Your network's passphrase is a string that just happens to look like a
hex number. It's still just a string to the algorithm that uses it --
are you sure you entered it correctly? It's a _case-sensitive_ string,
for one thing...
The psk for WPA-PSK is either (A) calculated from the network's SSID
and a passphrase (string) of 8 to 63 characters, or (B) entered
directly as a 64-character hex value. That's part of the WPA spec. The
other operating systems' user interfaces may not require quotes around
it, but they're still using that 26-char string as a passphrase,
because at that length that's all it can be.
You can see what the actual psk is by passing your SSID and passphrase
to the wpa_passphrase utility that's part of the hostap package. The
output is even in the right format for your wpa_supplicant.conf
