I getting panic: ohci_rem_ed: ED not found when removing similar UMTS
card (Option Globetrotter GT MAX 3.6/7.2).

I have gathered various debug info at

http://akson.sgh.waw.pl/~saper/FreeBSD/gt/

What's interesting, I cound not find any reference to "ohci_add_ed"
while running at USB_DEBUG level 8 in my dmesg:

http://akson.sgh.waw.pl/~saper/FreeBSD/gt/msg

My stack backtrace:
