This is a note to let you know that I've just added the patch titled
USB: serial: option: Ignore card reader interface on Huawei E1750
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Hi,
my Huawei 3G modem has an embedded Smart Card reader which causes
trouble when the modem is being detected (a bunch of "<warn> (ttyUSBx):
open blocked by driver for more than 7 seconds!" in messages.log). This
trivial patch corrects the problem for me. The modem identifies itself
as "12d1:1406 Huawei Technologies Co., Ltd. E1750" in lsusb although the
description on the body says "Model E173u-1"
