It is just a workaround for a kernel bug. It is this bug that must be

PLEASE when you provide kernel output, do it VERBATIM. The above lines
are incomplete which renders them useless.
If you can recompile kernel - please, add CFLAGS += -DDEBUG on top of
drivers/usb/Makefile (and possibly drivers/usb/hcd/Makefile). It gives
additional output that can help in finding exact place where it hangs.
Note that it should hang just as well when you simply do service pcmcia
stop. Is it the case?
If you do it please send me
- kernel messages. EXACTLY as they appear
- output of lspci -nv and lsusb with card plugged in.
