USB Current Overdraw when screen plugs in

danimal · 09-28-2009, 07:55 PM

A touch screen which i purchased from a member on here... who scammed me telling me it was a liliput screen... none the less i don't know brand or model now and he wont respond so your best guesses will help here.

Anyhow the screen has two inputs Im using, one is a 12v DC power input from AC, and the other is a VGA looking plug that splits into a VGA wire and a USB for what i assume is touch control.

Now the problem... Plug power in, plug VGA into computer and display shows up and works fine, then when I plug in the USB a warning shows up saying current draw on USB exceeded...

Any ideas here, is it the screen?

Thanks for any help.

that type of cable is'nt universal the USB+VGA half to connec to PC, the single end to monitor

Could also be a short.... but hopefully its something simple like a cable backwards
