I think I found the driver. It's a generic firmware, but it's really old (pre 2.7.0.0).
You should go to <http://wireless.kernel.org/en/users/Drivers/p54> and get the latest
one from there for your device (isl3887usb > 2.6.29).

This should be the right location and filename for the firmware.

I can't find this device-id in the p54u_table. Did you add it manually?

Is this output cropped? p54usb announces which firmware file it requests.
Furthermore, In your case you should have seen something like this in dmesg:
"wrong firmware, please get a firmware for "isl3887usb" and try again."

Looks like the firmware on the device crashed. You should physically disconnect and
reconnect the stick before trying again.
