D-Link DWL-120 Hacking/Probing

I found 3 or 4 of these at a garage sale a few years ago for a few bucks, and I am (surprisingly) just cracking them open now.

On the front, it is marked as D-Link DWL-120 11Mbps Wireless USB Adapter, on the back is FCC ID# MXF-WL280, H/W: B2, F/W: 2.25

On the bottom of the PCB, we have the following chips:

  • Atmel AT76C503A - Wireless LAN MAC Unit with ARM7TDMI RISC Processor
  • Atmel AT25040N - 4K (512 x 8) SPI Serial EEPROM
  • tmTECH T14L1024N - 128 x 9 High-Speed CMOS Static RAM
  • Intersil HFA3861BIN - Direct Sequence Spread Spectrum Baseband Processor

On the top of the PCB (under the RF shield), we have the following chips:

  • Intersil HFA3683AIN - 2.4GHz RF/IF Converter and Synthesizer
  • Intersil HFA3783IN - I/Q Modulator/Demodulator and Synthesizer
  • Intersil HFA3983IV - 2.4GHz Power Amplifier and Detector

I plugged it into my i386-based laptop (My x64 desktop doesn't have drivers) and got this dmesg:
