should put up a snippet page with all your trickeries :)

If you just do 'strings gp2xmenu', and look carefully, you'll see the commands the menu shells out to perform these operations.
