You've measured wrong!
Power supplies current are rated on output voltage. PSU with 2A means on 5V. No one care how much it draws on 110V - it will be of course very small current.

Dang it, you're right. I fixed my previous post. The correct current is 1.1A @ 5V = 5.5W.

Hi, I was looking for some advice...

I have just ordered some USB Hub boards from PCBWay and I have had a question back asking

"Ref attached screenshot, the pointed out place have plated slot, but no soldermask opening there on top side.
Should we add soldermask opening there ? "

I am not sure what my response should be.

Can anyone help?

TIA

it's on purpose, to prevent USB connector touch the 5V line. Option with 5V connector is soldered on the bottom where solder mask is present.

I'm after some advice - I'm going to start assembling USB hubs soon, a couple of questions to those who are are in the know please;
LED 15 - when the USB hub is powered but not connected this indicates that the FE2.1 IC has survived the install and is operating OK?
The USB cable should be wired like this?

Can I test the USB hubs by wiring on a USB type A standard cable and plugging into a PC?

Any help appreciated =]

I've build the USB hub and have a question.
When I plug an USB device like keyboard and mouse the Green LED is on. It's working as it should with keyboard mouse and joypad :-)

When should be the amber LED on ? It's never lighting.
How can I check if the LED is working with the MiSTer ? LED were checked with multimeter and they are OK.

Thanks

It's unclear when amber LEDs should lit. I think it's ok not to solder amber LEDs.
