Rumba board

Guys

I have a rumba board with a problem

I though it had a faulty USB port but I replaced this with no effect

When I plug into laptop the power light flashes for a split second, that's all. Sometimes (possibly once in 100 tries) the laptop detects the board but again only for a split second.

I have swapped jumpers etc for USB power.

Anyone have any ideas or an up to date schematic?

My board is the one with the reset button behind the USB port

Thanks

On what you have, you have to ask the vendor ... or build an electronics from schematics' available.

Sorry, I dont understand what your saying?

The link Traumflug posted is the latest schematic that RepRap.org has. If there is a later one, you need to talk to the people who sold you your RUMBA board (or the people who designed RUMBA) to either supply you a later schematic, or to update the RepRap.org wiki with a later schematic.

Did you resolve this issue? I have the same problem.
