Mr. Kevin, I was never reported for that product id 0x0132. Yet you can continue support for it if it is rare. In the meantime, we can add more devices to the header and add those names to "usb_device_id" table in "InterfaceInit.c". I added a new product string "BCM_USB_PRODUCT_ID_ZTE_326" and also modified the device id table. Again, I removed product if 0xbccd because Beceem, ZTE, Sprint use this id for the block device containing device driver. Again, this is always switched to base product id via udev. Here is my dmesg output when udev is turned off. ===== root@inspiron:~# dmesg -c [24449.439134] cdrom: issuing MRW background format suspend [24459.102669] usb 2-1.2: new high-speed USB device number 11 using ehci_hcd [24459.336258] scsi11 : usb-storage 2-1.2:1.0 [24460.334906] scsi 11:0:0:0: CD-ROM BCM-CD V 01.02 01.01 1.13 PQ: 0 ANSI: 2 [24460.336721] sr0: scsi3-mmc drive: 0x/0x xa/form2 tray [24460.336971] sr 11:0:0:0: Attached scsi CD-ROM sr0 [24460.337167] sr 11:0:0:0: Attached scsi generic sg1 type 5 root@inspiron:~# mount /dev/sr1 /media/tmp mount: block device /dev/sr1 is write-protected, mounting read-only ===== I did build after these changes and probed the module. It works perfectly. I also tested 0x0172 and 0x0173. No error is reported. So I assure that these products are valid. Not sure about 0x0132.
