Tekram AIR.mate U300C (Intersil)
Per Tekram's website (via archive.org), there appear to be multiple revisions of the device. From the driver files, all revision prior to v2.5 are 0b3b:1612 ID devices. v2.5 devices have 0b3b:1601 IDs and use the Intersil PRISM 2.5/3 chipset. The Tekram link also includes drivers for the device.
The FCC ID is probably O6M-UW250 (BroMax UW250).
