Thank you...
I am using usb_sndbulkpipe in usb_bulg_msg
the return value of the usb_bulk_msg is also a positive number. But there is
no response from
the device.. Can suggest some free tools to monitor the data on USB in
Linux.
Thanks in advance

You forgot to document what
Checks if 'port' is NULL before using it in all tty operations, this
can avoid NULL pointer dereferences.

Fixes open()/close() race-condition in the access of the port structure.
When the race happens, the port in use becomes invalid, and the user must try
to get the next free port (repluging the device, for example).

Greg,
I'm sending two patches for the usbserial NULL pointer dereference we
discussed last week:

Hi All,
I have a MPC 8270 based board on which a Philips based ISP 1561 (
PCI - USB ) connected to it. I have a self powered device connected
to the host. Whenever I restart the host alone, the device fails to
enumerate and returns -71 (EPROTO) error. However, if I switch off
both the host an
