axe0: usb error on tx: IOERROR

Hi,

My Netgear USB Ethernet stops working after transmitting a few packets.

ehci_idone: need toggle update status=80028d50 nstatus=80008c80
ehci_idone: need toggle update status=80028d40 nstatus=80008c80

axe0: watchdog timeout
axe0: usb error on tx: IOERROR

This happens on the following system:  
FreeBSD jim.arved.de 5.3-STABLE FreeBSD 5.3-STABLE #4: Thu Nov 18 17:33:47 CET 2004 arved at jim.arved.de:/usr/obj/usr/src/sys/JIM  i386

With older versions it suffers from the bug fixed in if_axe.c rev 1.22

Anyone got an idea how to debug/fix this?

regards
