When my Dell Zino-HD boots, it connects to the internet automatically; the wireless card is:
--
Bus 001 Device 002: ID 413c:8104 Dell Computer Corp. Wireless 1450 Dual-band (802.11a/b/g) USB2.0 Adapter
--
and it is loaded in the following manner on boot:
--
sudo cp isl3887usb /lib/firmware/`uname -r`/isl3887usb
sudo modprobe -r p54usb | modprobe -r p54common
sudo modprobe p54usb | modprobe p54common
--
and the driver used is:
--
isl3887usb (from http://daemonizer.de/prism54/prism54-fw/).
--
I can connect fine, and speed is decent. But as soon as I plug in my USB Webcam:
Bus 001 Device 004: ID 046d:0819 Logitech, Inc.
Wireless Internet pops up as "disabled" and in order to reconect, I must reboot. To note, My webcam is

Latitude Webcam C210

And the dmesg output is:
