I have a TS-7400 that is straight out of the box. I've tried to use
the IOGear GWU253 USB Wifi device but I get a Seg Fault. Has anyone
had this issue before? Is there a simple way to solve this?
Exact set of steps:
0) Kernel on my SD card inserts a bunch of modules on boot: usbcore zd
pcipool usb-ohci usb-ohci-ep93xx af_packet
1) I then run, as root,
# insmod /lib/modules/2.4.26-ts11/kernel/net/zd_b.o
2) output of dmesg:
...

2) I insert the IOGear module into the usb port. New output of dmesg:
