idProduct: 0x0200
bcdDevice: 0x0000

and uses 2 endpoints with below attributes

bEndpointAddress: 0x01 OUT
Transfer Type: Bulk
wMaxPacketSize: 0x0200 (512)
bInterval: 0x00
Endpoint Descriptor:
bEndpointAddress: 0x81 IN
Transfer Type: Bulk
wMaxPacketSize: 0x0200 (512)

At this stage, there is nothing about 3G USB modem. So this unit requires some switching to 3G USB modem mode. Next will install the driver the comes with the unit as a CD emulation drive.
