uhmodem: device driver for huawei 3G wireless modem
* what it is?
A device driver for huawei 3G wireless modem, E220 and its valiations.
The devices are very simuler to ubsa device, but they need special care
to use as modem device.
This patch introduce "uhmodem (USB Huawei modem)" for the devices.
A uhmodem device has two com devices and one USB mass strage device.
The driver enable to use all of them.

really the same...)
Fixes problems with Sony Vaio memory stick slots, which advertise themselves as
"ATAPI over CBI".
Remove the quirk for Fuji cameras, since this is almost certainly the same bug.
* We were never calling the callback function when we got a UFI CCI(!).
* We were passing a bogus residual count on non-UFI CCIs.
* After a REQUEST SENSE, the UFI CCI may include the ASC/ASCQ from the sense
information -- don't consider this a failure.
In addition, remove a horrible hack that was causing us to drop sense
information on the floor and return empty INQUIRY responses, often in the case
where there is a UNIT ATTENTION pending during the INQUIRY. (Some drives send
the data and then fail, some don't.)
This eliminates the need for quirks for the Y-E DATA FlashBuster.
These changes work on:
umass0: SAMSUNG SFD-321U [FW 0C], rev 1.10/2.10, addr 2
umass0: using UFI over CBI with CCI
sd0 at atapibus1 drive 0: <SMSC, USB FDC, 2.10> disk removable
umass0: TEAC TEAC FD-05PUB, rev 1.10/0.00, addr 2
umass0: using UFI over CBI with CCI
sd0 at atapibus0 drive 0: <TEAC, FD-05PUB, 1026> disk removable
umass0: Y-E DATA FlashBuster-U, rev 1.00/3.04, addr 2
umass0: using UFI over CBI with CCI
sd0 at atapibus0 drive 0: <Y-E DATA, USB-FDU, 3.04> disk removable
support it, we'll just get an ILLEGAL REQUEST and ignore it. Furthermore,
on the PQI Travel Flash at least, it works just fine without. These seem to
have been added in omnibus changes for particular devices, along with other
"quirks" that are now gone. Adios, we won't cry for you.
