Hi All, great thread going here, interesting and helpful information
I was looking to mod my USB desk dock (non-pogo, just microUSB) to trigger Dock Mode. Unlike the rear pogo port, a 1Kohm resistor does not do the trick. However, I found that a 1.5Kohm resistor does in fact consistently trigger Dock Mode. Unfortunately
, this also activates an "audio-out" mode (i.e. CR S650 with speaker), so the on-phone speaker is deactivated. I suspect the same may be true for activating Dock Mode via the pogo port, in case anyone was planning on making a pogo-pin dock without a speaker (but if you can confirm otherwise, please let me know!!!!).
Maybe someone has some ideas as to how to make it not activate audio-out mode? I'd like it to trigger Dock Mode, but leave the built-in speaker activated. It seems to deactivate the speaker even if pins 2-3 are shorted for non-data, fast-charge mode
. Perhaps I'm actually triggering an audio-out version of Desk Dock, instead of the desired (and hopefully existent!) non-audio-out Desk Dock Mode?
Any ideas are welcome, and any help would be much appreciated! (In my free time, I'm digging through kernel source to see if I can at least find the various mode ADC values to calculate the resistance for
