Pertaining to the UV-5R series of phones, I have seen numerous times that the volume needs to be turned up.
Let's once and for all dispel or confirm this.
I for one have found, and it makes total sense to me, that the volume has absolutely nothing to do with data being transferred to a computer with the data cable.
Please confirm or deny.

This too does not make sense to me.
The pinout for the 2-pin Kenwood style plug used on the majority of these Baofeng (and Baofeng like) radios has the analog speaker/mike audio wires separate from the digital RX data/TX data wires used for programming. The programming cable only contains the 3 wires needed for programming (RX data, TX data and ground). The programming cable does not contain the wires for speaker audio (SPK+) and mic audio (MIC+) because neither are reauired for programming (it is the non-existent SPK+ wire that has its signal level adjusted by the volume control knob).
I have been programming many brands of radios with many kinds of programming cables using many different computers having various operating systems for over 7 years. I have never ever had to intentionally rotate the the volume knob to a point any further than it takes to provide the "click" that supplies power to the radio (which coincides with the lowest volume level).
That being said, I have had email exchanges with those trying to solve their programming cable issue that eventually sorted out the issue by turning up the volume and swore they the replicate the issue by turning the volume down. To me this should not be the case. Perhaps there is a design flaw that shows up in some of these cheap radios (or radio/programming cable combination) that has the data TTL levels affected by volume control?
