Some USB-interfaced equipment simply will not properly establish a connection if physically connected during the boot-up process of windows. This means that every time the computer is restarted you need to unplug and replug the USB device. If the computer is operated and power-cycled remotely then there is no simple way of reestablishing a connection to the equipment. It's frustrating! You try everything you can in the bios relating to power settings and the USB controller, but nothing works!
This device introduces a time delay before relays are engaged that connect the power and data lines to the USB-interfaced equipment. Previously made for work purposes, this new version is much cheaper and controlled by a microcontroller. The aim is cost savings with an emphasis on small-scale mass production and an appealing look. It cannot be a solder kit or sold without an enclosure, as the target audience (IT professionals) will not buy it.
Well, here it is. The first board has been assembled which will now allow me to write and debug the micro controller code. Once this has been done I can send off the hex file for Digikey to pre-program onto the micros to avoid the programming problem.
But first to make a jig to align pins to actually connect to the micro-controller...
The parts for the first assembly of V2 are here! There's enough for 5 assemblies. Goals are: -->Do they work? -->Write microcode/verify -->Is the LED useful? (looking for parts to remove). -->Design new enclosure.
