DVD drive with USB micro-B cable?

Mon Dec 04, 2017 11:51 pm

Looking for a cheap external USB DVD drive that has a micro-B socket on the back (most have the old square B that I have seen). Are these common/rare/nonexistent?

Reason for asking is to try and power one with a PiDrive cable, in an HTPC build.

I believe the designs transitioned directly from mini USB to USB 3.0 and now, some USB C.

If they're USB 3.0, you might be lucky, the spec uses a standard micro USB B on one half of the plug and power on the other half via another USB style I forget the name of for power.

Anyway, if you have both cables, you can use them (sacrificing 2 USB ports) or just use a proper USB 3.0 cable
Be absolutely sure you have the right cable though.

Just found this for any slim SATA drive:

This should do the trick...

Like many of imperf3kt's answers on these forums this one matches his username.

A look at eg http://pinoutguide.com/visual/gen/micro ... nector.jpg will show that the added half (compared to USB 2.0 5-pin micro-USB) carries data and no 5 volts.

But yes, the 'old half' is physically and electrically compatible with USB 2.0 micro-USB specs and the device should be backwards compatible to work in USB-2 mode if connected with a USB 2.0 USB to micro-USB cable.

Ah yeah, sorry, I misworded my original post and after verifying my mistake I forgot to edit things >.<

In the most basic sense, you can use a USB3.0 device, over a Micro B USB cable.
