question

Could you clarify what this is for? Are you asking about the resistance value between pins 4 and 5 of the USB client device attached to the Fire? That should be done by the manufacturer according to the USB spec.

Many thanks for your reply NickG :)

But this is misunderstanding unfortunately.

This is about switchON OTG host + charging of host device together.

By the USB Standard is OTG host function switchedON at host device (phone, tablet, etc.) by short connection = 0 Ohm between pins 4 (ID) and 5 (GND) on microUSB male plug.

If you want swichON OTG host function + charging of host device together, this provide by USB Standard resistance 124kOhms (even is allowed range 119 - 132 kOhms) between mentioned pins 4 and 5.

Problem is, that almost zero producers incl. Amazon respects USB Standard i.e. each, if enable possibility of OTG host + charging host dev. together, select own value of switchON resistance.

I'm asking, if somebody know, which value is valid for Fire 7" 2015 = 5th gen. = model KFFOWI.

Thanks a lot in advance :)

Have a nice day !

Best regards,

Peter

to add:

OTG host function of phone, tablet etc. is switchedON usually by special connector / cable reduction from USB A female type to microUSB B male type.

Unfortunately activation of standard OTG host function (by short circuit = 0 Ohms between pins 4 and 5 at microUSB male plug) terminate charging of host device although charging 5Volts is present.

I need use various USB A male connectored devices together with charging of Fire 7" tablet at same time. This situation should to be solved by right value of resistance between pins 4 (ID) and 5 (GND) & standard charging 5Volts between pins 1 (+5V) and 5 (GND) I hope ;)

hi, I have the same issue and was wondering if you found the answer? I tried 100k and still no go.

I guess you could call me a newbie although I've been messing around with store-bought OTG cables for a few years now I'm just a basic user wear if I have a OTG capable phone or rooted device that recognizes OTG when plugged in I've always known it to be at 100,000 resistor between pins 4 and 5 however I'm having a thought I'm ready to walk out the door right now to go to Fry's Electronics to buy a couple micro USB plugs to make up a custom cable to tether my my Android to my laptop running a Ubuntu 18.04 the beaver version and I'm wondering in my head tossing around the idea of a switched connection at the end of my cable where I can Engage The resist or not ? I'm currently trying to use an alpha network adapter that's programmable to run Kali Linux on my LG Android phone I'm going to create the module people want to call it a driver but I think the correct term is Imago when you're speaking Linux it's going to handshake my device with the network adapter and allow me to go into monitor mode I'm a little out of the realm of the question here but if somebody has any thoughts on my idea please reply thank you
