Plus those notorious 47k ID R, plus 2 x 15K pulldown on data D+ D-. That's the *real* magic of the "famous Y-cable" ;-) > It doesn't > seem very straightforward to use (a three-way cable ?) but covers all > the cases of cable #2 (hence it is more "universal"). Clearly spoken it breaks USB-specs when used without external power source, as a replacement for cable #2. The 15k pulldowns shouldn't be there because Freerunner is doing the pulldown when powering the USB-jack. So with Y-cable you get 7.5k pulldown instead of 15k. Probably no problem, just for the record. > It definitively > cannot be found in a shop and I guess this involves a cutter and some > dirty electronics to make one.
