>Description:
The ZTE MF626 key is a usb wireless 3g key.

After plugging and ejecting the pseudo cdrom driver (eject /dev/cd0d), a serial 
modem should come up. It doesn't because the device product id is not in the 
list of known devices.

After plugging the key, dmesg says:
umass0 at uhub5 port 1 configuration 1 interface 0
umass0: ZTE, Incorporated ZTE CDMA Technologies MSM, rev 2.00/0.00, addr 2
umass0: using ATAPI over Bulk-Only
atapibus0 at umass0: 2 targets
cd0 at atapibus0 drive 0: <ZTE, USB SCSI CD-ROM, 2.31> cdrom removable
>How-To-Repeat:
Plug a ZTE MF626 key in a usb slot. Eject /dev/cd0a; eject /dev/cd0d
>Fix:
Apply following patch (note: diffs in generated usbdevs.h and usbdevs_data.h 
not included).

After patch applied, and eject /dev/cd0a; eject /dev/cd0d, dmesg says:
cd0(umass0:0:0): not ready, data = 00 00 00 00 3a 00 00 00 00 00
cd0(umass0:0:0): not ready, data = 00 00 00 00 3a 00 00 00 00 00
umass0: at uhub5 port 1 (addr 2) disconnected
cd0: detached
atapibus0: detached
umass0: detached
