Nightmare live experience - with interesting learnings on connecting keyboards via USB vs. MIDI cable

I was trying to say if it wasn’t a hub problem, he may have been running out of resources which could mean there’s not enough memory address space to support that many devices all at the same time. Just came out wrong.

This from Bright hub:

A powered USB hub connects to your USB port while having an external power adapter connected to it. It therefore draws power from a socket independent of your computer’s power supply. A traditional USB port provides 500mA of current. A bus powered hub distributes this equally among the devices connected. A maximum of four devices can be used with a hub connected to a single USB port.These devices will receive only 100mA of current each. While this may be adequate for devices that do not consume much power, it may not be enough for devices such as USB hard drives or external DVD drives.
When you are connecting multiple devices to a USB hub, Windows may display “USB Hub Power Exceeded” if the connected devices are not receiving adequate power.To solve this problem, a powered USB hub provides the complete 500mA of current required for stable operation of the connected devices.
Apart from providing adequate current at the ports, a powered USB hub provides over-current protection for the devices connected to the hub. This would mean that current provided to the USB ports in a hub is limited to a certain value after which it is cut off; excess current will not be transmitted to your devices, and they are protected.

Also…this is the usb hub I bought. I could only find it at Walmart though. It is a very solid unit and perfectly fit where I wanted to mount it. Was considering a floor unit, but mounted this one, and it works great. Most powered hubs will work, but get an aluminum bodied one. The plastic ones are worthless.
