[Q] OTG and Charging

dirkzelf · Mar 6, 2014

I have made a little (amatueristic) video to watch. It seems it is critical to connect everything to the hub, and then at the latest plug in the OTG cable, otherwise it won't charge.

I am using a standard y cable with micro usb with male and female usb so I can charge and use my usb stick at the same time. The only problem is that it does not work on stock rom. Only tried cyanogenmod yet and it works. Does not say charging on lock screen but csn see the battery icon charging. And it is FAST. Also using multirom manager so I can dual boot multiple roms and not lose anything.

I have had success with the OTG Y cable accessing flash storage and charging simultaneously.

At first I didn't think it was working, as the charging animation does not appear. I have been using a blackberry charger 5V 700ma, I have found that if I have the charger already connected to the Y cable *before* plugging into the phone the charging light appears, but still no animation, however battery stats states charging AC. If I connect charger after the OTG Y cable has already been attached to the phone I do not get a charging light.

I put two rather large files on download (to the flash storage) whilst testing this out, as I knew this would usually drain my battery about 20% screen off, went from 66% battery to 76% in 20 minutes.

I am using Linaro Kernel.

When using the setup in the car with hub, USB disk, and charger, it does say that it is charging, but when running a dashcam app or other continuous app that uses GPS and continuous write/delete on the USB drive, the battery actually stille does drain. Maybe it does actually charge, butit is not enough apparently........

Is there a kernel that allows charging without last plugging OTG device?

My goal here is to have car dock setup where I just plug one cable into phone and it enables both charging and additional storage for dashcam app. So both USB and power would be already connected to the cable and I would just plug the Y cable into phone.

sure, it will work, but I have realized the setup is too unreliable, the charge is too weak apparently, and what's more, the recording is tricky, many times the app freezes, or stickmount loses the connection to the USB drisk, what results in stopping recording (DailyRoads) or continuing on INTERNAL memory (VideoReg).

It's too tricky, if you need it to work buy a phone with SD slot or huge memory (32-64GB), or just use a dashcam. I use the Mobius action/dashcam to full satisfaction, would cost some 50 euro I guess. It records reliably, good picture quality and has many useful features.

Besides it is small and has a really easy install form factor. :good:

Good luck!

I noticed that with a OTG+charging Y cable my Nexus 5 does also not show that it is charging.
Is there a fix meanwhile?

Thank you
