The USB connector on my MDI was falling apart & dodgey so I removed it but wondered if anyone knows what wire goes to what?
On bottom from left first is left empty & then white
Then I can put the shield to either of the big bottom holes which was supports for USB connector
I think from top left to right is black then greeen then redUSB wiring to MDI

Re: USB wiring to MDI
From left to right, ignoring rows, it should be :
Black, Nothing, Green, White, Red.
So, that matches what you came up with.

Re: USB wiring to MDI
i had the same issue with mine, i got usb connectors off ebay pretty cheap, might be a better solution ?
unfortunately mine doesnt work with the new plug, need to test not sure if i've shorted two together, too small for my liking!

No matter what the question is, the answer is always more horsepower!

Re: USB wiring to MDI
Yeah I thought it may be my soldering skilled too but all looks & tests well with multimeter as none are connected with open loop shown to all except earth & white which is high resistance & not zero so thinking that’s normal.
Then there is 5v to red between it & black, it also shows 5v to red from the shield wires to as I have them connected to outer big holes but not sure if I should have them connected & may try cutting them off & see if it helps as it’s not recognising the device.

Re: USB wiring to MDI
so I tried all other options & nothing fixed it connecting to device, so I have ordered another MDI & will attempt to fix this issue later but think I have lifted pads when soldering as it is dual sided PCB.

Re: USB wiring to MDI
you can see the components the pads link to, you could try soldering to the end of the components. I think that large green component is a fuse, might be worth checking for continuity across it.
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396
Re: USB wiring to MDI
The two large green bits are Polyswitch resettable fuses. Unless faulty, they don't "blow" as such, like a conventional fuse (but it doesn't hurt to check them anyway).antus wrote:you can see the components the pads link to, you could try soldering to the end of the components.
