I have a hard time interpreting the meaning of device in this context.

In that line, device means:
2. A project or scheme, often designed to deceive; a stratagem; an artifice. Source: Wiktionary
In other words, the song is saying that we are all prisoners by our own means. We weren't tricked into this situation by anyone else; if we were tricked at all, we tricked ourselves. Our own plan put us where we are.
As noted in a previous answer, device can mean a "project or scheme ... a stratagem; an artifice," whence a "prisoners by our own means" interpretation.
That general idea is almost certainly correct, and own device is sometimes used that way, but (examining some references from ngrams) one finds that own device is frequently used with its "piece of equipment made for a particular purpose" meaning, while own devising more frequently refers to strategems or plans made by oneself.
In the subject lyrics, the context is
The pink champagne on ice
And she said "We are all just prisoners here, of our own device"
which suggests to me that the Eagles used device rather than devising to get the rhyme with ice.
device here is a metaphor for "your own doing". so it means here that we become prisoners by our own thoughts and our own actions... hope that helps!
I think it's basically a word mis-spelling/mis-use. The correct statement appears to be, "we are all prisoners of our own devising. I.e., we've all made ourselves our own prisoners.
cf. 'Left to one's own devices.'
This is probably the only example of a phrase still in common usage which preserves the older meaning of 'device'. The same meaning applies in the lyric.
As @Tom Au points out, by far the more common phrasing is of our own devising...

...so although the Eagles' lyrics aren't actually incorrect, they're an even more unusual way of introducing what's effectively an archaic usage already (the word device here actually means devising anyway, not the more common modern noun meaning of an artifact/machine). As others point out, by our own devising means through our own thinking (unhelpful preconceptions).
Even if you wanted to take "device" as the modern term for "machine/artifact" the lyric still kind of makes sense.
Because if we were to interpret it as "we are all just prisoners here of our own device (artifact)", it still would sound like we are saying that we are controlling ourselves into that situation. Our device is in us or in our hands or whatever. We imprisoned ourselves with it.
Maybe I am just rambling, but I think either interpretation of the word is correct because either way we imprison ourselves, not forced by another entity.
