 From dmesg:

firmware: requesting isl3887usb_bare
p54: LM86 firmware
p54: FW rev 2.5.8.0 - Softmac protocol 3.0

I think this shows that I have an ISL3887. As further confirmation, it 
uses routine p54u_tx_3887() to transmit.  Are the bugs in 2.5.8.0 and 
2.6.16.0 described on the Web? My device is a Dell DW1450.

The 2-3 hour disconnect is still present with the sequence number 
patch reverted and the MTU at 1300. Still testing.
