The previous text confused users by not describing the very common
(e.g. x86 PC) sitations where no PHY driver is necessary.

I still can't vouch for *correctness* of this text; I'm relying on
other people in the S-o-b chain to do that.

+ USB controllers (those which are host, peripheral or DRD) need a
device to handle the physical layer signalling, commonly called
a PHY.
-
- The following drivers add support for such PHY devices.
+
+ Standard x86 motherboards combine the PHY with the controller
+ and do not need a separate driver, but some systems-on-chip
+ use a separate PHY. This is particularly true for dual-role
+ (a.k.a. USB on-the-go) devices.
+
+ The drivers in this submenu add support for such PHY devices.
