I continued the hardware design I added : - a switch, to choose between SIMtrace and normal SC reader. the USB CCID profile could be loaded during boot. VCC can be supplied to power the SC. - switches for the SC presence, included in the sockets - LEDs to show the current mode (green=reader,yellow=emulator,blue=sniffer,red=MitM) - transistor array to control the LEDs, SC connections, and I/O line - line names - .... as I'm not an electrician, could someone check if this could work, resistors/capacitors are missing, .... here the schema : https://gsm.tsaitgaist.info/SIMtrac/v0.4/SIMtrac.ps Kevin On 24.11.2010 09:17, ml at mail.tsaitgaist.info wrote: > To be able to choose between 1.8v (class c) or 3.3v (class b), there is > a manual switch.
