Hi, I have a Dell usb wireless card that I am trying to use under Linux. A search of the FCC-ID M4Y-XG705A lead me to believe it has a Z-Com XG-705A chipset. Another search tells me that the p54usb driver should work. So I added {USB_DEVICE(0x413c, 0x5513)}, /* Dell Wireless */ to the /usr/src/linux/drivers/net/wireless/p54/p54usb.c file in the correct spot. A quick recompile and the module was built. I did a modprobe p54usb and dmesg shows: cfg80211: Calling CRDA to update world regulatory domain usbcore: registered new interface driver p54usb cfg80211: World regulatory domain updated: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) However iwconfig doesn't list a wlan0. OK maybe I need firmware so another search leads me to http://wireless.kernel.org/en/users/Drivers/p54 where I download 2.13.24.0.lm87.arm (USB 2nd generation (ISL3887)), rename it to isl3887usb and put it in /lib/firmware. I rebooted and still no wlan0 listed in iwconfig. What did I do wrong? Thanks, Greg The lsusb -vvv for the device is: Bus 001 Device 003: ID 413c:5513 Dell Computer Corp.
