u3g supports LongCheer WM66 HSDPA Modem

[Antonio A Hilario]

Hello all,

I managed to get my LongCheer WM66 HSDPA modem working using the u3g driver, 
after several weeks of getting by with ubsa.

The device is a ZeroCD device which uses these vendor IDs:

Mass storage mode: 

vendor 0x1c9e
product 0x1001

HSDPA mode:

vendoer 0x1c9e
product 0x6061

This requires patching /usr/src/sys/dev/usb/u3g.c, in 7.1-PRERELEASE

    {{ USB_VENDOR_HUAWEI, USB_PRODUCT_HUAWEI_MOBILE },              
U3GSP_HSDPA,    U3GFL_HUAWEI_INIT },
+  {{ USB_VENDOR_LONGCHEER, USB_PRODUCT_LONGCHEER_WM66 },          
U3GSP_HSDPA,    U3GFL_HUAWEI_INIT | U3GFL_SCSI_EJECT },
    {{ USB_VENDOR_HUAWEI, USB_PRODUCT_HUAWEI_E220 },                
U3GSP_HSPA,     U3GFL_HUAWEI_INIT },

as well as /usr/src/sys/dev/usb/usbdevs

vendor LONGCHEER  0x1c9e  Longcheer Holdings, Ltd.

product LONGCHEER WM66 0x6061 WM66 HSDPA USB Modem


The driver creates three devices /dev/ttyU0.%d, of which the first is used as  
the device's AT command interface:

Dec 20 16:41:45 emily ucom0: <USB Modem USB Modem, class 0/0, rev 1.10/0.00, 
addr 3> on uhub4
Dec 20 16:41:45 emily ucom0: configured 3 serial ports (U0.%d)

My thanks for the work done on u3g! Device works beautifully under minicom and 
with ppp, and am able to attain ~ 40kBps with our carrier - *without* those 
annoying stalls I got under UBSA.

- Antonio
