DWM-222 rev A2

Hi folks, I have purchased a DLink DWM-222 with the intention of exploring the Linux OS running inside it, and if possible, compiling some additional USB gadgets to use with it. FWIW, the USB ID's are 2001:ac01 before modeswitch, and 2001:7e3d after switching. It creates ttyUSB[0-4] when switched, and the VID:PID added to the option driver. I was wondering if there had been any further developments in the exploration of the A1 hardware or firmware, in terms of gaining a shell on the device at all without soldering? Some initial probing has shown some 1.8v signals on some of the test points, so I will check those with a scope while booting to see if I can identify some waveforms, hopefully indicating a UART. I do have a FTDI UART with a voltage reference, so I am fairly confident that I can access those signals without damaging the device once identified. Unfortunately, the updated hardware has complete shields over the interesting bits, so I cannot identify chips, etc. I have also not been able to find firmware for the A2, the only firmware I could find was at ftp://ftp.d-link.co.za/DWM/dwm222/Firmware/, marked as A1. I'll check to see if they are compatible. And of course, will be copying the driver software from the embedded CDROM. Regards, Rogan
