Hi,

i am using a recently bought FA410TXC with pcmcia 3.1.10. The card is found, but apparently the transmitter isn't enable by default:

Feb 19 16:05:50 localhost cardmgr[380]: initializing socket 1

Feb 19 16:34:14 localhost last message repeated 2 times
Feb 19 16:34:21 localhost kernel: eth0: interrupt from stopped card

I also recognize, that no interrupts are generated by the card, at all.

I had a closer look at the packet driver they ship and came up with this user space program to enable the transmitter and select speed + full duplex:

usage:

fa_select <interface> <option>

option:
0: 10 MBPS/HALF
1: 10 MBPS/FULL
2: 100MBPS/HALF
3: 100MBPS/FULL

I hope it's useful to someone...
