 Hi,
	We've developed a device driver for a PCMCIA multifunction card
with serial and USB functions for kernel 2.6.15.4. Now we're porting
this code to 2.6.16 and 2.6.17 kernel versions. The issue that we're
facing in kernel 2.6.16 is that when we do a hard-eject of the card
(remove the card physically), we get the "hub_port_status failed (err=
-19)" message in /var/log/messages

Please refer the following kernel log:

However on re-insertion the card does get bound to the driver properly
and the configuration is successful. Even the devices connected to the
usb function work fine. But upon the card removal(hard eject),the
same(above mentioned) messages occur. The occurence of these messages is
also not consistent. Sometimes the removal happens gracefully.

These messages do not occur during software removal (pccardctl eject)
and software insertion (pccardctl insert).

They also do not occur in case of kernel 2.6.17 and 2.6.15.

I think that somehow the hub_status_data is getting executed (due to the
invocation of the roothub thread), before the remove(detach) function is
called.What could be the reason for the occurence of these messages?
