r8192_pci/r8192ce are Realtek drivers for PCI-E devices and r8712u/r8192u_usb are for USB.
They are included in the staging tree at linux-2.6/drivers/staging and they are NOT supported by linux-wireless developers or mailing list.
Instead ask for support in http://driverdev.linuxdriverproject.org/mailman/listinfo/devel or to the maintainer, Greg Kroah-Hartman < firstname.lastname@example.org >.
The r8192s_usb driver has been dropped in favor of r8712u, as this http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2865d42c78a9121caad52cb02d1fbb7f5cdbc4ef.
r8192ce is based on mac80211 and supported by linux-wireless.
