No, not necessarily. RTL8187 is a chip used in many devices. The easiest way to test if Fedora Linux supports the adapter is to install Fedora Linux on a PC, then insert the adapter. That URL is many years old.

So rebuild kernel with CONFIG_RTL8192CU set and normal function may occur. 1. http://dev.laptop.org/git/olpc-kernel/tree/drivers/net/wireless/rtlwifi/rtl8192cu/sw.c?h=arm-3.5#n273 2. http://dev.laptop.org/git/olpc-kernel/tree/arch/arm/configs/xo_4_defconfig?h=arm-3.5#n1191 > I thought that a compatible hardware list on WIKI is welcome. Yes, that would be nice. But the problem is that the list is made out of date within a few weeks when new devices are sold. The same model of USB device may use a different chip and driver next month. Difficult task to track. I'm glad you can volunteer. ;-) -- James Cameron http://quozl.linux.org.au/ _______________________________________________ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
